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.

　　If youre looking for a new dropper post for your bike, we can help! We rounded up nine of the top options available in 2024 to test and compare side by side. Over the course of several months, we put each model in this review through its paces while assessing important performance characteristics like the smoothness of travel, saddle clamps, installation, adjustability, weight, serviceability, and design. When possible, we also tested each post with its own brands remote to see how they work together.

　　Our top recommendations are listed below, followed by the best of the rest which are also great options to be considered. To see the specs of all the models we tested at a glance, check out our comparison chart. If you need help deciding what you need or how to find a dropper post that fits you and your bike, you can refer to our detailed buying advice and FAQ section.

　　The Best Dropper Posts of 2024 Best Overall Dropper Post: OneUp Components V3 Dropper Best Budget Dropper Post: PNW Components Loam Dropper Runner-Up Best Dropper Post: Wolf Tooth Resolve Smoothest Dropper Post: Bike Yoke Revive 2.0 Best High-End Dropper Post: RockShox Reverb AXS Best SL Dropper Post: Bike Yoke Divine SL Best Overall Dropper Post OneUp Components V3 Dropper Specs Available Travel Lengths 90, 120, 150, 180, 210, 240mm Overall Lengths 295, 350, 415, 480, 545, 610mm Available Diameters 30.9, 31.6, 34.9mm (also a 27.2mm option in 90mm and 120mm lengths) Size Tested 30.9, 210mm travel Measured Weight Post: 515g (2.45g/mm travel), Lever: 42g

　　

　　

　　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 Remote costs extra but thats pretty standard 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 new 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) 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, and 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 the 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, 200mm Overall lengths 385, 440, 480, 540mm Available diameters 30.9, 31.6, 34.9mm Size tested 31.6, 150mm travel Measured weight Post: 529g (3.53 g/mm travel), Lever: 49g

　　

　　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 Paul Clauss Exhibiting reliable, smooth performance and as 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 your 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 (in line with the Wolftooth Resolve 160 (which has 10mm more travel) and Fox Transfer 150, though about 20mm longer than the OneUp V3 150), 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 like the bright orange we tested.

　　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 well 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. If you’re on the fence about upgrading your post, the PNW Loam is a top option that significantly outperforms its low price. For those with gravel bikes or older bikes with external cable routing, PNW also makes a variety of other models to suit your needs.

　　$199 at evo$199 at AmazonCheck Price at Backcountry Runner-Up Best Dropper Post Wolf Tooth Resolve Specs Available travel lengths 125, 160, 200mm Overall lengths 373.2, 443.2, 523.2mm Available diameters 30.9, 31.6 Size tested 31.6, 160mm travel Measured weight Post: 514g (3.21g/mm travel), Lever: 47g

　　

　　Pros Short overall length and stack height Self-bleeding cartridge should promote reliability Can order with travel spacers installed Remote Pro lever is excellent Easy saddle installation Fully user serviceable Lightweight Cons Initial stickiness, resolved with Slick Honey on the stanchion as advised by Wolf Tooth. Higher price point Paul Clauss The Wolf Tooth Resolve ($365 $380) is a relatively new dropper model from Wolf Tooth Components. It features a short overall length and low stack height, a self-bleeding cartridge, the option to buy with travel-reducing spacers installed, and a sensible seat clamp design. It is one of the best models on the market. After addressing some initial stickiness, our test post performed reliably and smoothly with light action, quick return speed, and a good feel when making small changes to saddle height. This performance is enhanced when paired with the beautifully machined Wolf Tooth Remote Pro lever, which is one of the best available. At 514 grams for the post in the 160mm length, the Resolve is also one of the lightest posts around outside of the super-light XC posts (the Fox Transfer SL and BikeYoke Divine SL).

