SKU: 115429
Brand: CeramicSpeed
Type: BB ALPHA Ceramic Bottom Bracket
A bottom bracket built to outlast your frame. The CeramicSpeed BB ALPHA is custom-engineered to precisely pair a 24 mm axle Shimano crankset (or other 24 mm spindle systems) with a pressfit 46 mm bore frame that is asymmetric and 79 mm wide, commonly referred to as BBright.
BB ALPHA features hardened stainless-steel races hand-built with Grade-3 Silicon Nitride ceramic balls, custom-engineered seals, and precision dust covers—delivering up to 500% better moisture protection while retaining ultra-low friction performance. The simplified spacer tube design and lighter cups ensure quick installation and a 10% weight reduction over previous generations. All CeramicSpeed BB ALPHA models are backed by a lifetime warranty.
