Discover the bike wheel bearing kit you need for your rim brakes. Our selection includes options for the DT Swiss 240, Mavic Kysrium SL/Cosmic SL, and Mavic Kysrium SR/R-Sys/Carbone. The Ceramitech bicycle wheel bearing replacements feature grade 5 balls and precise internal tolerances for smooth rolling. With low-contact seals, our bearings have much lower friction than other steel bearings with standard seals. Made with a corrosion-resistant steel, our bearings resist ceramic-induced wear and help you avoid parasitic drag. Our bearing kits are designed to replace every bearing in your wheel set to ensure you experience an efficient ride every time.
