XX Downhill CL56.5 Crankset

What Our Gearhead® Experts Are Saying:

"On 83mm downhill frames, the CL56.5 is the right call. The 56.5mm chainline aligns perfectly with 157mm hubs, and the DUB DH spindle gives it a planted feel. The shorter lengths help avoid pedal strikes in deep compressions and off-camber sections."

For dedicated downhill frames built around 83mm bottom bracket shells and wider rear hub standards, the XX Downhill CL56.5 Crankset delivers purpose-built alignment and durability. Engineered around a 56.5mm chainline using the DUB DH spindle platform, it supports both 157mm OLD and compatible 148mm gravity frames while maintaining optimal drivetrain positioning.

The robust aluminum arms feature machined reinforcement in high-wear zones and rock-strike prone surfaces, extending service life through aggressive race use. Progressive crank lengths—165mm, 160mm, 155mm, and 150mm—allow riders to tune pedal clearance and weight balance for steep terrain and high-speed compressions. Designed to pair with a dedicated T-Type chainring for gravity riding, the system integrates seamlessly into SRAM’s Transmission ecosystem for reliable chain retention and uninterrupted power transfer. For riders focused on full-gas downhill performance with maximum impact resistance and precise chainline alignment, the CL56.5 configuration is built to meet the demands of modern gravity racing.
