The CeramicSpeed BB ALPHA for BB30 (Shimano 24mm Road) is engineered to precisely match Shimano and other 24mm axle road cranksets with BB30 frames featuring a 42mm press-fit bore and a 68mm shell width. Built on the completely redesigned BB ALPHA platform, this bottom bracket is designed to outlast your frame while delivering CeramicSpeed’s signature ultra-low friction performance.
At the heart of BB ALPHA are hardened stainless-steel bearing races, hand-built with Grade 3 Silicon Nitride ceramic balls, offering exceptional corrosion resistance, long service life, and consistent efficiency. Custom-engineered low-contact seals and precision dust covers increase moisture and contamination protection by up to 500%, ensuring smooth performance even in demanding conditions.
A simplified internal design with lighter cups reduces weight by 10% compared to previous generations and allows for faster, more straightforward installation. Handbuilt in Denmark and backed by a lifetime warranty, BB ALPHA sets a new industry benchmark for bottom bracket performance.
