The new SRAM DUB crank standard, built on a 28.99 spindle, allows for a more contamination resistant BB design, while retaining the ultra-efficient & long-lasting qualities CeramicSpeed Bottom Brackets are known for.

With an integrated dust cover for all models, a snug & secure fit that also fully protects the face of the bearing delivers exceptional performance without any sacrifices. CeramicSpeed hand-built bearings carry the load from crank to frame with un-paralleled durability & efficiency.

The SRAM DUB crank spindle requires the bearing contact points to be in a set and designated width and all CeramicSpeed bottom Bracket options perfectly match the bearing placement on the crank spindle with the required frame interface for nearly any model of bike. Without the use of unnecessary adapters or spacers, a quiet & stable platform is ensured throughout the life of the product.

The BSA for SRAM DUB Road comes in two versions; with our CeramicSpeed Standard Bearings and Coated Bearings for even longer lifetime and lower friction.
