Red GXP 12-Speed Crankset

What Our Gearhead® Experts Are Saying:

"When I upgraded to the SRAM RED AXS Crankset, the biggest difference was how fluid the shifts felt under pressure. I’m running the 50/37t with a 10-33t cassette, and it gives me the punch I want on sprints without sacrificing climbing range. Plus, the crank’s stiff carbon arms make every watt count, especially on steep pitches."

SRAM’s RED AXS Crankset sets the gold standard for modern road drivetrains, integrating top-tier materials and groundbreaking gearing to meet the needs of elite riders. With its carbon crank arms and direct-mount chainrings, this crankset delivers high torsional stiffness and ultra-low weight—perfect for aggressive efforts on the road or race circuit. The GXP spindle interface ensures compatibility with legacy bottom brackets while still maintaining efficiency and stiffness.

What truly sets the RED AXS Crankset apart is its implementation of X-Range gearing. SRAM reduced the chainring sizes and expanded the cassette range, moving the work of cadence balancing to the rear and optimizing the front for quick, smooth shifts. The result is a consistent 13-tooth gap between rings and intuitive gear steps that minimize cadence disruption. Riders can fine-tune their drivetrain experience with a wide array of chainring options: 46/33t, 48/35t, and 50/37t, all direct mount and ready for power meter upgrades.

It pairs seamlessly with SRAM’s eTap AXS wireless groupsets, integrating perfectly into both aero and traditional frame designs. With crank arm lengths in 170mm, 172.5mm, and 175mm, this crankset meets a range of fit needs, and its 45mm chainline is optimized for modern disc brake road bikes. Ideal for competitive riders or enthusiasts looking for elite performance and personalization, the RED AXS Crankset ensures smooth power delivery, optimal gearing, and a future-ready upgrade path.
