A bottom bracket built to outlast your frame - BB ALPHA features hardened stainless-steel races hand-built with grade-3 Silicon Nitride ceramic balls, custom-engineered seals and precision dust covers, delivering up to 500% better moisture protection, while still providing ultra-low friction performance. All CeramicSpeed BB ALPHA models are handbuilt in Denmark and backed by a lifetime warranty.
- Hardened Stainless Steel races offer exceptional corrosion protection and provide an optimal surface for the hand-built grade-3 Silicon Nitride ceramic balls
- Internal ball bearing race has been redesigned to provide additional support, allowing the bearing to better handle pre-load
- Custom-made light contact seals with stainless steel covering the backside strike the perfect balance between efficiency and protection, while offering the trademark low-friction CeramicSpeed performance
- Incredibly stiff POM plastic dust covers to now sit flush, making it increasingly difficult for debris to penetrate the dust cover and contaminate the bearing
