Dropper posts allow us to adjust our saddle height with the push of a lever, helping to enhance comfort, efficiency, and, most importantly, control while out on the trail. Many people would argue that dropper posts are one of the most important innovations in mountain bike technology — essentially transforming the way we ride.

　　The ability to adjust the height of your saddle on the fly ensures that it is always positioned perfectly for the terrain you are riding, and dropper posts have become a staple on nearly all new mountain bikes and are working their way onto gravel bikes these days as well. With their meteoric rise to becoming a standard part, we now have more great options to choose from than ever before.

　　Our expert testers rounded up nine of the top options available in 2024 and put each model through its paces while assessing important performance characteristics like the smoothness of travel, saddle clamps, installation, adjustability, weight, serviceability, and design.

　　From the ultra-premium wireless RockShox Reverb AXS to the value-packed OneUp Components V3, weve found a dropper to suit every need and budget. To see the specs of all the models we tested at a glance, check out our comparison chart. If you want to learn more about dropper posts, you can refer to our detailed buying advice and price value sections.

　　Editors Note: We refreshed this guide on October 3, 2024, after testing the recently updated versions of the Bike Yoke Revive, Fox Transfer Factory, and Wolf Tooth Resolve dropper posts.

　　The Best Dropper Posts of 2024 Best Overall Dropper Post: Wolf Tooth Resolve rev2 Best Value Dropper Post: OneUp Components V3 Dropper Best Budget Dropper Post: PNW Components Loam Dropper Smoothest Dropper Post: Bike Yoke Revive 3.0 Best Wireless Dropper Post: RockShox Reverb AXS Best Updated Dropper Post: Fox Transfer Factory Best Overall Dropper Post Wolf Tooth Resolve rev2 Specs Available travel Lengths 125, 160, 200, 242 mm Overall Lengths 373, 443, 523, 607 mm Available Diameters 30.9, 31.8, 34.9 mm Size Tested 31.6 x 200 mm travel Measured Weight Post: 565 g (2.82 g/mm travel), Lever: 39 g

　　

　　

　　Pros Relatively lightweight Super smooth Self-bleeding cartridge never develops sag Adjustable travel in 5mm increments to dial in perfect length Short stack height and insertion depths User serviceable all parts available Cons Fairly expensive More sensitive to seatpost clamp torque and air pressure than most Paul Clauss It came as a little bit of a surprise when Wolf Tooth launched its first dropper post back in 2022. Now in its second iteration, the Resolve rev2 gets incremental changes over the original, along with a 242 mm version to take the crown as the longest dropper on the market by a whopping 2 mm margin. What hasnt changed is the exquisite machining, attention to detail, and buttery smooth travel.

　　Other than adding a 242 mm length, Wolf Tooth also expanded its size offerings to include 34.9 mm diameters. All the lengths — 125, 160, 200, and 242 mm — can also have travel reduced in 5 mm increments if needed to get the perfect fit. Internally, Wolf Tooth claims to have improved upon the self-bleeding function, as well as a 25% reduction in lever force for actuation with the Spool Valve. We tested ours with the Wolf Tooth Remote Pro lever ($70), which is a thing of beauty in and of itself.

　　Installing the Resolve rev2 is about as easy as it comes, with the barrel end of the cable attached at the actuator on the bottom of the post. Connecting the cut end of the cable to the Remote Pro lever is a bit fiddlier than most but worth it for the impressively smooth action of the lever and the amount of adjustability it provides. Its worth noting that the Resolve does not come with the Remote Pro, but its a worthy purchase, in our opinion.

　　It takes very little force at the lever to actuate the Resolve, and it drops like a rock beneath the weight of a rider. Its almost disconcerting if youre used to a dropper that requires a little more compression force, like the Fox Transfer, but it makes dropping the saddle super quick and easy. Its also really smooth in both compression and extension — very close to the undisputed king of smoothness, the Bike Yoke Revive 3.0. The self-bleeding feature also works as advertised, keeping the post free of sag, even if you store your bike hanging or upside down. It essentially purges any trapped air out of the system every time you fully drop it.

　　With a 32 mm stack height and relatively short overall and insertion lengths, the Resolve makes it possible for riders to get as much drop as possible on their bikes. If you buy your post directly from Wolf Tooth, you can have them install travel reduction spacers to get the perfect fit for your bike, or you can purchase a spacer kit to do it at home or have your local bike shop take care of it. Wolf Tooths online dropper length calculator is an excellent tool. At 565 grams (31.6 x 200 mm), its also lighter than most other posts on the market, except the OneUp V3.

　　The Resolve rev2 is nearly faultless, but we learned a few things while using it. Adjusting pressure can be a bit frustrating as it loses a bit of air when you disconnect the shock pump, and it is very sensitive to pressure. Its also more sensitive to torque at the seat post clamp, and overtightening it makes the post feel sticky in its travel.

　　With prices ranging from $350 to $396 depending on length, the Resolve rev2 doesnt come cheap, but this post is meant to last a lifetime. Wolf Tooth has made it easily serviceable and offers all of the replacement parts so you can fix any problem that may arise. Heck, you can even switch between 30.9 and 31.6 mm diameters and swap it between bikes if you need to.

　　Pros Still reasonably priced Smoother than previous version Lighter weight lighter than most lightweight posts Very low stack height Six travel lengths and 4 diameters offered Adjustable travel for ideal fit Easy maintenance Cons Slightly more expensive than the V2 New sealed cartridge has fixed return speed Paul Clauss OneUp Components recently updated their popular V2 Dropper and improved upon the previous version in several ways with the excellent new V3 Dropper ($270). The OneUp V2 was already one of the best droppers on the market, especially for the price, but OneUp Components managed to make the new V3 even smoother and significantly lighter weight. It retains most of the hallmarks of the V2, like a short, 30mm stack height, six travel options, adjustable travel with shims, short overall lengths, and easy serviceability, but now it’s one of the lightest droppers on the market, lighter even than some of the “Super-Light” models.

