Boost drivetrain efficiency with the CeramicSpeed Bottom Bracket—precision ceramic performance for every frame

What Our Gearhead® Experts Are Saying:


“I run CeramicSpeed in all my builds—SRAM DUB on my gravel rig, Shimano on my aero bike. The difference is tangible: effortless spin, quieter operation, and measurable watt savings. Installation takes patience, but once it’s in, maintenance is nearly zero.”


Every detail of the CeramicSpeed Bottom Bracket is built for efficiency. Inside each anodized aluminum cup sits a set of ceramic bearings, hand-assembled and matched for minimal friction. These bearings are 100% precision-made in Denmark and run on hardened steel races that maintain near-perfect roundness under load.


Each version—T47, PF30, BB30, BB86, EVO386, Italian, or BSA—is tuned to its shell width and crank spindle, ensuring optimal chainline and stiffness. Options include Shimano 24mm, 30mm, Campy UT 25mm, and SRAM DUB 28.99mm spindles, giving riders the right fit for nearly any road or gravel frame. Coated versions extend bearing life even further, resisting corrosion and micro-pitting for thousands of miles.


From crit sprints to gran fondos, this is the upgrade that turns smooth into silent, and fast into faster. When every watt matters, CeramicSpeed makes sure none go to waste.
