Available in crank lengths from 160mm to 175mm, the Rival E1 ensures precise fit for riders of all sizes. The aluminum crankarms and chainrings maintain long-term reliability while supporting SRAM’s advanced drivetrain features like Road-Yaw front derailleur technology and Road Flattop chain compatibility. Finished in sleek black, the Rival AXS E1 Crankset delivers a high-performance, aesthetically refined solution for 12-speed 2x drivetrains—combining innovation, shifting excellence, and exceptional value.
