CeramicSpeed's BB ALPHA is their longest-lasting bottom bracket yet, built to stay smooth and fast for years. BB86 (also called PF86) is the 86.5mm press-fit shell used on many Shimano-standard carbon road and gravel frames.

BB ALPHA technology

• Grade-3 silicon nitride ceramic balls running in hardened stainless-steel races
• Custom seals and precision dust covers, with up to 500% better moisture protection than previous CeramicSpeed bottom brackets
• Lighter cups and simplified spacer tubing: about 10% lighter, and easier to install
• Hand-built in Denmark with a lifetime warranty
• Supplied with 5ml UFO TECH bearing grease

Choosing the right version

Pick the version that matches your crank spindle (Shimano 24mm, SRAM DUB 28.99mm, or 30mm for Rotor, Race Face, FSA, Cannondale and similar) and your riding style. Road, Gravel and MTB versions are matched to each crank's chainline and spacing.