　　Installing the Resolve is a snap and easier to fit in most frames with the short overall length/stack height, and attaching the saddle is very easy with the bottom of the seat clamp attached to the post. This feature makes the two-bolt design much easier to use than the two-piece (top and bottom) standard. The visual seat angle reference is also always a welcome touch. It comes in three travel lengths, 125, 160, and 200mm, and it can be shimmed to reduce travel for fitment purposes. Wolf Tooth will pre-install shims for you in 5mm increments (or you can order them to do it yourself or bring it into your local shop) so you can maximize your drop on your specific frame. Additionally, the post is fully self-serviceable (with the right tools and good mechanic skills), and every part is available from Wolf Tooth. You can even swap the lower portion of the post for a different diameter if you ever change bikes and need a different size.

　　The first impression of the Resolve wasnt perfect, with some sticking near the top of the stroke. After troubleshooting seat clamp tension and air pressure, we reached out to Wolf Tooth for assistance. They suggested cleaning the stanchion with alcohol and lightly greasing it with suspension grease (we used Slick Honey). After this, the post returned to normal function and was smooth throughout its travel, always went to full extension, and continued working well for the duration of testing, even through weeks of super wet and muddy conditions. In terms of micro-adjustability and smoothness, the Wolf Tooth Resolve is solid not as quite smooth, predictable, and precise as the Fox Transfer or BikeYoke Revive, but similar in feel to the Crankbrothers Highline 7. It does require a bit more compression force than some, but nothing excessive and it may actually contribute to the ability to make small, precise adjustments, especially while climbing. The self-bleeding feature also means that it should never develop sag over time.

　　The Remote Pro lever is a standout on its own, with three horizontal mounting options, the ability to adjust the start angle, and short throw/light action, making it easy to find the perfect ergonomics. The medium-sized paddle is easy to find, there are no sharp edges, and the machined texture provides traction with or without gloves in all weather conditions.  

　　The Wolf Tooth Resolve is a great post that performs solidly and sports an exceptionally smart design, low stack height/overall lengths, an easy-to-use clamp design, and self bleeding cartridge. If you are looking for a user-serviceable, reliable, relatively smooth, and easy-to-install option, the Resolve should be on your list. And, riders using any post should certainly consider the Remote Pro when considering any lever upgrades.

　　$365 at REICheck Price at Wolf Tooth Components Smoothest Dropper Post Bike Yoke Revive 2.0 Specs Available travel lengths 125, 160, 185, 213mm Overall lengths 397, 467, 517, 582mm (including actuator) Available diameters 30.9, 31.6 (Revive Max 34.9 and Revive 27.2 also available) Size tested 31.6, 160mm travel Measured weight Post: 536g (3.35 g/mm travel), Lever: 45g

　　

　　Pros Incredibly smooth Very easy to make small adjustments precisely Reset Valve is nice to have, particularly if you hang your bike upside down Cons Relatively long overall length/stack height Expensive Paul Clauss The Bike Yoke Revive 2.0 ($350 to $410 depending on length) uses a unique, non-IFP (internal floating piston) design, as well as a Revive Valve to keep the post going up and down smoothly by allowing excess air to bleed into the shaft instead of into the oil. It also performs flawlessly and is one of the smoothest and most intuitive posts on the market, losing a tiny bit to the competition only due to its relatively long overall length and stack height. But, if it fits you and your frame (likely easy for anyone on a size medium or larger), the Revive provides top-of-the-line performance and an additional guarantee of reliability through the easy-to-use Revive Valve.

　　The Revive 2.0 comes in the standard 30.9 and 31.6mm diameters as well as the Revive Max 34.9 and Revive 27.2 (80mm travel only) to cover all possible sizes. It comes in 125, 160, 185, and 213mm drop lengths that should suit most riders needs, and while the stack height is quite reasonable at 42mm (compressed), the overall length is a bit longer than some others due to the 32mm long actuator at the base of the post.

　　Installing the Revive is a fairly standard procedure, although the cut end of the cable is at the post and needs to be inserted into a barrel which is a bit fiddlier than other posts. The seat clamp is a standard 2 bolt and barrel design and the Triggy Alpha remote has two horizontal positioning mounts and the option to adjust the lever angle. While the lever does have a slightly longer throw, it is light action, highly adjustable, relatively ergonomic, and the perforated machined thumbpad even matched the Hope Tech 3 brake levers on the test bike. 