　　The biggest part of the story is the significant weight savings of the V3 dropper — 60-70 grams lighter than the V2 — which was achieved in large part thanks to a move to a new, non-adjustable hydraulic cartridge. This new sealed cartridge has a fixed return speed, and its lack of adjustability means they were able to reduce weight by eliminating the hardware needed for an air valve under the saddle clamp.

　　While some riders may miss the lack of adjustable return speed, we can confirm that the fixed rate is plenty quick, and we didn’t miss it at all. A tiny amount of weight was also saved by machining out unnecessary material from the upper half of the saddle clamp. The 210mm (30.9) version we tested weighed in at just 515 grams, and for the sake of comparison, the 150mm length (31.6 mm) weighs 8 grams less than the Fox Transfer SL in the same size.

　　Taking it even further, the new cartridge has a lighter actuation, so it takes less force at the lever to initiate a drop. The post still drops fast, and it feels even smoother than the previous version. Upgraded bushings have more overlap along with more anti-rotation pins that should help it from developing play side to side or fore/aft play. A brand new wiper seal is also a nice upgrade that should work well to keep grime out and lubricant inside, which were common complaints about the V2.

　　One of the best things about OneUp droppers has always been the incredible size range, with six drop lengths increasing in 30mm increments from 90mm to a whopping 240mm. On top of that, travel adjustment pins (shims) are included to reduce travel in 10mm increments so you can maximize your drop and dial in the fit exactly to your needs. It comes in 30.9mm, 31.6mm, and 34.9mm diameters, as well as 27.2mm (in 90mm and 120mm lengths only). We tested it with OneUp’s V3 Remote ($45), which has a grippy, textured rubber thumb pad, light action, and a short throw.

　　While there are lots of great droppers on the market, the new OneUp V3 is arguably one of best. Yes, at $270, it costs a bit more than the V2, but it’s still reasonably priced, lighter than ever, super smooth, and with a low stack height, adjustable travel, and six travel options to choose from, it will help you get the most drop possible without weighing you down or breaking the bank.

　　$270 at REI$270 at evo$270 at Amazon Best Budget Dropper Post PNW Components Loam Dropper Specs Available travel lengths 125, 150, 170, 200 mm Overall lengths 385, 440, 480, 540 mm Available diameters 30.9, 31.6, 34.9 mm Size tested 31.6, 150 mm travel Measured weight Post: 529 g (3.53 g/mm travel), Lever: 49 g

　　

　　Pros Great performance at an affordable price Easy tool free travel adjust Basic but functional and ergonomic lever Easy to make small adjustments to saddle height Cons Rubber pieces get dirty very easily Taller stack height Paul Clauss Exhibiting reliable, smooth performance and being the lowest-cost post in our test, the PNW Loam Dropper ($199 to $209, depending on length) is easily one of the best values around. With its solid, consistent feel, the PNW Loam post is a great option for most riders looking to upgrade from a stock post, regardless of budget.

　　The setup for the PNW Loam is about as standard as it comes. You install the saddle on the standard two-bolt design, attach the barrel nut, pull the cable through the housing (hopefully already in your frame), connect the cable to the lever, cut/crimp, and go ride. The overall length of the 150mm version is pretty good at 440mm, and the stack height is a reasonable 50mm (compressed) which is a bit taller than some other models we tested. Should you need to reduce the travel for ideal fitment, the Loam features a nifty tool-free travel reduction option. While most people wont use this outside of the initial setup, it is a nice touch that will make fitting for folks right on the edge of the maximum travel length easy and straightforward.

　　The PNW Loam Lever Gen 2 utilizes a replaceable/customizable rubber thumb pad and a larger, rectangular shape. This is a quality remote lever, but we found the position of the lever is slightly less ergonomic than some due to the set angle, even with the three horizontal positioning options. The Loam has a reasonably light action (in line with the OneUp V3 lever but requiring more effort than the Fox Transfer), and the pad color can be customized along with the collar on the post if thats something youre into. Just be careful that your fingers are not covered in grease when you set the post up — especially if you have one of the lighter color pads — as they can get pretty dirty.

　　On the trail, the PNW Loam post fades into the background, exactly as a dropper post should. It works, and it works well. Return speed can be adjusted to dial it how you like, and the moderate compression force needed to lower makes micro-adjustments to saddle height straightforward.

　　At just over $199-209, the on-trail performance of the PNW Loam Dropper post hits above the price point. The Loam should be shortlisted by any riders on a budget who are looking for an affordable and smooth dropper, and chances are you’ll be able to find an option that fits you and your bike.

　　For those with gravel bikes or older bikes with external cable routing, PNW also makes a variety of other models to suit your needs.

　　Pros Smoothest travel on the market Several notable improvements over the Revive 2.0 Adjustable travel in 5 mm increments Triggy Alpha remote is super nice Get rid of sag quickly and easily with Revive valve Cons More expensive Not the lightest but not exactly heavy either 213 mm is longest version Paul Clauss Bike Yoke set a high bar for smoothness and performance with the Revive and Revive 2.0, but there was still room for improvement. The Revive 3.0 ($350 $420) still boasts the hallmark smoothness and unique reset valve that the previous versions were known for, but with some significant changes that address most of our complaints about the 2.0.

