Ridden and Reviewed: Rockshox Reverb AXS Wireless Dropper Post

Written by Contender Bicycles, on March 03, 2021

It's hard to argue against the value of a dropper seatpost. It’s fair to say the dropper post is the best thing in mountain biking since clipless pedals, tubeless tires, and suspension. Few seatposts are as ubiquitous as the Rockshox Reverb, both in function and notoriety. New this year is the Rockshox Reverb AXS, which improves on the Reverb in every way. Rockshox Reverb Wireless Dropper Seatpost Details, Details, Details Let’s get this out of the way: yes, its wireless, and yes, they’ve improved the internals of the previous Reverb. The wireless remote falls into the SRAM AXS family, and can be configured to work as a dropper lever, or be paired to work with a 2x SRAM AXS drivetrain. Additionally, it can be paired to your SRAM AXS shift lever, meaning one lever can control both shifting and your dropper. RockShox Reverb AXS Wireless Dropper Seatpost - Contender Bicycles All of this is configurable through the AXS App, which syncs with other AXS components to review battery life, track usage, and receive firmware updates.. Or not. SRAM says users don’t need the app to get the most out of any AXS product; just install, pair, and ride off. Current Reverb seatposts are notorious for developing sag or squish in the travel. This is usually accompanied by play in the seatpost, slow return speeds, and a realization that air has somehow gotten into the hydraulic system. Generally, this required a bleed of the entire system, and if enough of these happened, a complete rebuild. Reverb AXS takes care of all of that and then some, through what they call their Vent Valve. Pull out the seatpost, press the valve found on the bottom of the post, compress (or drop) the seatpost, and go. The air is channeled back into the air chamber, and the seatpost returns to top form. Rockshox Reverb AXS Dropper Seatpost Air Vent Release This is combined with an updated internal floating piston (IFP) which is geared toward lower friction, less required service intervals 600 hours in between bleeds compared to 200 hours for current Reverb droppers. You’ll also find an updated post head with a single rail-retention bolt makes for a quick and effortless saddle install. One of the benefits of SRAM wireless is ease of setup, and that extends to the Reverb AXS dropper as well. Less hydraulic fluid lines means fewer places for air to seep into the system and fewer ways of the seatpost developing play, and when that does happen there’s the easily-accessible Vent Valve. Further, adjusting seatpost height is a quick and tactile button click away, providing greater control and ease of use over any other dropper remote on the market. RockShox Reverb AXS Wireless Dropper Seatpost Diameter - Contender Bicycles Reverb AXS is available in 30.9mm, 31.6mm, and 34.9mm diameters, in 100mm, 125mm, 150mm, and 170mm travel lengths. Battery must be charged every 40-60 ride hours, with battery going from dead to fully charged in under an hour. Conclusion How does all this tech work on the trail? In short, very well. You certainly don’t want to think about how well your dropper post works while you’re using it, it just needs to work. And in our time with it, Rockshox Reverb AXS Dropper Seatpost never missed a beat. It moves with a buttery purposefulness that befits a hydraulic system, and the wireless remote makes for easier adjustments than the standard 1x remote. RockShox Reverb AXS Wireless Dropper Post - Contender Bicycles When a dropper seatpost works well, there isn’t too much to say. The Rockshox Reverb AXS fits in very neatly the new SRAM Eagle AXS drivetrain, and combines all of the best features of the Reverb with none of the caveats. We didn’t think about it too much before, during, and after our time with it, which is the biggest compliment one can give to a dropper seatpost. Easy to use, high performance, and reliable - what more can we say? RockShox Reverb AXS Dropper Seatpost with Remote Have any questions about the Rockshox Reverb AXS Dropper Seatpost?

  • Thanks for reaching out and checking out our review of the Rockshox Reverb AXS. Rockshox recently built out a version of their dropper called the Reverb XPLR AXS. That one comes in a 27.2mm diameter and is wireless too, though the dropper lengths are designed more for a gravel bike than a full-out mountain bike.

    We hope to have them finally start to come in early April. Let us know if you have any other questions.

  • Do you make an Wireless Dropper Seatpost for 27.2

    Brian on

  • Need a version with LOTS of layback to counteract the ever-increasing seat angles on bikes.
