BB ALPHA Road Bottom Bracket - BB86 For 24mm/Shimano Spindle

Built for performance and longevity, the CeramicSpeed BB ALPHA Road Bottom Bracket – BB86 for 24mm/Shimano Spindles delivers a smooth, efficient ride with unmatched durability. Designed to outlast your frame, this bottom bracket combines precision engineering with premium materials to reduce friction, resist corrosion, and protect against the elements.

Hand-built in Denmark, each BB ALPHA uses hardened stainless-steel races paired with grade-3 Silicon Nitride ceramic balls for exceptional smoothness and strength. The new bearing layout pushes the bearings further outboard, improving stiffness and sealing performance. Custom light-contact seals and precision POM dust covers keep contamination out without adding drag, ensuring consistent performance in all conditions.

A simplified spacer design and lightweight 7075 aluminum cups make installation straightforward while trimming 10% off the weight compared to previous generations. Riders benefit from lower friction, better protection, and long-lasting reliability for countless miles on the road.