　　A couple of the biggest changes for the Revive 3.0 are a new saddle clamp, which reduces the stack height by 5 mm, and a new actuator that trims an additional 10 mm of length at the bottom of the post. Thats a 15 mm reduction in the overall lengths of all sizes and should make it much easier for people to fit the maximum travel possible on their bikes. We struggled with the long actuator on the previous versions, so that update alone is a big hit with us. On top of that, Bike Yoke reversed the orientation of the cable, so installation is now much easier with the barrel end at the actuator and the cut end at the remote.

　　Internally, everything remains about the same, and thats a good thing. Bike Yokes precision engineering and design make the Revive 3.0 the smoothest post weve ever used. Other posts come close, like the Wolf Tooth Resolve rev2 and Fox Transfer, but there is a buttery feel to the compression and extension of the Revive that no other post can quite match. It is truly uncanny just how smooth this post is, and it just feels incredibly refined. Compressing the post takes almost zero effort, and it returns predictably and in a very controlled manner. The user can also adjust the return speed by changing the pressure in the spring — just know that youll need to remove the saddle clamp and use the included valve adapter to do so.

　　The reset valve also remains and works very effectively to quickly purge air out of the system if/when the post develops any sag. With a quick turn of a 4 mm allen key, or the included lever, and compression of the post, everything goes back to functioning normally without needing a deeper service. Bike Yoke also includes four 5 mm spacers with the post so users can reduce travel to optimize the fit. This is a great feature for people squeezing the most travel possible onto their bikes, although the spacer installation process is more involved than most other posts with adjustable travel.

　　We tested it with the Triggy Alpha Long remote and were impressed by the high level of positional adjustability to dial in the ergonomics to your liking. Like the Wolf Tooth Resolve, the Revive 3.0 is also user-serviceable with standard tools, and Bike Yoke offers all of the replacement parts youll ever need. Sure, this post is on the high end of the price spectrum, but itll also last for a very long time if you want it to. You can even swap between 30.9 and 31.6 mm lowers if you ever switch frames and need a different size.

　　Not too long ago, the 213 mm Revive was the longest dropper on the market. Several brands now offer posts in the 240 mm range, but 213 mm is the longest you can get in the Revive, which means that tall riders may end up looking elsewhere. And, while 633 grams (31.6 x 213 mm) is by no means egregiously heavy, it is notably heftier than similar-sized posts from OneUp and Wolf Tooth.

　　Regardless, the Bike Yoke Revive 3.0 should be seen as a long-term investment in performance and functionality. Like its predecessors, this post is ultra-smooth, very well made, and the recent updates make it easier to fit and install.

　　Pros Great lever ergonomics and easy actuation Precision control Super-easy post and seat installation Quick return speed Electronic No cable or hose Cons Very expensive Heavier weight Electronic — need to remember to charge battery Higher stack height with large collar 170 mm is longest length Paul Clauss The RockShox Reverb AXS ($861) is the electronic version of RockShoxs longstanding Reverb dropper post. It was one of the first electric droppers on the market, and while it is very expensive, it is arguably one of the best droppers available. It isnt plagued by any of the issues of the hydraulically-actuated version, like temperature sensitivity and more challenging installation (due to hydraulic fluid in the hose and remote), and it works impressively well.

　　The Reverb AXS comes in 30.9, 31.6, and 34.9 mm diameters as well as 27.2 mm in the Reverb XPLR AXS thats made for gravel bikes. The larger diameters all come in 100, 125, 150, and 170 mm drop lengths which should work for most people. Unfortunately, for the long-legged folks, it does not come in a 200 mm length.

　　The overall lengths are fairly reasonable, but it does have a taller stack height of 62 mm (compressed) as a result of the taller silver collar and the motor/battery housing at the top of the post. It is also one of the heavier options, with a measured weight of 655 grams (150 mm length) for the post and 54 grams for the remote. For comparison, that is 180 grams heavier than the OneUp V3 and remote in the same drop length (not counting cable and housing).

　　Given the lack of cables and/or hoses, setting up the Reverb AXS couldnt be any easier. Simply insert the post into the seat tube, attach the remote to the handlebar, charge the AXS battery (takes about an hour), and then pair the two together (like pairing to a Bluetooth speaker). Attaching the saddle is super quick and easy, too, with a single T25 bolt to clamp the saddle rails as well as a super user-friendly tilt adjustment.

　　The battery locks securely and firmly into place at the back of the post. Pressing a button on the post shows battery life, and it lasts a surprisingly long time. During testing, it was 42 hours of ride time (according to Strava) before the battery indicator turned red. The Reverb AXS remote uses a CR2032 watch battery, which SRAM says should last over two years, and it is cheap to replace (less than $10 for any two-pack). You can also use the SRAM AXS app to see battery percentages for both the post and remote.

　　Electronics aside, the Reverb AXS remote is quite different from any cable-actuated post remote. It is ergonomic, sits close to the bars, and has extremely quick action. Instead of pushing a lever to pull a cable, it is essentially just a light press of a button. Your thumb barely needs to move, and while it takes a few minutes to get used to, it makes regular remote levers seem archaic pretty quickly.

　　The AXS remote, combined with the quick action of the post, provides an incredibly precise feel on the trail. For the post to continue dropping, you need to keep your thumb on the lever, so a quick tap on the lever won’t drop the post the entire way but does make it super easy to micro-adjust the saddle height. Because of the light action and ease of dropping 5-15 mm with a quick tap, we found ourselves making those smaller adjustments notably more than with other posts.

　　The Reverb AXS has one of the fastest return speeds among the models we tested (second to the Fox Transfer SL), topping out audibly but not excessively hard. It isnt adjustable, but for those who like a quick return speed, it will be just right. The overall action is quite smooth but requires moderate force to compress compared to some other models.

