The Finest Dropper Posts of 2024

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, we’ve 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.

Editor’s 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

How We Tested Dropper Posts

It’s 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, you’ll find droppers on virtually all of our mountain bikes and even some of our gravel bikes these days. And we’ve tried a lot of them. Whether for product launches, individual reviews, or on test bikes, we’ve had the chance to try nearly every model on the market.

Our Expert Testers

For the purposes of this buyer’s 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, he’s always seeking out the highest-performance products he can find and appreciates components that make his bike as light as possible.

He’s 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 manufacturer’s 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.

Buying Guide: How to Choose a Dropper Post

There are numerous reasons you should use a dropper post on your mountain bike, but it can be tricky to find exactly what you need. Here, we break down some of the important considerations that may impact your purchase decision.

Why Ride With a Dropper Post?

Using a dropper post will allow you to raise and lower your seat with the touch of a handlebar-mounted lever or remote. When your saddle is at the appropriate height for pedaling and climbing, it can get in the way when trying to move your body and bike while descending. But when your saddle height is set low for descending, it is not in the proper position for pedaling.

Dropper posts allow you to adjust your saddle height on the fly while riding, ensuring you have the proper seat height for the terrain you encounter. With a dropper post, you will experience:

1. Improved maneuverability: A dropper post allows you to lower your seat when descending steep or technical terrain, creating more clearance between you and your saddle This makes it easier to shift your body and maneuver the bike. It is particularly helpful for bike/body separation when cornering and when jumping. 
2. Better efficiency: At full extension, your saddle should be in the ideal position for seated pedaling so you can always make the most of your pedaling effort.
3. More comfortable riding: A dropper post allows you to adjust your seat height based on the terrain, making for a more comfortable ride overall. Outside of lowering the post for descending, this can be important on technical climbs — sometimes, having only 20mm or so of saddle drop can help you put down the power or maneuver the bike through challenging sections. 

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 manufacturer’s 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.

Dropper Travel Length

Dropper posts come in a range of travel lengths to suit varying needs, preferences, bodies, and bikes. For mountain bikes, they typically range between 100 and 200 mm, with some outliers on either end. For example, the OneUp Components V3 Dropper comes in the most size options, with 90, 120, 150, 180, 210, and 240 mm travel lengths available. Not surprisingly, as post-travel increases, so does the overall length of the post.

While many people try to fit the most drop possible on their bike to increase mobility, some riders may prefer a shorter drop length for various reasons. How much drop you want is usually a matter of personal preference, but also it may be a function of what will fit on your frame and work for your body size.

Fortunately, some brands are doing their best to minimize the overall lengths and stack heights of their posts, which makes it easier to fit a longer travel dropper. Some brands/models also provide the option to reduce travel with adjustments to make fitment much easier than it used to be. At the same time, many modern bikes are being designed with lower stand-over heights and shorter, straighter seat tubes that help make it easier to fit longer travel dropper posts.

Determining If a Dropper Will Fit Your Frame

Most manufacturer’s websites have a tool to help you appropriately size a post for your bike to maximize travel (and the OneUp website will even show you which competitors’ posts will fit with their Dropper Post Length Selector). To use these tools, you’ll take two measurements from your frame and consider a few post measurements:

• X – your Measured Ride Height: from the top of your seat collar to the center of your seat rails (not the top of your saddle). For example, on the small Santa Cruz Bronson used for testing, this is 260 mm.
• Y – the maximum seat tube insertion length for your frame. On the small Bronson, this is 210 mm.

With these numbers, use the tools available on most manufacturers’ websites to determine the maximum travel for their post on your frame. To double-check if a dropper post will fit on your own, make sure that:

