The Chris King R45 Ceramic XDR Driver is a direct-fit replacement freehub body for Chris King R45 hubs, built to accept SRAM's XDR 12-speed road drivetrain standard. Constructed with ceramic bearing interfaces, it delivers the smooth, low-resistance engagement that Chris King hubs are known for — with the durability to match long-term, hard use.

Chris King components are manufactured to tight tolerances in Portland, Oregon, and the R45 driver reflects that same standard. Designed as a service or upgrade part, it slots into the existing R45 hub shell without modification, making it a clean solution for riders switching to a 12-speed SRAM groupset or replacing a worn driver body.
