Dropper posts are one of the single most important inventions for the modern mountain bike. Disc brakes ultimately come out on top, but the advent of mountain bike dropper posts has completely changed how mountain bikers ride and handle their bikes.

A dropper post is a simple device when looking at it from the outside. The inner workings reveal a much more complicated picture.

There is a litany of dropper post styles, lengths, and travel to choose from. Your choice depends on the kind of terrain you want to traverse.

Finding the right dropper post can be a simple or complicated process. In this article, we’re going to make it easier to pick the perfect one to fit all your needs.

From the simplest and most affordable dropper posts to the top-of-the-line posts used by Olympians and World Champions, we’re going to cover the best dropper posts for riders of all levels of ability.


A Short Introduction to Dropper Posts

Dropper post trigger
Trigger mounts to the handlebar, making it easy to use.

Dropper posts are adjustable seatposts that can be raised or lowered at the push of a button or lever, called the trigger. The trigger is typically mounted on the handlebars, next to the brake and shift levers.

A cable connects the trigger to the dropper post and can be routed internally or externally. When the rider pulls the trigger, the dropper post will naturally raise, or return the saddle to its maximum height position. Most riders set up the maximum height as their ideal saddle height which is best for efficient and powerful pedaling.

In order to lower the dropper post, all the rider needs to do is pull the trigger and put their body weight down on the saddle.

Dropper posts work in the same way as an office chair, in this sense. Pulling the lever returns the chair to its maximum height while pulling the trigger while putting your body weight on the chair causes it to lower.

That’s all there is to it. Dropper posts have different sizes, lengths, and travel which is the distance the seatpost can lower into the frame.

Mountain bikers use dropper posts for steep and technical descents or sections of trail. Lowering the saddle gives you more space to move in and out of the saddle. You can shift your bodyweight more easily and readily with the seatpost pushed into the frame. Then use the trigger to pop the saddle back up to its normal height as the trail levels out.

Here are some of the best dropper posts that you can buy, from the simple and affordable, to the very best.

PNW Components Loam

PNW Components Loam Dropper Post

  • Customizable speed return
  • Diameters: 30.9mm, 31.6mm, 34.9mm
  • Max length up to 540mm with 200mm travel


The PNW Components Loam is one of the best value dropper posts on the market. Made with 7075 Aluminium Alloy, the dropper post is simple and reliable. PNW offers three different seat tube sizes and four travel lengths to have a model that will fit everyone.

The Loam comes with a lifetime warranty and on-bike travel adjustment up to 25mm. Customizable speed return is another unique feature of the Loam, which weighs in at 524g.

Not included with the Loam is its own lever, which is a bit expensive for a value dropper post at $69. However, the entire unit is easy and reliable, which means you’re likely never going to have to replace it.

The 55mm stack height can be a bit high for some. Thankfully it’s not enough to get in the way of a smooth and comfortable ride.

One concern is the significant side play in the saddle which makes the Loam seem less sturdy. However, this play doesn’t affect the unit’s performance and is at all a sign of a poor build.

RockShox Reverb AXS

RockShox Dropper Post

  • Industry’s first wireless-electronic dropper seatpost
  • Updated internals for faster return speed
  • Vent valve technology makes for easier servicing


The RockShox Reverb AXS is truly top of the line. Complete with an electronic trigger button, the unit is incredibly easy to set up and service.

Plus the updated internals make post actuation faster than ever. Even less downward force is required to drop the saddle as well. That makes the Reverb AXS one of the smoothest-running posts on the market.

It will cost you, but the Reverb AXS is top quality. Available in three different diameters (30.9mm, 31.6mm, 34.9mm), the Reverb AXS has a maximum length of 440mm, and weighs 650g.

The weight is surprising given the cost of the unit, but keep in mind that many manufacturers don’t include the trigger or cable in their product’s weight.

You can even use the Reverb AXS on multiple bikes – not at the same time, obviously – since there are no strings/cables attached.