1. Your Measured Ride Height (X) is GREATER than the Stack Height (extended) of the post, measured from the bottom of the collar to the center of the seat rails of the seat at full extension.
   1. On the test Bronson, the Measured Seat Height of 260 mm is greater than the 150 mm Travel PNW Loam post’s Stack Height of 200 mm. This means the post can be positioned at the preferred height, assuming the other two measurements below are true.
2. The Overall Length minus your Measured Ride Height (X) is LESS than the maximum seat tube insertion length for your frame (Y).
   1. For the PNW Loam post at 150 mm travel, the Overall Length is 440 mm. 440 – 260 = 180 mm, which is the length of the post I expect to be in the seat tube at full seat height. This is less than the measured seat tube insertion of 210 mm, leaving 30 mm of clearance at the bottom of my seat tube with the post at the measured seat height.
3. The Insertion Length (from #2) falls between the minimum and maximum insertion lengths of the post. The insertion length must be between the maximum/minimum insertion lengths for the post.
   1. The minimum insertion of 90 mm is less than 180 mm (from #2, the expected insertion length with the post), which is less than 210 mm (the maximum insertion depth). At the expected insertion on the Bronson frame, the insertion length falls between and maximum and minimum insertion lengths of the post.

Types of Dropper Posts

Most dropper posts available today use a cable to actuate an internal floating piston (IFP) to release a pressurized chamber, typically an adjustable air spring or a sealed hydraulic cartridge, to raise and lower the seat. While they all perform the same task of raising and lowering your seat on the fly, dropper posts come in a variety of different designs.

Adjustable vs. Fixed Rate of Return

Many dropper posts have an adjustable rate of return. Typically, this involves an air spring, the pressure of which can be raised or lowered (within a recommended range) to speed up or slow down the rate at which the post compresses and extends. This gives the user greater control over the post and the ability to dial in its performance to meet their needs or preferences. The Bike Yoke Revive 3.0, Fox Transfer Factory, Wolf Tooth Resolve rev2, Bike Yoke Divine SL, and the PNW Loam all feature adjustable air springs.

Some posts use sealed cartridges that have a fixed rate of compression and extension. These posts have a predetermined spring rate chosen by the manufacturer that usually aims to hit the happy middle ground of compression force/return speed. The OneUp Components V3 and Crankbrothers Highline 7 are two examples of droppers that do not have adjustable air springs.

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.

Actuation Styles

Cable-Actuated

The majority of modern dropper posts are cable-actuated, meaning that a cable connects between the remote lever and the actuator at the bottom of the post. When you press the remote lever, it pulls on the cable, which in turn actuates the post and allows it to move up or down. Cables are relatively easy to deal with and inexpensive to replace.

Hydraulically Actuated

This style of actuation is much less common than cable-actuated posts, but it works in a similar way using hydraulic fluid. The RockShox Reverb (not AXS) is the only post on the market that uses this system, and it works fairly well. The main drawback is that it is more difficult to install and remove your post, given the presence of hydraulic fluid in the hose and remote lever, and it can be quite messy. Older models were also quite sensitive to cold temperatures, although the latest Reverb posts work better in that regard.

Wireless/Electric

Given the rapid pace of technological development, it comes as little surprise that more and more products are electronic. Wireless or electronic posts forego the cable or hose altogether and instead use a small control unit on the handlebar that pairs via Bluetooth to a small motor on the post to raise and lower it. The RockShox Reverb AXS was the first electric post to really gain a foothold in the market. More brands are making wireless components, and Fox recently launched the Transfer Neo (which we will be testing soon).

Dropper Features

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.

Reset Valves

All hydraulic dropper posts can experience air ingestion into the inner tubes over time, which can result in a saggy or spongy feel when sitting on the saddle. To combat this without requiring a full rebuild of the post, the Bike Yoke Revive 3.0 uses a reset valve, and the RockShox Reverb AXS uses the “Vent Valve” to reset the hydraulic circuit. While Bike Yoke only expects Revive users to use the reset valve once or twice a year, this is a nice feature to ensure consistent performance of the post without needing to pull it out of your frame.

Other posts, like the Wolf Tooth Resolve rev2 and the Bike Yoke Divine SL, have “self-bleeding” cartridges designed to purge any air from the system every time the post is fully dropped.

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 don’t typically install/remove our saddles frequently, these seemingly trivial design features are really quite helpful when testing dropper posts back to back. 

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.

Some brands still make remote levers designed to be used with 2x drivetrains and/or suspension lockout levers, and drop-bar levers are becoming more common as droppers gain popularity on gravel bikes.

