RockShox Reverb AXS B1 Dropper Seatpost
The RockShox Reverb AXS B1 Dropper Seatpost brings more seatpost lengths and updated durability to your mountain bike. This AXS dropper seatpost now uses an air-over-air internal design. This makes it more robust and durable than the previous version. In addition, with travel options from 100 mm to 250 mm in 25 mm steps, there is now a size for every rider. It also introduces ActiveRide, a unique feature that provides a small amount of travel. This is ideal for technical climbs, especially on E-MTBs, where added traction and comfort can make a real difference.
The Reverb AXS B1 also now supports all saddle rail types, including 7x7mm round, 7x9mm oval and 7x10mm carbon rails. The battery has been relocated from the top of the seatpost to the collar which improves tire clearance and reduces the risk of interference with accessories like saddle bags. In addition, the rechargeable AXS battery offers 60 hours of battery life. With wireless AXS actuation and simple and tool-free setup, the Reverb AXS B1 delivers a clean look and smooth performance in any conditions.
