Rock solid chain control means crisper shifts while Ceramitech bearings channel all your hard work to the ground.
This Shimano ceramic pulley set features a 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.
This Shimano ceramic pulley set blows the stock pulleys away when it comes to spin, and the oversize diameter reduces chain pin working angles to eliminate every bit of friction possible.
