BB ALPHA Road Bottom Bracket - Italian, 70mm, For 24mm/Shimano Spindle

CeramicSpeed designed the BB ALPHA Road Bottom Bracket to deliver unmatched durability and efficiency for riders who demand the best performance from every pedal stroke. Built for Italian-threaded frames with a 70mm shell and 24mm spindle compatibility, this bottom bracket combines precision engineering with race-proven ceramic bearing technology for a smoother, longer-lasting ride.

Hand-built in Denmark, the BB ALPHA uses hardened stainless-steel bearing races paired with grade-3 Silicon Nitride ceramic balls to minimize friction and maximize longevity. The custom-engineered light contact seals and precision dust covers improve moisture protection by up to 500%, keeping contaminants out and performance consistent in any riding conditions.

A simplified spacer tube and lightweight 7075 aluminum cups make installation quick and straightforward, while reducing overall weight by 10% compared to previous versions. The new bearing placement and stiff POM plastic dust covers add structural integrity and enhance protection from debris, ensuring that the BB ALPHA runs smoothly mile after mile.