　　The Reverb AXS includes SRAMs “Vent Valve” to remove air from the internals located at the bottom of the post, which is easy enough to access with no cables to speak of. Our test post has not developed any squishiness at all, but the relief/vent valve is a good feature to have to avoid more complex maintenance. Ours has worked flawlessly through the test period, however.

　　Should you buy an $861 seatpost? Thats entirely up to you and how much disposable income you have. That said, if you have the means, we think its one of the best droppers available and doubt youll be disappointed by the performance and quick, precise feel of the RockShox Reverb AXS. It is often sold without a remote now as well to pair with Srams Transmission pods, so be sure to doublecheck when buying.

　　Pros A major improvement over the previous version Smooth travel Adjustable air spring/return rate Damped feel at bottom of stroke Can reduce travel in 5 mm increments Cons Heavier weight Long actuator and longer overall lengths may limit fitment for some Paul Clauss Fox recently updated its Transfer dropper posts, making a number of notable improvements in the process. While the previous version was good, the 2025 models are significantly better, and a huge step up in the performance, fit, size options, and adjustability. We tested the latest Fox Transfer Factory ($339) and came away quite impressed. It also comes in a Performance Elite version with a black stanchion that goes for $289.

　　Fox put some serious effort into addressing the shortcomings of the previous generation of Transfer droppers. With the 2025 models, they increased the number of drop lengths with 5 options between 120 and 240 mm — increasing in 30 mm increments. Travel can also be reduced in 5 mm increments with included plastic spacers. They also added 34.9 mm diameter sizes along with the 30.9 and 31.6 mm options. Stack height was reduced from 40 to 35 mm by using a smaller collar which helped shorten the overall length of the posts by a little bit as well. A new head design and seat clamp does away with the pivoting hardware in favor of a tried and true two-bolt system. Inside, an adjustable air spring replaces the nitrogen-charged cartridge for easier changes to air pressure.

　　Installing the Transfer is quick and easy, and we paired ours with Foxs 1x remote lever. Attaching the saddle to the new seat clamp is a bit fiddly, but unless you swap saddles regularly, its pretty much a one-time deal. That said, the Schrader valve for the air spring sits underneath it at the head of the post, so if/when you want to adjust the pressure, you may need to remove it. We ran the post at the factory pressure and found it to be pretty much perfect.

　　The Fox 1x remote has a relatively light action, and it takes very little effort to push it and actuate the post. We found compression and extension to feel ultra-smooth and easy to control. As you reach the bottom of the travel when compressing the post, it has a unique damped feel and doesnt bottom out hard the way other posts can. It feels a bit odd at first and takes a tiny bit more effort to slam it down, but you get used it pretty quickly.

　　Unlike older models of Transfer posts, which suffered from a bit of side-to-side play, the latest version is super tight and stable — no more saddle rattle over rough sections of trail. Weights have also come down a bit, but at 667 grams (31.6 x 210 mm), its still a bit heftier than the Wolf Tooth or OneUp droppers in comparable sizes. And, while the stack height and overall lengths have also been reduced, its still a tad longer than either of those posts, too.

　　Still, the new Fox Transfer Factory performs flawlessly on the trail and is arguably one of the best droppers on the market. Not only is it better, but at $339, the price has come down a bit, too. Unless youre counting grams, the slightly higher weight will likely go unnoticed, but that Kashima-gold bling certainly wont.

　　Pros Fast return speed Smooth, controlled action Quite light Tech climb” feature went unnoticed (in a good way) Cons Max travel of 125 mm Longer overall length and stack height Weight is low, but weight per mm/travel is higher than other SL model tested Paul Clauss The Bike Yoke Divine SL ($320) is the German brands top-of-the-line XC dropper. Weighing in at 451 grams for the post, the Divine SL is lightweight and will save some grams compared to most trail/enduro options. Given its XC focus, it is only currently offered in shorter drop lengths of 80, 100, and 125 mm.

　　Setting up the Divine SL is straightforward but does require the plastic sleeve tool included with the post to attach the cable nut assembly at the bottom of the post. This takes a few minutes longer than the direct cable end connection on most posts but is very straightforward and poses no difficulties just don’t lose the plastic tool to remove and attach the cable nut inside the bottom of the post tube or the nut and plastic plunger piece!

　　The Divine SL has what Bike Yoke calls the Tech-Climb feature, which adds a small amount of suspension action to the post, but only when it is in a middle position fully extended or dropped are still locked. While this seems like an interesting feature, it managed to go completely unnoticed and didnt seem to impact its performance either positively or negatively. Pressing on it by hand, you can feel about ½ to 1 cm of motion, and perhaps not noticing it while riding could be considered a success.

　　Bike Yoke does say that reducing the air pressure in the post will increase the action of the Tech-Climb feature, but even when lowered to 250 psi, it didnt seem to change the action much. Like the Revive 3.0, accessing the air valve at the top of the post to adjust pressure does require the use of the included adapter.

　　The Divine SL shares some of its internals with the Revive 3.0, and it is similarly smooth in its action. It doesn’t have the reset feature, but Bike Yoke says it is designed to fully reset the hydraulic system with every full drop, much like the Wolf Tooth Resolve, and we never experienced squishiness or noticeable play. The micro-adjustability and smoothness were not quite as strong as the Revive 3.0 or Fox Transfer (non-SL version), but still near the top of the class for the posts in this test.

　　With a max travel of 125 mm, the Divine SL probably wont be on everyones shortlist, but it is a strong contender for riders looking for a shorter travel, lightweight XC dropper post. The Bike Yoke Divine SL is very smooth, quick, snappy, and lightweight, making it a great choice for XC riders looking to add an infinitely adjustable, high-performance dropper to their lightweight rigs.

