SRAM XX DH Crankset, FC-XX-DH-A1

The new XX DH Transmission crankset delivers uncompromising durability and performance Drawing on the experience gained from our best aluminium cranks, SRAM has developed these DH-specific cranks from the ground up, offering a first-class balance of stability and weight. The robust crank arms, featuring milled surfaces in areas particularly prone to wear and rock impact, are available in progressively shorter lengths of up to 150 mm. This ensures the cranks look as good as new for as long as possible. With its significantly higher impact resistance and torsional stiffness, the completely new XX DH T-Type chainring for the 56.6 mm chainline easily meets the highest demands of DH racing.

SRAM DUB DH Axle Bottom Bracket System:

The DH MTB cranks have a 4.5 mm longer axle than the previous DUB Wide MTB Boost cranks. The SRAM DUB DH cranks are suitable for standard downhill bottom bracket shells with a 83–107 mm installation width. The axles have a diameter of 28.88 mm. Axle play is adjustable via a preloader. The SRAM DUB cranks have a completely proprietary standard and are only compatible with DUB bottom brackets, not with other standards or bottom brackets.

SRAM Direct Mount T-Type Chainring:

The teeth feature the T-Type Narrow Wide profile. This prevents the chain from coming off, even without a chain guide. Compatible only with SRAM Wide cranks and T-Type chains from the Transmission series. The T-Type Direct Mount chainrings are bolted directly onto the crankset using the 8-point bolt pattern. The 8-point bolt pattern is also compatible with SRAM Quarq power meter spindles. Specially developed for the Eagle T-Type chain and drivetrain, it offers significantly quieter performance and exceptional durability. Dirt is removed more easily. The chainring teeth are longer and shaped like a saw blade to engage perfectly with the Eagle chain. The new chainring profile thus increases chain tension and pedalling efficiency. At the same time, friction, chain noise and wear are reduced.
