SRAM Red AXS E1 Aero Power Meter Chainring Kit Info
The SRAM Red AXS E1 Aero Power Meter Chainring Kit builds the power meter directly into the chainring itself — no separate spider, no added clutter, just clean integration that keeps weight down and torsional stiffness where it needs to be. Designed for SRAM's direct-mount interface, it slots into a Red AXS crankset and delivers power data to a claimed accuracy of +/-1.5%, consistent across temperature and weather changes.
The aero tooth profile is shaped to reduce aerodynamic drag while SRAM's X-SYNC tooth geometry works to keep the chain seated under load and over rough surfaces. AXS connectivity means the unit pairs directly with the ecosystem you're already riding — firmware updates, calibration, and data monitoring all handled through the app. Available in 44t, 52t, and 54t to suit a range of gearing preferences.
