Pulley wheels are the fastest spinning bearings on your bike. An upgrade to C-Bear full ceramic bearing therefore is the most effective Speed upgrade.

C-Bear's new 12 speed Shimano mountain bike pulley's are an easy fit straight into the derailleur sharing the same smooth tooth 13T Lower pulley design as the factory spec making for an easy smother upgrade to your drive train.
