CeramicSpeed BB ALPHA for BSA Shimano Road

 

Product Introduction

A bottom bracket built to outlast your frame. The CeramicSpeed BB ALPHA features hardened stainless-steel races hand-built with Grade-3 Silicon Nitride ceramic balls, delivering ultra-low friction performance with up to 500% better moisture protection through custom-engineered seals and precision dust covers. The simplified spacer tube design and lighter cups ensure quick installation and a 10% weight reduction over previous generations, bringing the net weight down to just 81g. Every BB ALPHA is backed by CeramicSpeed's lifetime warranty.

Precisely pairs a 24mm axle crankset from Shimano (including Dura-Ace, Ultegra, and 105 series) with any BSA or English threaded 68mm frame.

 

Product Features

Lifetime Warranty
Every BB ALPHA is hand-built at CeramicSpeed's factory in Denmark, passing rigorous quality inspections before being backed by a lifetime warranty. This level of confidence comes from knowing the product is engineered to last longer than the frame it's installed in.

Ultra-Low Friction
Grade-3 Silicon Nitride ceramic balls are rounder, harder, and lighter than traditional steel balls, dramatically reducing rolling friction. More of your pedalling power translates directly into forward motion — a difference you'll feel on long rides and steep climbs.

Corrosion Resistant by Design
Hardened stainless-steel races eliminate rust and corrosion at the material level. This is particularly critical for riders in Hong Kong's subtropical climate, where high humidity and coastal salt air can quickly degrade standard bottom brackets.

Exceptional Bearing Protection
Custom-designed dust covers refined through 28 iterations, paired with purpose-built seals, deliver 500% better protection from moisture and contamination compared to conventional designs. Rain rides, bike washes, and wet road conditions are no longer a threat to your bearing longevity.

Lightweight & Serviceable Design
Optimised cup materials and a super-light spacer tube deliver a 10% weight saving over previous CeramicSpeed generations, with the complete unit weighing just 81g. The bottom bracket is fully serviceable — periodic cleaning and re-greasing keeps it performing at peak efficiency indefinitely.
