CeramicSpeed Ceramic Race Bottom Bracket - Threaded to BB30 Info
The CeramicSpeed Ceramic Race Bottom Bracket Threaded to BB30 solves a specific and common problem: you want to run a 30mm-spindle crankset in a standard threaded bottom bracket shell. Available in English (68mm) or Italian (70mm) threading, this adapter-style bottom bracket uses CeramicSpeed's Grade 3 Silicon Nitride ceramic bearings pressed into cups manufactured by Rotor — combining CeramicSpeed's bearing technology with a well-proven cup design.
The ceramic advantage here is measurable. Grade 3 Silicon Nitride balls are tested to be 400% smoother and 128% harder than standard steel balls, with significantly lower rolling resistance as a result. That means less friction at the pedals on every ride — and because ceramic is harder than steel, the bearings are also more durable under load. Fewer watts lost, longer service intervals.
