BB ALPHA Road Bottom Bracket - BB86 For DUB Spindle

CeramicSpeed BB ALPHA Road Bottom Bracket - BB86 for DUB Spindle brings world-class bearing performance to riders who demand the lowest friction and longest service life possible.

Built around hardened stainless-steel races and hand-built grade 3 Silicon Nitride ceramic balls, the BB ALPHA offers exceptional corrosion resistance and reduced drag under load. The custom-engineered seals and precision dust covers provide up to 500% better moisture protection compared to previous designs, keeping contaminants out and performance consistent in all conditions.
