Handmade ceramic bearings installed in aluminium cups.
For T47 frames with 86mm shell width and SRAM DUB cranks with 28.99mm axles.
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.
High quality spacers for different housing sizes included.
Every single bearing is hand built in Denmark under clean room conditions. All parts are selected by hand for perfect fit, each bearing is spun by hand multiple times during the building process to ensure that all parts are matched perfectly.
CeramicSpeed balls are smoother, harder and lighter than the standard steel balls which are typically used in bicycle components.