　　Pros Very smooth travel Easy to use pivoting bolt seat clamp Easily user serviceable (everything but the cartridge) with very standard tools Easy install Cons Slower, fixed compression and extension speed Longer overall length and stack height Heavier weight Paul Clauss The Crankbrothers Highline 7 ($300) sits directly in the center of the price range for the cable-actuated posts in this review. For a slight premium over some lesser-priced competitors, it performs exceptionally smoothly, features an easy-to-use pivoting bolt seat clamp, and everything except the cartridge is serviceable with very standard tools. It does have a longer stack height and overall length and fixed compression/extension speed, but the Highline 7 is a solid mid-range option for riders looking for smooth, controlled action in a post they’ll be able to pull apart and keep running for quite a while.

　　The Highline 7 comes in both the standard 30.9 and 31.6 mm diameters and 100, 125, 150, 170, and 200 mm drop lengths. The overall lengths and stack height are a little bit longer than most other models we tested, so that is something to bear in mind depending on your frame. For anyone with smaller seat tube diameters on gravel or XC bikes, Crankbrothers also makes the Highline XC Gravel in a 27.2 mm diameter that comes in 60, 80, 100, and 125 mm lengths. Crankbrothers also makes the affordable Highline 3 dropper that retails for just $200.

　　Setting up the Highline 7 is very easy you don’t even need a barrel for the end of the cable as it connects directly. We did not test the Crankbrothers Highline Remote, so we cant comment on it. Instead, we tested it with the Wolf Tooth ReMote Pro, which posed no problems. The rear bolt of the seat clamp pivots, making saddle installation easier than a standard 2-bolt design.

　　On the trail, the Highline 7 is reliable and has a very consistent, smooth feel in both compression and extension. It isnt adjustable and the fixed rate is a touch slower than other posts like the BikeYoke Revive, Fox Transfer, PNW Loam, or OneUp V3, and it has a less audible top-out. While it isnt too slow, necessarily, some may find themselves wanting the ability to speed it up.

　　Even with the slower speed, the Highline 7 is super smooth. It is fully user-serviceable with very standard tools, and quality components like Trelleborg seals and IGUS LL glide bearings and keys are included, so it should be easy to maintain the smooth feel for the lifetime of the post.

　　While the longer stack height and overall length, combined with the slightly slow compression and extension speeds, didnt make it stand out compared to the best, we think most riders who can make the fit work and are looking for a serviceable, smooth, controlled, and reasonably priced post will be very happy with the Crankbrothers Highline 7.

To achieve such light weight, the Transfer SL uses a much simpler mechanical spring (as opposed to a hydraulic cartridge), that only stops in two positions, fully up or fully down. Weighing only 441 grams for the 150mm travel option tested (less than 3 grams per mm travel), the Transfer SL is a good option for XC, gravel, or particularly weight-conscious riders, provided they get along with the two-position approach.

　　Given the lightweight focus of the Transfer SL and the intended audience of cross-country and gravel riders, it comes in sizes that line up with the bikes its designed to be used on. In the 30.9 and 31.6 mm diameter, it comes in 75 and 100 mm drop lengths. In the 31.6 mm diameter, it also comes in 125 and 150 mm lengths for weight-conscious trail riders.

　　For those riding bikes with 27.2 mm seat tube diameters, the Transfer SL 27.2 is available with 50 or 70 mm of drop. In addition to the Factory version we tested, the Transfer SL Performance Elite skips the Kashima stanchion and retails for $329. Likewise, the Transfer SL 27.2 comes in the same configurations at the same prices.

　　Setting up the Fox Transfer SL involves clamping the cable end in the cutout at the bottom of the post and running it through the plastic end cap, which was comparably easy to the standard barrel at the cable end used in most of the droppers tested. Unlike the BikeYoke Divine SL, the Transfer SL cannot be cut down to reduce the overall length/weight, and it has the longest overall length of any post in the test at 485 mm for 150 mm of drop (17 mm longer than the Crankbrothers Highline 7). This shouldn’t pose too much of an issue on most XC frames but it is longer than average and should definitely be noted depending on the insertion length on your frame.

　　We tested the Transfer SL with Fox’s Transfer 1x Remote. It’s a simple lever, but it works well with light actuation force and good ergonomics. Fox does offer a drop bar compatible lever for $55 for gravel riders who want a short travel post. 

　　While riding, the mechanical spring gives the Transfer SL the fastest return and drop speed of any post in the test. The spring only works to extend the post and doesnt support the riders weight. It is so easy to drop that it feels like the floor is falling out from underneath you. It is impressively smooth, but the drop speed takes some getting used to, as does the fact that it will come back up to full extension if you dont lower it all the way down.

　　If you like to ride with your saddle in any position other than fully up or down, the inability to stop it anywhere in its travel will surely be missed. It is also worth noting that the two-position nature of the Transfer SL is not super visible in Fox’s marketing materials, but it is something that prospective buyers should definitely be aware of.

　　Fox claims that most XC and gravel riders surveyed ride mainly with their posts in a fully extended or compressed position, and the Transfer SL Factory is a well-performing, quite snappy option if you do the same. This post is lightweight and sure to help you keep the weight of your race rig or gravel bike as low as possible while still enjoying the benefits of a dropper post.

How We Tested Dropper Posts Its fair to say that the team at GearJunkie is obsessed with all things outdoor-related, and that includes mountain biking. This is especially true of products like dropper posts that enhance our riding experience and performance out on the trail.

