It's the best tool to help you reach your best. Our lightest, stiffest, and most accurate integrated power meter just got lighter with a new carbon crankarm construction. Our power meter is accurate to +/-1.5% and isn't affected by temperature changes, and the direct mount X-SYNC chainring is aero and incredibly long-lasting. Plus, we're offering more crank arm lengths than ever before to ensure this crank works for you.

Technical Features
Quarq
Quarq technology powers all of SRAM's power meters, including the SRAM RED eTap AXS power meter. Power meters calculate power by measuring the torque (pedal force) and the angular velocity (cadence). Power = Torque x Cadence. SRAM power meters use a proprietary strain gauge arrangement and precision digital circuitry to deliver high accuracy and low power consumption for optimal battery life.
