CeramicSpeed Ceramic Race Coated Bottom Bracket - Threaded to 24mm (Shimano) Info
The CeramicSpeed Ceramic Race Coated Bottom Bracket - Threaded to 24mm (Shimano) is built around a simple premise: less friction means more of your effort reaches the road. CeramicSpeed's Grade 3 Silicon Nitride ceramic balls are fitted into hardened steel races in dust-free clean rooms — a process designed to deliver a frictional loss of just 0.45 watts, which CeramicSpeed claims represents a saving of more than one watt over most standard threaded bottom brackets in this class.
The ceramic balls themselves are a meaningful engineering choice, not a cosmetic one. Compared to standard steel balls, they're designed to be 400% smoother, 128% harder, and 58% lighter — and more than 100% smoother and 15% harder than standard ceramic alternatives. That combination of surface finish and hardness translates to reduced rolling resistance and longer bearing life, so you're not just gaining efficiency on the first ride. The coated version adds a protective treatment to the races, extending durability in demanding conditions. Available in English or Italian threading to suit your frame standard.
