Description

The Last Bottom Bracket You'll Ever Need

Ceramic Speed Alpha (BSA) Bottom Brackets deliver their trademark low-friction performance, while boosting durability and introducing a simplified user experience, setting an unprecedented industry standard for bottom bracket performance. The BB Alpha is the result of a complete overhaul of their previous design, where each individual product element was meticulously examined and optimized to create the best bottom bracket on the market; a claim they stand by with their ultimate Lifetime Warranty.

The BB ALPHA project didn't arise from a need to fix any issues, but rather from Ceramic Speed's relentless pursuit of perfection. They set out with four goals:

  • Make the new BB lighter
  • Make it even more durable
  • Enhance simplicity in the design
  • Not compromise on friction reduction

A Complete Redesign

The new design boasts increased durability through improved seals, optimized dust cover interfaces, and naturally corrosion resistant Hardened Stainless Steel races. So you can ride longer without maintenance needs.

It's been fully optimized across the board to minimize weight with refined cups in a new stronger alloy and an updated spacer tube design. Which means riders get maximum efficiency in a lightweight package providing peak performance without drawbacks.

And then they tested it and refined it until it was perfect. The Alpha has more than 1,000,000 test kilometers covered in the lab and in the field, with input from pro teams across cycling disciplines, like Soudal Quick-Step, PAS Racing, Yeti-Fox Factory Racing, and Cannondale Factory Racing.

Features:

  • Covered by Ceramic Speed Lifetime Warranty
  • 10% lighter than previous CS BBs
  • Hardened Stainless Steel race material paired with CeramicSpeed Balls
  • Custom designed seals proven to increase protection from moisture and contamination by 500%
  • Custom designed dustcovers, optimized for fitment and protection
  • Cup material and design optimized for strength and reduced weight
  • Superlight spacer tube design with fewer variants for greater simplicity
  • Shimano 24mm or SRAM DUB
  • Road or Gravel seals