Like any other handlebar-mounted control, it is important to consider ergonomics, lever feel, and actuation force when selecting a dropper post lever. Additionally, you’ll want to consider how your lever will mount to your handlebar. While most lever manufacturers do provide options for Shimano i-Spec or SRAM MMX shifter/brake mount connections, they also offer basic 22.2 and 31.8mm handlebar clamps. Often you can find adaptors for other brake configurations like Magura, Hayes, Hope, etc.

Because most levers have multiple attachment points to adjust the horizontal position of the lever, it is usually fairly easy to position the remote in a good spot so that reaching it with your thumb feels natural and intuitive. Some levers have additional adjustments that allow ergonomics to be customized even further.

The exception to the cable-actuation rule is the RockShox Reverb AXS, which comes with its own electronic control unit. This remote runs off battery power and connects to the post via Bluetooth.

Weight

Dropper posts will always weigh more than a standard seatpost, but most riders (and increasingly, even competitive cross-country racers) are willing to take a weight penalty for the enhanced handling and control benefits of using a dropper post. Of course, all other things being equal, lighter is generally considered better, assuming performance isn’t compromised in the name of weight savings.

For this test, we weighed the post only, knowing that the weight of the cable housing will vary slightly depending on the length required for your frame, and that will also generally be consistent for your bike regardless of which cable-actuated post you choose. It is also worth noting that longer travel posts weigh more than shorter travel versions of the same post due to the additional materials needed to make them longer. And, since our testers used different lengths of posts, it is challenging to get a perfect weight comparison.

While a heavier dropper post won’t be as noticeable on the trail as a heavy set of tires or wheelset, it will add to the overall weight of your bike and may be a consideration for you. All the posts in this test weighed between 441 grams (Fox Transfer SL) and 655 grams (Rockshox Reverb AXS). For the cable-actuated droppers, the OneUp V3 is consistently one of the lightest weight options, weighing in at 515 grams in the 210 mm travel length (433 grams for the 150 mm version).

The Wolf Tooth Resolve is close behind at just 514 grams at 160mm of travel (with 10mm more travel). For those super conscious about weight, like XC racers, there are some “superlight” options on the market nowadays, like the Fox Transfer SL and the Bike Yoke Divine SL. These lightweight models do save a fair amount of weight, coming in at 441 grams and 451 grams, respectively, but they are offered in a narrower range of drop lengths. Not to be outdone, the OneUp V3 droppers are now lighter than the SL models we tested (in the same drop lengths).

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 doesn’t 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.

1. 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.
2. 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
3. Push the post into the frame while simultaneously pulling the cable/housing (or hydraulic line) out of the exit port near the head tube.
4. Attach the cable/housing to the lever after mounting it to the handlebars.
5. 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 for Gravel Bikes

As the gravel bike market continues to grow and mature, some models are coming equipped with dropper posts, and/or the frames feature internal cable routing to accommodate one. Of course, not everyone needs or wants a dropper on their gravel bike, but those who ride steeper, rougher roads or like to venture onto singletrack trails may find that the benefits outweigh the slight weight penalty.

Most, but not all, gravel bikes have smaller 27.2 mm seat tube diameters, and fortunately, many brands now make droppers in this size to meet the growing demand. In general, dropper posts made for gravel bikes have less travel, ranging from around 50 mm to 125 mm. On the more affordable end of the spectrum, OneUp Components makes the V3 27.2 in 90 and 120 mm drop lengths.

Crankbrothers offers one of the largest ranges of drop lengths with 60, 80, 100, and 125 mm options for their Highline XC Gravel post. Fox makes a 27.2 mm version of its lightweight Tranfer SL in both Factory and Performance Elite in both 50 mm and 70 mm drop lengths. At the high end of the price spectrum, the RockShox Reverb XPLR AXS brings wireless dropper technology to your gravel rig.

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 what’s 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. It’s not that less expensive droppers don’t 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 don’t already have one). This post doesn’t reinvent the wheel, but it performs very well and is an exceptional value for anyone who doesn’t have more to spend.

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 that’s a pretty big spread, but that’s 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 V3’s 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.

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 brand’s first wireless component — and a sure sign they are developing many more — and it functions similarly to the Reverb AXS. We haven’t tested Fox’s 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 you’re 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).
