BB ALPHA Road Bottom Bracket Bearing Kit - For BB30, Compatible with 30mm Spindle

The CeramicSpeed BB ALPHA Road Bottom Bracket Bearing Kit is designed for riders who demand lasting performance and efficiency from their drivetrain. Built for BB30 frames and compatible with 30mm spindles, it combines world-class bearing technology with rugged durability for smooth, consistent power transfer ride after ride.

Each bearing is hand-built in Denmark using hardened stainless-steel races and grade-3 Silicon Nitride ceramic balls—a combination that dramatically reduces friction and resists corrosion, even in harsh conditions. The result is a bottom bracket engineered to outlast most frames while delivering the low drag and responsiveness serious cyclists expect.

A redesigned internal bearing race increases support under preload, while custom light-contact seals and precision dust covers keep contaminants out without sacrificing efficiency. For riders chasing every watt and every mile, the BB ALPHA offers a performance edge that endures.
