What Our Gearhead Experts Are Saying:

“I swapped my stock BB for a CeramicSpeed setup and immediately noticed the difference—less drag, more spin, and that signature ceramic smoothness. The precision machining makes installation simple, and the long-life grease keeps the bearings running quietly through rain, grit, and long climbs.”

We count every watt on the road, and CeramicSpeed’s Bottom Bracket helps us keep more of them. Designed in Denmark and built for serious riders, each bottom bracket uses hand-polished ceramic bearings that reduce friction and last far longer than traditional steel options. Whether we’re running SRAM DUB, Shimano 24mm, or 30mm spindles, there’s a CeramicSpeed fit for nearly every modern frame standard.

Machined alloy cups house ultra-smooth bearings packed in all-weather grease, ensuring quiet, consistent performance through years of training miles and race days. Threaded or press-fit, coated or standard, every option shares the same focus: unmatched efficiency and minimal drag that turn every pedal stroke into forward momentum.

Smooth every pedal stroke with the CeramicSpeed Bottom Bracket—engineered speed, lasting efficiency (DWGC9KF)
