SRAM RED AXS D1 DUB Crankset - 175mm - 50/37t

SRAM RED AXS Road Crankset – 50/37T

The SRAM RED AXS crankset is built around a key drivetrain innovation: smaller chainrings paired with a wider-range cassette. By shifting gearing range to the rear of the drivetrain, SRAM created X-Range gearing, delivering a smooth, consistent cadence with a tight 13-tooth gap across all chainring combinations.

Designed exclusively for electronic shifting, the RED AXS crankset delivers crisp, precise front shifts and can be easily upgraded to a power meter for performance tracking.