　　While there were some reservations about adopting this new-fangled technology when they initially came out, youll find droppers on virtually all of our mountain bikes and even some of our gravel bikes these days. And weve tried a lot of them. Whether for product launches, individual reviews, or on test bikes, weve had the chance to try nearly every model on the market.

　　

　　Our testers have been using dropper posts since they hit the market. Review co-author Jeremy Benson has tested over 15 different models; (photo/Jeff Schertz) Our Expert Testers For the purposes of this buyers guide, we rounded up nine of the best dropper posts available in 2024 to test and compare. Review author Paul Clauss spent months testing these posts in a wide range of weather conditions on technical northern Vermont trails that require lots of raising and lowering of the saddle. A mechanical engineer by trade and a skilled bike mechanic, Paul enjoys scrutinizing different designs, tinkering with adjustments, and is adept at differentiating subtle performance differences in the workshop and out on the trail.

　　Paul has an affinity for technical features and rock slabs, and fortunately, the terrain near his home in northern Vermont is an ideal testing ground for dropper posts with plenty of ups, downs, and rocky, rooty challenges that require frequent changes to saddle height. In addition to testing dropper posts, Paul has also contributed to our best mountain bike flat pedals and mountain bike flat pedal shoe reviews, along with bike repair stands and bike pumps.

　　GearJunkie editor Jeremy Benson also contributed to this guide. Benson has been testing and reviewing bikes, accessories, and components for 8 years and has personally tested more than twelve different dropper posts. As an obsessive rider and racer, hes always seeking out the highest-performance products he can find and appreciates components that make his bike as light as possible.

　　Hes also experienced the evolution of dropper posts firsthand and recognizes that virtually every dropper on the market is much better than any options we had a decade ago. Some of the other guides that Benson has contributed to include mountain bike shoes, mountain bike shorts, mountain bike helmets, and hitch bike racks.

　　Our Testing Process After weighing each post and remote for consistency and comparison to the manufacturers specs, Paul and Jeremy installed them on one of their several mountain bikes. Installing each post ourselves gave us the opportunity to assess the relative difficulty of doing it on your own, and provided valuable insight into the saddle clamps and remote levers. It also gave us the opportunity to assess fitment-related concerns when installing — and choosing the right size to begin with.

　　Once each post was installed, we performed numerous hand tests in the workshop to compare the smoothness of travel and return speeds. We made any necessary adjustments and then took to the trails. On the trail, Paul and Jeremy both focused on key performance attributes like actuation force at the lever, compression force, return speed, and smoothness while making frequent adjustments to saddle height. From the technical trails of Vermont to the rough and dusty trails of the Lake Tahoe region, these posts were ridden hard to determine their relative strengths and weaknesses. Paul and Jeremy also switched between posts often for more direct comparison in their efforts to find the best dropper posts.

　　

　　When your saddle is low, you can move around the bike more freely for greater control; (photo/Heather Benson) How to Size a Dropper Post for You and Your Bike When purchasing a new dropper post, the fit for you and your bike is your first priority. Not only does it need to fit your frame to be compatible, but you want it to suit your body size and needs as well.

　　Seat Tube Diameter This is one of the easiest steps — just make sure you select a post that matches the seat tube diameter of your frame. Most modern mountain bikes have 30.9 mm or 31.6 mm seat tubes, and dropper post manufacturers often provide options for less standard options like 27.2 mm (for gravel and some XC frames) or 34.9 mm diameters. If you are unsure of your seat tube diameter, you can typically find it printed on the seat post that is currently on your bike, or you can look it up on the manufacturers website. While you should be able to find a post that matches your seat tube diameter, you can sometimes purchase a smaller one and shim the seat tube in a pinch.

　　

　　Most posts with adjustable air springs have a valve under the saddle clamp where you can change the pressure, like the new Fox Transfer Factory seen here; (photo/Jeremy Benson) Infinitely Adjustable vs. Fixed Interval Travel The vast majority of dropper posts feature what is called infinitely adjustable travel, meaning they can be adjusted anywhere within the available travel range between full compression and full extension. While it is most common to ride with the post all the way up or all the way down, there are plenty of circumstances where dropping the post just a little bit is ideal, and infinitely adjustable posts allow you to do so.

　　A few posts on the market have fixed interval travel, meaning they stop only at certain spots within their travel range. Typically, this style of post uses a simpler mechanical spring to control the travel. The only post we tested that adjusts at fixed intervals is the lightweight Fox Transfer SL, which stops in only two positions, fully compressed and fully extended.

　　Internal vs External Routing Most modern mountain bikes are designed to be used with dropper posts and usually feature internal cable routing. Consequently, most droppers are also designed to be used with bikes that have internal cable routing. The actuator where the cable connects is at the bottom of the post inside the frame. All of the droppers we tested are made for internal cable routing, other than the RockShox Reverb AXS, which is wireless.

　　Many older bike frames and some gravel bikes do not have ports for internal cable routing. Thankfully, there are some externally routed droppers on the market, though they are less common. PNW components make several models of externally routed droppers, and you can often find similar options from Brand-X and PRO if you look around.

　　

　　Many posts have travel reduction features that allow users to fine-tune the travel to optimize fit on the bike. The PNW Loams system is tool-free; (photo/Paul Clauss) Travel Reduction Some posts allow you to decrease the maximum post travel, ensuring you can get the maximum drop available for your bike. For example, on the bike used for testing with a stack height of 260 mm and maximum seat tube insertion of 210 mm, the OneUp size calculator shows the maximum drop for my setup as 170 mm, achieved by reducing the travel of their 180 mm post by 10 mm.