　　The BikeYoke Revive 2.0 has an adjustable return speed, allowing pressures of 210- 290 psi and providing an incredibly smooth, controlled stroke. It is worth mentioning that adjusting the air pressure requires an adaptor supplied by BikeYoke with the post, but you can get around this by removing the Reset Valve. After setting up the post initially, the Revive proved to be the smoothest post in the test group, slightly smoother even than the Fox Transfer. It is actually uncanny just how smooth this post really is. The high-end feel of the Revive post makes small imperfections in the feel of other posts much more noticeable.

　　The most unique feature of the Revive is the Revive Valve, a reset feature that bleeds air out of the system if your post develops sag over time. It takes just a 4mm hex key and mere seconds to reset the post if/when needed. This helps keep your post running smoothly, consistently, and reliably.

　　If the longer insertion length works for you, the Bike Yoke Revive 2.0 is arguably the smoothest, most intuitive, reliable design on the market and should absolutely be considered if you are looking on the higher end of the dropper post price spectrum.

　　Check Price at BackcountryCheck Price at Jenson USA Best High-End Dropper Post RockShox Reverb AXS Specs Available travel lengths 100, 125, 150, 170mm Overall lengths 340, 390, 440, 480mm Available diameters 30.9, 31.6, 34.9mm (Reverb XPLR AXS comes in 27.2mm) Size tested 31.6, 150mm travel Measured weight Post: 655g (4.37g/mm travel), Lever: 54g

　　

　　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 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 34.9mm diameters as well as 27.2mm in the Reverb XPLR AXS thats made for gravel bikes. The larger diameters all come in 100, 125, 150, and 170mm drop lengths which should work for most people. Unfortunately, for the long-legged folks, it does not come in a 200mm length. The overall lengths are pretty reasonable, but it does have a longer stack height of 62mm (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 (150mm 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 5-15mm 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.

　　$645 at AmazonCheck Price at Backcountry Best SL Dropper Post Bike Yoke Divine SL Specs Available travel lengths 80, 100, 125mm Overall lengths 400, 420, 445mm Available diameters 30.9, 31.6 Size tested 31.6, 125mm Measured weight Post: 451g (3.61 g/mm travel), Lever: 45g

　　

　　Pros Fast return speed Smooth, controlled action Quite light Tech climb” feature went unnoticed (in a good way) Cons Max travel of 125mm 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 125mm.

　　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 250psi, it didnt seem to change the action much. Like the Revive 2.0, 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 2.0, and it is similarly smooth in its action. It doesn’t have the Revive 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 2.0 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 125mm, 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 and snappy, and lightweight, making it a great choice for XC riders looking to add an infinitely adjustable, high-performance dropper to their lightweight rigs.

　　Check Price at Jenson USA Best of the Rest Fox Transfer Factory Specs Available travel lengths 100, 125, 150, 175, 200mm Overall lengths 336.6, 391.5, 446.3, 503, 558.7mm (includes actuator) Available diameters 30.9, 31.6 Size tested 31.6, 150mm travel Measured weight Post: 585g (3.9g/mm travel), Lever: 46g

　　

　　Pros Very smooth, intuitive performance on trail Reasonable overall length and very low stack height Super-light actuation Great seat clamp design Basic but well-performing lever Cons Not as easily serviceable and very little adjustability Heavier than some Pricey Paul Clauss The Fox Transfer Factory ($359) impressed us with its smooth travel, light action, and great seat clamp design, as well as maintaining relatively low stack height and overall lengths. It is towards the higher end of the price spectrum, and it doesn’t have a ton of fancy features or adjustment options (or any really). It is also the second heaviest post in the test (only lighter than the RockShox Reverb AXS). But the performance on the trail is simply outstanding. It is important to note that Fox recently announced an updated version of the Transfer, and this review pertains to the previous version, which is still widely available. Well be testing the new version soon.

　　The Fox Transfer comes in 30.9 and 31.6mm diameters and 5 travel lengths, increasing by 25mm between 100 and 200mm. The Performance Elite version uses the same internals but lacks the Kashima coat and retails for $309. While it is hard to quantify if Kashima is actually lower friction, the gold bling certainly helps it stand out. 