Even in wet and muddy weather, the electronic system isn’t fazed. The electronic trigger is easier to operate than mechanical levers, which makes it even better for rough and technical terrain.

A dropper post is a height-adjustable seatpost that can be raised or lowered at the push of a button (called the trigger).

Dropper posts are used to lower the saddle or seatpost out of the way during steep descents or technical trails in mountain biking. This kind of riding requires significant shifts in bodyweight fore and aft, and side to side, which can be hampered when there is a saddle in the way.

Dropper posts allow complete freedom of movement for mountain bikers. You don’t have to worry about bumping into or getting caught on the saddle.

A dropper post should be positioned so that at its highest point (full extension), the saddle is at your normal seat height (position for optimal seated pedaling). You never want your dropped post to be higher than your normal seated position, as it should do down into the frame instead.

Technically, yes. But practically, no.

In order to fit a dropper post onto your bike, you need a certain amount of insertion depth and length in the frame to accommodate for the dropper post travel. You will also need a certain seat tube diameter and room for the internal or external cable routing for the trigger.

So yes, you could technically put a dropper post on any bike from a mountain bike or gravel bike, to a road bike or a hybrid. But the performance benefits do not outweigh the cost, hassle, and potential ‘misfitting’ of putting a dropper post on an old road bike, for example.

There are a number of different ways to measure your seat height, from laser beams to anatomical estimates. Here are a few, summarized:

  • Heel method: at in the saddle, push your crank arm all the way down with your heel. At the bottom of the pedal stroke, your leg should be completely straightened, with your heel still touching the pedal.
  • 109% Rule: measure your inseam and multiply this number by 1.09 (or 109% of your inseam). The answer is your seat height.
  • Holmes Method: film yourself riding on a turbo trainer with your feet in their normal position on the pedals. While analyzing the video, pause at the moment that your foot is at the bottom of the pedal stroke. Here, look for your knee angle, which should be 25-35 degrees.

Besides using the above methods, you will notice a few things if your seat is too high. Your hips may be rocking back and forth as you pedal, because your leg is extending too far and reaching for the pedals.

Your toes may also become pointed at the bottom of your pedalstroke. You can even experience back pain or sit bone pain from having too much or uneven pressure from your bodyweight on the saddle. In general, being uncomfortable on the bike is a sign that your seat height is incorrect.

Yes, you can adjust a mechanical/cable-actuated dropper post by checking and adjusting the cable tension, including using a barrel adjuster. Always check the manufacturer’s manual and warranty before making any major adjustments including removing the dropper post from the frame or replacing the cable.

Dropper posts are controlled by a trigger mounted to the handlebars and next to the brake and shift levers. With a pull of the trigger, the dropper post will pop up and be raised to its maximum height. In order to lower it, all you need to do is pull the trigger while seated (pushing your bodyweight down in the saddle) and the seatpost will descend.

Internally, dropper posts are controlled by either pressurized fluid systems (hydraulic dropper posts) or locks and pins (mechanical) which are controlled and activated by the trigger.

Dropper posts became popular in mountain biking in the early 2000s. Modern technology allowed for huge advancements in the device which was first created in 1984. The Hite-Rite was the first adjustable seatpost for mountain bikes and featured a clunky, spring-like design that certainly worked, but didn’t work well.

The design of the modern dropper post was created by Wayne Sicz in 2002. The Gravity Dropper Classic and Descender were the first modern dropper post models that became wildly popular in the mountain biking community, and have paved the way for the dropper post revolution.

Installing an entry-level dropper post will cost at least $100, and more often $200-300. Lower-end models will be heavier and more basic in function, which the more expensive models (>$300) will be significantly lighter and race-ready.

You can use a spacer, insert, dropper post remote, or even a plastic shim to limit dropper post travel. This is ideal for variable terrain riding when you want to drop or raise your post part-way and still be able to pedal comfortably.

For minor adjustments, many dropper posts come with their own adjustable systems, which you can use to adjust your ride height in 5mm increments in some instances.
