CeramicSpeed bottom bracket which converts frames with external bearing cups originally made for 24mm axles to fit BB30 cranksets with a 30mm axle. Note that not all BB30 cranksets will work with this system. Examples of cranksets that will work: Rotor 3D+, Rotor 3DF, THM, Zipp.
CeramicSpeed bearings are handmade in Denmark and installed in aluminium cups made by European Rotor Components.
CeramicSpeed BB’s offer extremely low friction and longer lifetime. The unique CeramicSpeed ceramic balls are of the highest achievable quality and out-perform everything else in the market.
Spacers are not necessary for this product and the system is super stiff and efficient.
Our BB bearings are used by professional teams like Astana Pro Team, Pro Team Tinkoff-Saxo, MTN-Qhubeka, CULT Energy Pro Cycling and professional MTB team Superior-Brentjen and Team Specialized Racing.
