Shimano Road 12T Ceramitech Pulley Set (set of 2)


Size Guide

  • 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.

    Ceramitech 12T Shimano Road pulleys blow 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.

    Compatible with:

    ULTEGRA R8000

    DURA ACE 9000

Get the most out of your ride by riding Ceramic derailleur pulleys
