In this article I will review the C-Bear OCM Ceramic Pulley Wheels for Shimano GRX-RD-820 12-speed rear derailleur on the Canyon Grizl CF SL 8 1-by. On the Canyon Ultimate CF SLX I’m also running a pair of ceramic pulley wheels.

C-Bear Ceramic Bottom Bracket for BB86/BB92
C-Bear is the official sponsor of the Lotto Soudal cycling Team since 2009, providing riders like Andre Greipel and Thomas De Gendt with ceramic bottom brackets and -derailleur pulleys. If a C-Bear bottom bracket is good enough to withstand the Gorilla’s power peaks during sprints, than it is certainly good enough for me.
