SRAM XX T-Type Downhill CL55 DUB MTB Crankset Tuned for the descent Built for the heaviest demands of downhill racing and riding, the SRAM XX DH Transmission crankset focuses on strength-to-weight where it counts the most. The XX DH Crankset's robust aluminum design takes inspiration from the groundbreaking X0 alloy crank, and focuses on downhill strength and performance. The XX DH Crank features a durable machined finish in high-wear zones and common rock-strike areas for a long-lasting finish and increased durability. The crankset is also available in progressively short crankarm lengths all the way down to 150mm, for increased trail clearance and a more modern fit. This is paired with the already-robust SRAM Transmission chain and drivetrain technology. This purpose-built crankset is built for riders who want to push their limits on the descents, and need a crankset that can help them get there.
