The SRAM Quarq Rival Power-Upgrade AXS E1 is a spider-based power meter designed to seamlessly integrate with your existing SRAM Rival AXS crankset. Built on Quarq’s proven technology, it delivers accurate, consistent power data from both legs, helping you train smarter, pace efforts precisely, and track your progress over time.

This power-upgrade is engineered to work smoothly within the SRAM AXS ecosystem, pairing wirelessly with compatible head units and apps for effortless setup and data viewing. It typically offers features like automatic temperature compensation and robust sealing against the elements, so your numbers stay reliable in changing weather and on long rides. Whether you are fine-tuning intervals, dialing in race pacing, or simply wanting deeper insight into your rides, the SRAM Quarq Rival Power-Upgrade AXS E1 provides a straightforward, elegant path to adding high-quality power measurement to your road or gravel bike.
