SRAM Red eTap AXS E1 Rear Derailleur
The core of the AXS ecosystem, the new SRAM Red eTap AXS E1 Rear Derailleur is lighter, more efficient, and more capable than ever before. Covering cassette ranges from 10-28T up to 10-36T, this wireless marvel features larger pulleys to reduce chain articulation and increase efficiency, along with an Orbit fluid damper to maintain stability over rough terrain. One derailleur is ready for 1x or 2x, on-road or off-road.

About SRAM
Reinventing the ride, one component at a time.
Founded in Chicago in 1987 with a single product — Grip Shift — SRAM has spent four decades reinventing how riders interact with their bikes. From the first wireless electronic groupset to today's AXS ecosystem, the brand keeps asking the same question: how do we make the next ride better?
Wireless. Configurable. Ride-aware. SRAM's AXS platform replaces a tangle of cables and proprietary protocols with a single, app-driven ecosystem that spans road, gravel and mountain. Components talk to each other and to you.
