SRAM X01 Eagle AXS rear derailleur

The SRAM X01 Eagle AXS rear derailleur is a 12-speed electronic rear derailleur for mountain bikes, operated by a motor rather than a cable. Designed for enduro and trail riding, it has a shorter forged aluminium cage and stainless steel hardware, providing 10 mm more ground clearance.

The Overload Clutch disengages on impact and immediately returns to position, protecting the rear derailleur. The system is tested to IP69K against water and dust, while the battery is purchased separately. It can be programmed and customised through the AXS app. It is available in black-grey and black-red.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
