SRAM RED AXS Power Meter Crankset - 175mm 12-Speed 48/35t Direct Mount DUB Spindle Interface Natural Carbon D1. The SRAM RED AXS power meter is a huge step forward in power meter design giving riders the gearing they truly want and need. Shifting performance has been optimized by moving the range from the front of the drivetrain to the back and creating a consistent 13-tooth gap across all variants of chainring duos. The crankset is designed specifically for electronic shifting with Quarqs premier DZero power measurement technology fully integrated.
