SRAM RED AXS E1 Quarq Power Meter Crankset 175mm 46/33T DUB 2x12-Speed
The SRAM RED AXS E1 power-meter crankset combines ultralight hollow carbon crankarms, X-Range gearing and an integrated Quarq power meter in SRAM’s premier road crankset. The E1-generation carbon construction is lighter than the previous RED design while maintaining the stiffness required for racing and high-performance road riding.
The Quarq spider-based power meter is integrated directly into the one-piece 46/33T chainring assembly. It measures total power, cadence and left/right power balance with an accuracy of ±1.5%. Temperature compensation helps maintain consistent readings as riding conditions change.
SRAM’s 46/33T X-Range gearing provides a broad climbing range while retaining small, consistent steps between gears. The 13-tooth difference between the chainrings is engineered for fast and reliable front shifting.

Please note: This is the standard 45mm-chainline road version, not a DUB Wide crankset. A compatible SRAM Road DUB bottom bracket, pedals and installation tools are not included unless specifically pictured.
This is a genuine SRAM OEM component and may be supplied without retail packaging. Please review the listing photographs for the exact included hardware and cosmetic condition. The CR2032 battery is a consumable item, and its remaining service life is not guaranteed.
Professional installation and initial power-meter pairing or calibration are recommended. Please confirm crank length, chainring gearing, chainline and frame bottom-bracket compatibility before purchasing.
