The CeramicSpeed BB ALPHA is built to outlast your frame. This version pairs SRAM DUB 28.99mm axle cranksets with EVO386 press-fit frames — a 46mm bore, 86mm shell width, with bearings placed inboard.

Grade-3 Silicon Nitride ceramic balls and hardened stainless-steel races deliver ultra-low friction and exceptional longevity. The sealing system underwent 28 design iterations, achieving 500% better moisture and contamination resistance. A simplified spacer tube design ensures quick installation and a 10% weight reduction over previous generations.

EVO386 is a press-fit BB standard using a 46mm bore and 86mm shell width, commonly found on frames from Cervélo, Argon 18, and others. It belongs to the 46mm press-fit family alongside BBright and PF30, but differs in shell width — always confirm your frame spec before purchasing.

Every unit is hand-assembled in Denmark and backed by CeramicSpeed's lifetime warranty.
