SRAM Reverb AXS Wireless Dropper Seatpost – Full AXS Ecosystem Integration

The SRAM Reverb AXS dropper seatpost is designed for modern mountain and e-MTB riders who value a clean bike setup, reliability, and fully wireless integration. It completes the AXS ecosystem, allowing you to use the same battery, controller, and charger as other SRAM AXS components. Thanks to its wide range of travel options, this seatpost is easy to adapt to different frames and riding styles – from trail to enduro and e-MTB.

Key features:

• Fully wireless AXS system: simple installation without cables, a clean bike appearance, and reliable performance in all conditions.
• Shared AXS battery: compatible with SRAM GX, X0, and XX AXS components – one battery for the entire system.
• Wide drop range: available travel options from 100 mm to 250 mm, suitable for a wide variety of frames and rider heights.
• Increased battery clearance: more space around the battery, especially beneficial for modern frames with complex geometry.
• New air-over-air design: updated internal construction delivers improved durability and long-term reliability.
• ActiveRide function: provides a small amount of compliance for technical e-MTB riding when the seatpost is not fully extended.
• Compatible with all saddle rail types: supports 7×7 mm, 7×9 mm, and 7×10 mm rails.
• Individual fit options: the SRAM Reverb AXS length calculator makes it easy to choose the correct travel based on your bike and riding style.
