CeramicSpeed Bottom Bracket

CeramicSpeed Bottom Bracket

CeramicSpeed utilizes Grade 3 Silicon Nitride balls that possess the best possible surface finish and roundness. In testing, the balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls found in most bike components. They’re more than 100% smoother and 15% harder than standard ceramic balls. The balls are installed into hardened steel races in dust-free clean rooms and then checked again before assembly is complete. Not only is low friction the result, but so is increased bearing life. Like three to five times longer than standard bearings.

Another step they take in assuring the lowest-possible frictional drag is using grease they designed as lubricant. It comes in the bearings and a syringe comes with the bearings as well.

The cups have been manufactured by Rotor. The bottom bracket width is 68mm or 73mm for the English-threaded versions, 70mm for the Italian-threaded. The spindle diameter is 24mm, meaning that FSA’s 24mm and Rotor’s 24mm spindle-diameter cranks will fit as well. Included with the kit are: bottom bracket, dust cover, grease, and sticker sheet.
