BBInfinite Ceramitech Pulley (SET OF 2) Blue

10/11 Speed Shimano Road Pulleys. Rock solid chain control means crisper shifts while Ceramitech bearings channel all your hard work to the ground.

Each cog set features DELRIN® 510GR construction, a fiber reinforced polymer specially suited to high strength situations where resistance to deflection is paramount, such as every time you shift. The Ceramitech bearings are in-molded for absolute security and durability as well as ease of maintenance.
