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
