SRAM RED AXS D1 Quarq Power Meter Crankset 172.5mm 46/33T DUB 2x12-Speed
The SRAM RED AXS D1 power-meter crankset combines hollow carbon crankarms with an integrated Quarq DZero power meter and one-piece aluminum chainring assembly. This flagship road crankset is engineered for low weight, high stiffness and accurate performance measurement.
The spider-based Quarq power meter measures total power, cadence and left/right power balance with an accuracy of ±1.5%. Temperature compensation maintains consistent readings as riding conditions change, while ANT+ and Bluetooth connectivity support compatible cycling computers and mobile devices.
SRAM’s 46/33T X-Range gearing provides a broad usable range and smoother progression between gears. The consistent 13-tooth difference between the chainrings is engineered specifically for fast and reliable SRAM AXS front shifting.

Please note: This is the original D1 version, not the newer E1-generation crankset. The D1 power meter and 46/33T chainrings form an integrated assembly. If the chainrings become worn or a different gearing combination is desired, the complete compatible power-meter and chainring assembly must be replaced.
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, gearing, chainline, bottom-bracket standard and drivetrain compatibility before purchasing.
