SRAM RED eTap AXS (RD-RED-D1/D2)

The SRAM RED eTap AXS (RD-RED-D1/D2) is the high-performance wireless rear derailleur that redefined 12-speed road drivetrains. Built on the revolutionary AXS platform, it offers a level of personalization and performance that is as intuitive as it is fast. The D1/D2 generations feature the Orbit fluid damper system, a specialized silicone-based damping technology that keeps the chain quiet and secure without the friction of a traditional mechanical clutch. With its sleek carbon cage and ceramic pulley bearings, it is engineered for the weight-conscious racer. Whether you're navigating a smooth time trial or a chattered gravel transition, the RD-RED-D1/D2 delivers consistent, lightning-fast shifts in any condition.
