SRAM’s lightest stiffest and most accurate integrated power meter just got lighter with a new carbon crankarm construction. The SRAM RED AXS 1x Aero E1 Power Meter Crankset 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 they’re offering more crank arm lengths than ever before to ensure this crank works for you.
