Unconditional Satisfaction GuaranteeNo Shipping Fees Above 302 Months to Decide. Returns Simplified.The SRAM RED Carbon crankset paves the way for a fundamental design innovation called X-Range: smaller gears and a cassette with a larger ratio. This results in smoother, faster front shifting and more usable gears for today’s riders. The new possible configurations improve cadence and efficiency and ensure crisp, clean and fast shifting. The SRAM RED Carbon cranks are completely hollow thanks to Exogram technology. The X Range Direct Mount gears harmonize perfectly with the Yaw technology of the RED eTap AXS derailleur to deliver exceptional, low-friction shifting. Like the current SRAM MTB cranks, the SRAM RED crank arm is also equipped with the universal DUB (Durable Unified Bottom Bracket) crankshaft which can be used in all common crankcases. It also increases stiffness. The bearing play is regulated by an adjusting ring.
