CeramicSpeed BB ALPHA Bottom Bracket - T47 73mm For 24mm/Shimano Spindle MTB BLK

The CeramicSpeed BB ALPHA Bottom Bracket is built to outlast your frame. With hardened stainless-steel races, hand-built grade-3 Silicon Nitride ceramic balls, and precision seals, it delivers moisture protection and ultra-low friction for a drivetrain that stays smooth mile after mile. Handbuilt in Denmark and backed by a lifetime warranty, this bottom bracket redefines endurance on rugged MTB routes while shedding weight with lighter 7075 aluminum cups and a simplified spacer design.

Riders seeking a dependable upgrade will appreciate the renewed efficiency and reduced maintenance this bottom bracket provides. By moving the bearings outward within the cups, debris-detecting seals sit flush and resisting contaminants becomes easier, ensuring your power transfer remains consistent on challenging terrains.

Who is this for?

This is for riders who demand long-term reliability, minimal maintenance, and superior smoothness from their MTB drivetrain. Ideal for enthusiasts upgrading a 24mm or Shimano-spindle setup on a T47 shell, athletes tackling steep climbs, fast descents, or mixed-terrain adventures will benefit from the low-friction performance and robust construction.
