Innovation is a constant within mountain biking, with manufacturers always striving to make incremental improvements wherever possible. Occasionally, a breakthrough occurs in the development cycle that ushers in a new era of technology, redefining industry standards. The introduction of the dropper post was one such breakthrough, as it forever changed how riders adjust saddle height.
With the introduction of the cable and hydraulic-actuated dropper post, the days of stopping to adjust a seat post by hand were over. Dropper posts allowed a new style of riding entirely, with riders actuating their post many times a ride to achieve the ideal seat height for any scenario, all in a split second. In an bid to further improve dropper technology, RockShox launched the Reverb AXS in 2019, creating the first wireless dropper post, and still the best.

Instead of relying on cables and cumbersome routing, the AXS Dropper utilizes a wireless remote to initiate saddle height adjustments. By eliminating another cable on the bike, RockShox has effectively reduced clutter on the handlebars while introducing one of the most responsive dropper posts on the market.
Installing cable-actuated dropper posts can be tedious, requiring navigating cable routing, cutting, routing housing, and fine-tuning tension adjustments. The Reverb AXS streamlines the installation process in a big way with its wireless design.
Installation simply involves mounting the AXS controller, setting the post at a desired height, and charging the battery. Once mounted on the bike, the post and controller pair together quickly; all you have to do is simultaneously press the sole button on each. Assuming the batteries are charged, an AXS Reverb install can be done in under 10 minutes.
One of the standout characteristics of the AXS Reverb is its instantaneous actuation. Unlike traditional cable-actuated dropper posts that have drag in the system from the cable running through the housing, the AXS system only requires a light touch. This exceptionally light action makes initiating dropper adjustments on the fly even easier. Cable-actuated dropper levers have a longer throw and can lose tension over time due to cable stretch. The battery-powered AXS controller remains crisp and responsive for the battery’s 2 year lifespan.
Out on the trail, the Reverb AXS is one of the most responsive dropper posts on the market and has an exceptionally smooth action in all weather conditions. Like all other components in the AXS lineup, the Reverb AXS system is waterproof. As long as the battery is properly installed, its smooth surface ensures a tight seal, keeping debris and contaminants out. The Reverb AXS will easily withstand a mud-soaked Bellingham winter, an impressive feat.
SRAM AXS Integration
The battery on the Reverb AXS tucks away nicely on the back of the post head, just beneath the saddle. The battery securely latches into place but can be easily swapped and is cross-compatible with other SRAM AXS components. Universal support is available via the SRAM AXS Mobile app.
SRAM AXS Batteries
SRAM's AXS batteries are compatible with all other AXS components, allowing riders to swap them between dropper posts, derailleurs, and even Flight Attendant suspension products as needed.
How Long Does a Reverb AXS Battery Last?
The RockShox Reverb AXS is designed to last for up to 60 hrs ride time with a fully charged battery.
Eagle AXS derailleurs have an expect life time of 25 hours, while AXS equipped suspension lasts 20 - 35 hours of ride time.
How long does it take to charge an AXS battery?
A SRAM AXS battery can be fully recharged in an hour. An amber light indicates that the battery is properly charging, and a green light indicates that the battery is fully charged.
If the charger displays a red light, an error has occurred. Reinstall the batter and disconnect/reconnect the charger to resolve this issue.
Tool-Free Maintenance // How to Use Reverb AXS Vent Valve Technology
The RockShox AXS Dropper post includes its Vent Valve Technology for tool-free service. Over time, dropper posts can develop a bit of “squish.” This squish occurs when air gets mixed with the oil inside the system. Vent Valve technology is a tool-less fix, moving the air back to the chamber and decontaminating the oil. Depress the valve, compress the post, and the post will return to its ideal function.
The Reverb AXS has eliminated the need for intricate cable routing, opting instead for a wireless remote system. While the introduction of a wireless system doesn't revolutionize dropper posts as we know them, it have an array of benefits not seen with cable actuated post. Most notably, the Reverb AXS offers an exceptionally light lever action and an industry leading responsiveness regardless of weather, making it a standout choice in the dropper post market.