　　The PNW Loam Dropper uses a tool-free system to decrease the maximum travel by up to -25 mm (in 5 mm increments) with a built-in nylon shim. The OneUp V3 Dropper uses a similar system but limits travel adjustment to 10 or 20 mm and uses pins and guide slots rather than a nylon shim. The Bike Yoke Revive 3.0 also allows up to 20 mm of travel adjustment, but the installation process is a little more involved.

　　Similarly, the Wolf Tooth Resolve rev2 can have maximum travel reduced, and they will install spacers for you when you order the post, or you can purchase travel reduction shims after the fact and install them yourself or bring your post to a shop to have it done for you.

　　

　　Most saddle clamps are fairly simple two-bolt designs that secure the saddle rails and generally go unnoticed. Wolf Tooths clamp on the Resolve rev2 has the bolts angled nicely so that its easier to get tools on them when needed; (photo/Jeremy Benson) Saddle Clamp The saddle clamp at the seatpost head is where your saddle rails attach to the seatpost. Good saddle clamps are quiet, stay at the appropriate torque, and make saddle installation/removal reasonably easy. Most of the posts in this test used a standard two-bolt head design to adjust saddle angle and fore/aft position. A few models have clamp designs that help make the installation and removal process slightly easier.

　　The Crankbrothers Highline 7 has hardware that swivels, while the OneUp V3 dropper has slotted plates. Though we dont typically install/remove our saddles frequently, these seemingly trivial design features are really quite helpful when testing dropper posts back to back.

　　

　　With smooth action and loads of adjustability, Wolf Tooths Remote Pro dropper lever is one of the best on the market; (photo/Jeremy Benson Remote Levers Every dropper post uses a remote to actuate the travel up and down. While many posts used to come with a lever, most posts are sold without one these days, meaning you can usually choose whatever remote you like. Most levers for cable-actuated dropper posts (that clamp the free cable end at the lever) are compatible with any post, allowing you to choose the lever that works best with your ergonomics and cockpit setup.

　　The advent and proliferation of 1x drivetrains freed up some space on the left side of the handlebar where the front derailleur shifter used to be, so the majority of dropper remotes are 1x levers that resemble a shifter paddle that you press with your left thumb. Examples of 1x remote levers include the Wolf Tooth Remote Pro, Fox Transfer 1x Remote, Bike Yoke Triggy Alpha, PNW Loam Lever, and OneUp V3 Lever.

　　Many have textured metal surfaces to provide thumb traction, while some use replaceable rubber pads for grip. Additionally, some brands give you color options to customize your ride. For example, Wolf Tooth sells its machined aluminum remote levers in a range of anodized colors. Similarly, PNW and OneUp Components sell their rubber thumb traction pads in various colors, too.

　　

　　Installing a dropper post may seem daunting, but it isnt too hard to do on your own if you follow the instructions and have the right tools for the job. The hardest part is typically routing the cable housing through your frame; (photo/Jeremy Benson) Installation If you purchase a new dropper from a bike shop, it is common that they will install it for you. If you purchase a dropper from an online retailer, you can bring it to a local shop and pay to have it installed. If you like wrenching on your own bike, doing it yourself is relatively straightforward, assuming you have cable/housing cutters and reasonable mechanic skills. A quality repair stand doesnt hurt, either.

　　The installation process is largely the same regardless of the actuation method. Most brands have detailed instructions and/or instructional videos to guide you through the process.

　　Run a section of cable housing (or hydraulic line) from the seat tube to the exit port near the head tube. Which way you pull the housing through can depend on your frame, and it is always a good idea to use existing housing to pull through new housing whenever possible — this helps guide the new housing through tight curves in the internal routing. Attach the cable to the actuator at the bottom of the post and run it through the housing. Position the housing in the housing stop at the base of the post Push the post into the frame while simultaneously pulling the cable/housing (or hydraulic line) out of the exit port near the head tube. Attach the cable/housing to the lever after mounting it to the handlebars. For posts with hydraulic actuation, bleed the system. For cable-actuated posts, clamp the cable to the lever, trim the cable, add a cable end, and use the barrel adjuster to achieve proper cable tension. Maintenance Similar to moving suspension parts, most dropper post manufacturers recommend cleaning, inspecting, and lubricating your post after every ride and performing their version of a full service between 100 and 200 hours of riding. Many posts are designed to be user-serviceable, and they can be taken apart, cleaned, and relubricated with standard tools and a little time. Parts for many posts are available for purchase, and this can save you money while keeping your dropper working well in the long term.

　　

　　Droppers on gravel bikes can be great depending on where and how you ride your drop bar bike; (photo/Heather Benson) Price Value Dropper posts are almost always more expensive than rigid posts, but considering the performance benefits they provide, we feel they are worth their weight in gold. Like anything in mountain biking, we have quite a few options, and they come at a pretty wide range of prices. Thankfully, most modern mountain bikes come with dropper posts, but many people choose to upgrade to something that works or fits better than the stock option. So, how much should you spend, and whats the difference?

　　Note: Most aftermarket dropper posts do not come with a remote lever. Most dropper posts will work with most dropper levers, so if you already have one, you might be able to use it with whatever post you choose. That said, not all dropper post remotes are created equal, and some simply work, feel, and look better than others. When purchasing a new post, you may also need to factor in the cost of a new remote lever into the equation. They typically cost between $40 and $70, depending on the brand/model.

　　Budget These days, you can get a functional dropper for around $150, but we think most people adding an aftermarket post to their bike should expect to spend about $200. Its not that less expensive droppers dont work, but based on our experience, we think you get a higher level of performance and durability by spending just a little bit more.

