XX Downhill CL55 Crankset

What Our Gearhead® Experts Are Saying:

"On 148mm gravity frames, the CL55 lines up perfectly. The 55mm chainline keeps everything centered, and the shorter lengths really help in technical terrain. It’s strong where it needs to be, and the T-Type compatibility keeps the drivetrain tight and predictable."

When we’re building a downhill or gravity-focused bike around a 148mm rear hub and 73mm bottom bracket shell, the XX Downhill CL55 Crankset delivers the precise chainline and strength we need. Engineered around a 55mm chainline using the DUB Wide spindle standard, it integrates cleanly into modern frame designs while maintaining optimal drivetrain alignment.

The aluminum arms are purpose-built for downhill impacts, featuring machined reinforcement in high-wear and rock-strike prone areas to increase durability without unnecessary bulk. The crankset supports progressive geometry trends and improved pedal clearance on technical tracks. Its T-Type chainring interface ensures seamless compatibility within the SRAM Transmission ecosystem, delivering confident chain retention and efficient power transfer. Optimized for gravity riding and compatible with 12-speed and 7-speed T-Type systems, the CL55 configuration is ideal for riders seeking balanced Q-factor, refined chainline, and uncompromising strength on 148mm-based builds.
