SRAM Rival AXS E1 Rear Derailleur

Wireless shifting without the flagship price tag — the SRAM Rival AXS E1 Rear Derailleur brings cable-free electronic actuation to riders who want consistent, precise gear changes as part of a clean, uncluttered build. It runs on the same AXS Bluetooth platform as SRAM's higher-tier groupsets, so you get full ecosystem integration — including app-based firmware updates and shift customization — without compromise on the fundamentals.

The Rival AXS E1 is designed for 12-speed drivetrains in both 1x and 2x configurations, making it a capable fit for road and gravel setups alike. It works with SRAM's Flattop chain and integrates with the broader AXS ecosystem — blips, satellite controllers, power meters — so your cockpit can be as minimal or as feature-rich as you want. Because shifting is electronically actuated, there's no cable stretch, no housing fatigue, and no degradation in shift quality as the miles accumulate.
