Why We Like The Reverb AXS Dropper Seatpost

Whether you're a neat freak looking for a way to tidy up your cockpit, or you're a hunter of the newest, sleekest components, we wouldn't fault you for giving RockShox new Reverb AXS Dropper Seatpost a good once-over. This elite new dropper skips the cables, opting for electronic actuation that wirelessly communicates between a sleek button at your cockpit and your dropper post for a setup free of hoses, routing, and wasted energy. All of this has been enabled by SRAM's AXS technology that brings a new level of interaction, personalization, and connectivity to your steed.

The post itself is smoother to move than previous generations, requires less downward pressure to drop, and can be stopped in any number of positions between its base and highest reach. It uses a new lower-friction IFP that allows for faster actuation of the post, preventing sluggish rebound when you need your saddle at full-mast for punchy pedal fests at the bottom of a descent. The post also features new Vent Valve technology that enables super simple servicing. While RockShox builds the post to be resilient to rigorous use, there's no debating that sometimes things just don't go as planned, and being able to perform quick-fixes is a must — especially on a dropper post that rings in on the high-side of triple-digits. Vent Valve technology is a fail-safe put in place that we hope you never have to use, but enables you to service the post in the event that oil and air mix, without disassembling the post all together — all that's required is that you depress the valve, compress the post, and you're good to go. Air will channel back into the air chamber, leaving the oil where it belongs.

  • Effortless wireless dropper post with infinite adjustment
  • Clean, simple installation with no cables to worry about
  • Updated internals give speedy return no matter the conditions
  • Simple, reliable service solution with new Vent Valve technology
  • SRAM AXS technology actuates dropper with the tap of a button
  • Battery offers 40hrs of trail life, recharges in under an hour
  • Controller, battery, and charger included for out of the box use
  • Battery is compatible with both SRAM AXS derailleur and RockShox Reverb AXS dropper

I decided to upgrade the dropper post on my XC bike to the Reverb AXS. Admittedly, I thought this upgrade was more about embracing technology and getting rid of the dropper cable. That said, I’ve found that I use the dropper more frequently because it takes less effort to engage (both at the remote and at the saddle). It’s so easy that I’ll even drop the saddle for short stretches. Due to the battery placement, you may have to think through seat bag placement. I got the Lezyne SendIt Caddy and that works fine to hold the spare tube, CO2, and levers without putting any unnecessary pressure on the battery. I’d definitely recommend the Reverb AXS.

I recently got a Specialized Epic with AXS drivetrain and needed to add a dropper. I love the cable free cockpit so wanted a wireless dropper to match. Install and set-up were dead simple since no cable routing was involved. The seat clamp design is better than most and seat position and angle were easy to set. The remote and dropper paired instantly with no fuss. There is a tool included for self-service if you ever need to bleed the internal piston. Battery, charger, and cord were included. The remote and dropper combined added exactly one pound compared to the carbon fiber post that it replaced. Function seems really good. Force required to drop it is on par with anything I've used and the return function is perfect. Cons: The remote sits low enough that in a crash it will hit the top tube. The shifter remote is the same on the AXS drivetrain so now the potential for issues is doubled. $800 is a crazy amount for a dropper. Bonus: If derailleur battery dies you can swap with the dropper battery. Maybe I just paid $800 for a spare battery carrier 😂💵


Is the dropper distance configurable in the app? Like can I tell the post to always raise up to 90% instead of 100% when the button is pressed?

Does the Sram axs dropper post comes with the remote control?

Best Dropper with a Price tag to match

I've put it through the wringer

I picked up a reverb AXS to go with my AXS drivetrain, partially to see what all the buzz was about and partially to have a spare battery to swap over to the rear derailleur just in case I forget to charge it and it dies mid-ride. My experience with earlier gen Reverbs were pretty much like everyone else... It worked great for a while and then never really worked ever again after a few months. I'm at about 6 months on my Reverb AXS and can say that I believe it is the best dropper post on the market in terms of operation, and have had zero reliability issues so far. Just as something like a PNW or Wolftooth lever is a big upgrade to a cable post, the wireless actuation of the Reverb AXS makes it utterly effortless. I find myself using my dropper a lot more than I ever did before thanks to how easy it is to actuate. If you get to try one of these, you'll start to notice how much time you spend depressing the lever of your cabled post and waiting for it to trigger and actuate. The main downside, which I'm sure you've already seen, is that this post is expensive. Twice the price of Fox Transfer, expensive. That being said, if Rockshox really does have their reliability figured out (and it seems like it), this is a premium investment that will set you back but be worth it in the trail experience.

Awesome dropper!

I've used it several times

Bought this along with all the parts to build up a new Ibis Ripley. I already had the Eagle AXS derailleur and shifter on my last bike and it’s a nice step up from the regular Eagle stuff. The dropper is much better than the previous dropper I had which was a Fox Transfer. So precise , quick and consistent. Expensive and not the lightest but by far the best dropper I’ve ever used.