　　Setting up the Transfer is straightforward due to the standard design and lack of adjustment options put the barrel on the end of the cable and onto the actuator, feed the cable through the housing, clamp in the lever, and go. Saddle installation is very easy as well, thanks to the pivoting clamp bolts.

　　The Fox Transfer 1x Remote we used is similar to the post no fancy bells or whistles, but a simple, ergonomic design with light action. The metal thumbpad is lightly textured for a bit of grip, and two mounting holes allow you to shift the lever laterally to find the right position. The low profile design is easy to keep out of the way, and the relatively short throw and light lever action make for easy post actuation.

　　On the trail, the Fox Transfer Factory performs reliably and extremely smoothly. It drops quickly when necessary but remains precise when making small adjustments with a consistent return speed. The Transfer does not have an adjustable air spring, but the fixed spring rate seems pretty perfect anyway. While some people may prefer greater adjustability, we found it to work great while having one less thing to need to fiddle with.

　　Weve seen complaints about reliability issues with the Fox Transfer post, but ours has worked perfectly at all temperatures and conditions throughout our test period. In fact, along with the Bike Yoke Revive 2.0, its one of the smoothest posts weve tried. So smooth that it made many of the other posts we tested feel sub-par in comparison.

　　The Fox Transfer Factory isnt the cheapest, lightest, most adjustable, or easily serviceable, but it still managed to seriously impress us with its overall performance. Given the range of sizes, relatively low stack height, and shorter overall lengths, most riders should be able to find a Transfer that works for them.

　　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 Second heaviest cable-actuated post tested 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 31.6mm diameters and 100, 125, 150, 170, and 200mm 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 their gravel or XC bikes, Crankbrothers also makes the Highline XC Gravel in a 27.2mm diameter that comes in 60, 80, 100, and 125mm 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, probably the smoothest action of the low-to-mid price point posts tested. And, being fully user-serviceable with very standard tools, along with including quality components like Trelleborg seals and IGUS LL glide bearings and keys, it should be easy to keep 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, exceptionally smooth, controlled, and reasonably priced post will be very happy with the Crankbrothers Highline 7.

　　Pros Lightest post tested Wide range of shorter travel options for XC riders Drop bar lever available Very fast return speed Extremely light action Cons Two positions — you’ll love it or hate it Less controllable than infinitely adjustable posts due to extremely light action Longest overall length in the test Paul Clauss The Fox Transfer SL Factory ($399) is a lightweight, two-position dropper post intended for XC and gravel riding. 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 31.6mm diameter, it comes in 75 and 100mm drop lengths. In the 31.6mm diameter, it also comes in 125 and 150mm lengths for weight-conscious trail riders. For those riding bikes with 27.2mm seat tube diameters, the Transfer SL 27.2 is available with 50 or 70mm 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 both Factory and Performance Elite 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 485mm for 150mm of drop (17mm 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.

Why You Should Trust Us 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.

　　For the purposes of this buyers guide, we rounded up nine of the best dropper posts available in 2024 to test and compare side-by-side. 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. Each post was weighed and measured for comparison to manufacturers specs and installed on either his Santa Cruz Bronson or Chromag Widangle hardtail for testing. 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 ten 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.

　　

　　Dropper posts allow us to ride harder and more efficiently with our saddles at the appropriate height for the situation; (photo/Heather Benson) FAQ Do I need a dropper post? 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 come down in weight and have become more reliable and durable. Having 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. Being able to adjust 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 many more affordable options that work very well. So, yes, unless you are an elite-level XC racer who is trying to have the lightest bike possible, you should absolutely be riding with a dropper post on your mountain bike.

　　Is it bad to leave my post compressed? Leaving your MTB 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 when you next 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.

　　Can I hang my bike by a dropper post or clamp it to 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 damage it.

　　While clamping to the dropper post stanchion while working on your bike 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 post stanchion. Like with suspension components, scratches on the 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.
