The RockShox Reverb AXS: The First Great Gravel Dropper Post?

SRAM Launches eTap AXS for Road and Gravel

SRAM launches an all new drivetrain, the eTap AXS that looks to bring real benefits of wireless electronic shifting to road and gravel bikes. Wireless has some incredible potential in bringing unprecedented personalization and control, while minimizing complexity. While specifically designed for MTB applications, the RockShox Reverb AXS could certainly bring advantages for the gravel cyclist as well. Hopefully they will also offer a 27.2 version in the near future, as this could be a nice solution for old and new gravel bikes available today.

A Wireless Electronic Reverb Dropper Seat Post

No hoses. No routing. RockShox created a wireless-electronic dropper post and controller that actuates with drastically less effort and zero distraction. The battery on the AXS kit is easily removable, clicking in and out of its holder. SRAM says that battery life is about 20 hours of riding and it can be swapped between Eagle AXS, Reverb AXS and RED eTap AXS systems. Checking the battery life is easy, with a simple press of the derailleur button. Green means you are good to go, with red signifying less than half a charge. Finally, the battery is completely dust and waterproof.

We also know, sometimes the inevitable happens. Over time, air and oil may mix, resulting in that annoying post “squish” and the need for additional service. Vent Valve Technology allows you to do this simple service within a few steps, without any disassembly of the post. Depress the valve, compress the post, good to go. The air is channeled back into the air chamber leaving the oil where it belongs and you back to more confident reliable performance.
