SRAM Rival AXS E1 Rear Derailleur

The SRAM Rival AXS E1 rear derailleur is a choice for road bikes with a 12-speed drivetrain and precise wireless shifting. It is compatible with cassettes from 10-28T to 10-36T and works with both 1x and 2x drivetrains, making it suitable for different crankset configurations.

Chain management keeps the drivetrain quiet and secure, and the AXS system makes it easy to customise the settings. The jockey wheel bearings are steel. The rear derailleur is available only in black, so there is no colour choice to make. The AXS battery is not included and must be purchased separately if you do not have one.

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.
