C-Bear Shimano OCM Ceramic Hybrid Pulley Wheels

C-Bear’s Shimano OCM Ceramic Hybrid Pulley Wheels offer an easy and significant upgrade over the stock pulley wheels as they fit within the existing cage so no need to replace it, hence the Original Cage Max moniker. With 12 and 13 teeth per wheel, they are larger than the 11 tooth Shimano wheels and so require less articulation from the chain and therefore create less friction. Coupled with this benefit is the use of C-Bear’s ceramic bearings, leading to greater durability and less drag in the drivetrain, giving more speed for less effort.
