Seatposts

Our intention with Reverb AXS was inventive and pure: No hoses. No routing. No energy wasted. Not a single thing in the way of the experience. We created a reliable wireless-electronic dropper post and controller that actuates with drastically less effort and zero distraction.

No hoses to route, no fishing required. - Updated internals for faster return speed in all conditions. - New Vent Valve Technology, a simple and reliable built in service solution without disassembly of the seatpost. - SRAM AXS technology, a new level of interaction, personalization, and connectivity across all AXS-enabled components. - Includes RockShox AXS handlebar controller, rechargeable SRAM battery, and charger.

The carbon Service Course SL seatpost is specifically tuned to be more shock absorbing than the "comfort" seatposts on the market, while still passing our strict internal MTB strength test. Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain. Better fit means better performance, and if your saddle is out of position, you'll waste energy with every pedal stroke. The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt-head accessibility. The Service Course SL seatpost makes it possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types. - Distinctive Zipp cosmetics - Unidirectional Carbon fiber tuned for ride comfort - Lightweight clamping system - Lifetime warranty
