RED Direct Mount Aero Power Meter Chainring

What Our Gearhead® Experts Are Saying:

"The RED AXS Aero Power Meter Kit has been my go-to for both training and racing. With the power meter housed directly in the chainring, it’s lighter and stiffer than traditional setups. It’s dead simple to set up with SRAM DUB systems and provides consistent, accurate data—even when conditions get unpredictable."

When we push for our personal bests, we demand equipment that keeps up—and SRAM’s RED AXS Aero Power Meter Kit delivers every time. By fully integrating the power meter into a direct mount chainring, SRAM slashes weight and increases stiffness, ensuring that every watt we produce is accurately captured with a tolerance of just +/-1.5%. Whether chasing PRs or pushing limits in variable conditions, this unit doesn’t flinch.

This aero-optimized design pairs beautifully with SRAM 12- and 13-speed drivetrains and is fully compatible with all SRAM Road DUB bottom brackets. With X-SYNC wide-tooth, narrow-tooth profiles, it keeps chain engagement secure even under aggressive efforts. Connectivity through both ANT+ and Bluetooth means seamless integration with head units and apps, while firmware updates are a snap through AXS.

Offered in a range of sizes from 56t up to an incredible 68t, the RED AXS Aero Power Meter Kit fits a spectrum of riding disciplines, from road racing to time trials and triathlons. No matter the event, this precision instrument helps us perform at our absolute peak.