　　For those operating on a budget, the least expensive model in this guide, the PNW Loam, will set you back around or just over $200 (plus a bit more for a remote if you dont already have one). This post doesnt reinvent the wheel, but it performs very well and is an exceptional value for anyone who doesnt have more to spend.

　　

　　OneUps V3 dropper is reasonably priced and high performance; (photo/Heather Benson) Mid-Tier Moving just a bit higher in the price range, we think most people will find the best ratio of price and performance in the $270 to $400 range. We realize thats a pretty big spread, but thats also where most of the best dropper posts on the market land on the price spectrum. Here we often find smoother travel, lighter weights, and special features that set some models apart.

　　At the lower end of this range, the $270 OneUp V3 Dropper is super smooth, has a short stack height and short overall length, comes in the most drop length options, and is one of the lightest models on the market. The OneUp V3s combination of performance attributes makes it one of our absolute favorites and arguably the best value you can find.

　　As prices climb, we start to see features like the fancy Kashima-coated stanchion on the Fox Transfer Factory ($339), the bleed valve on the Bike Yoke Revive 3.0 ($350 $400), or the self-bleeding cartridge on the Wolf Tooth Resolve rev2 ($350 $396). Generally speaking, we also see an increase in smoothness and quality, and these posts are meant to be user-serviceable and provide many years of faithful service. Most brands also sell small parts so at-home mechanics can keep them running smoothly without needing to shell out more cash to get it repaired at a shop.

　　

　　Wireless posts like the RockShox Reverb AXS often come specd on high-end builds like this $14,000 Yeti ASR; (photo/Heather Benson) Premium Above the mid-tier price range, the cost of dropper posts jumps way up to more than $800. There are only a small handful of models way up here in the price stratosphere, with much higher costs associated with wireless technology. RockShox was the first to market with the wireless Reverb AXS ($861) dropper, and it made a very big splash both in terms of price and a major advancement in wireless technology on mountain bikes. It also happens to work very, very well, albeit a tad heavier than wired options.

　　Fox arrived a bit later to the wireless dropper post party but has developed its own wireless protocol in an attempt to gain the upper hand. Launched in the summer of 2024, the Fox Transfer Neo ($839) was the brands first wireless component — and a sure sign they are developing many more — and it functions similarly to the Reverb AXS. We havent tested Foxs wireless post yet, but we hope to get our hands on one in the near future.

　　Does anyone actually need a wireless dropper on their bike? Absolutely not. Is it cool that we have the option? We think so. Still, unless youre swimming in disposable income, we think the added cost of upgrading to wireless is hard to justify when less expensive options perform just as well (but with cables).

　　

　　Dropper posts allow us to ride harder and more efficiently with our saddles at the appropriate height for the situation; (photo/Heather Benson) Frequently Asked Questions Do I need a dropper post on my mountain bike? Mountain bikes can certainly be ridden without a dropper post, and for many years we didnt even have the option. While many riders were slow to adopt this new technology due to weight and reliability concerns with early models, they have since become ubiquitous on most bikes for many reasons.

　　Over the past decade, dropper posts have become lighter, more reliable, and more durable. The ability to raise and lower your seat for the terrain in front of you allows you to always have the appropriate saddle height, whether you are riding up or downhill. Adjusting saddle height on the fly makes it easier to move about the bike and move the bike beneath you, resulting in greater control.

　　While some posts are quite expensive, there are also more affordable options that work very well. Price is less of a limiting factor than it once was.

　　So, yes, unless you are an elite-level XC racer who is trying to have the lightest bike possible — and may opt for a lighter rigid post — you should absolutely be riding with a dropper post on your mountain bike. The performance benefits far outweigh the weight penalty of adding one to your bike.

　　Is it bad to leave my post compressed? Leaving your bikes dropper post compressed for an extended period of time is not recommended. When the dropper post is compressed, the internal air pressure is increased, which can put additional stress on the internal components of the dropper post, potentially leading to premature wear and failure.

　　Additionally, leaving your dropper post compressed can cause the hydraulic fluid to become trapped on one side of the post, which can affect its performance the next time you use it. This could lead to damage to the seals and other internal components over time.

　　To maximize the lifespan and performance of your post, its best to store it in the fully extended position when not in use. This will help to ensure that the internal components are not subjected to unnecessary stress or pressure and that the hydraulic fluid is distributed evenly throughout the post.

　　Thats not to say you shoudnt leave your dropper post compressed for shorter periods of time. For example, we often travel with our bikes on hitch bike racks for many hours at a time with our droppers compressed to keep the bikes from interfering with each other. Weve never had any issues.

　　Can I hang my bike by the dropper post or clamp it in a work stand? Its generally not recommended to hang your bike by the dropper post for extended periods of time, as this can put excessive stress on the internal components of the post and potentially cause damage.

　　While clamping to the dropper post stanchion in a bike repair stand is not ideal, and some manufacturers recommend against it because it is possible to crush the stanchion tube with clamping pressure, weve had no issues doing so consistently for short periods of time with any post.

　　You will, however, want to clamp lightly and wrap the post in a rag or use rubber jaws to avoid scratching the dropper post stanchion. Like with suspension components, scratches on the dropper post stanchion can cause premature wear on seals and introduce dirt and dust into the dropper internals.

　　Can I drill a hole in my seat tube to fit an internally routed dropper? Drilling a hole in a frame without internal dropper post cable routing is not recommended and will definitely void any warranties on your frame. It may also compromise the structural integrity of the frame, which could cause serious injury. If you have a frame without internal routing, purchase a post with external cable routing.

　　Externally routed droppers are less common, but there are several models on the market to fit bikes without internal dropper routing. On some hardtail frames, you MAY be able to route cable housing through the seat tube water bottle mounts, but this can be quite tricky.
