Sram MTB 12T Ceramitech Pulley Set (set of 2)

  • Rock solid chain control means crisper shifts while Ceramitech bearings channel all your hard work to the trail.

    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 a chain up and down a cassette caked with mud and grit. Delrin shrugs off wear that grinds aluminium pulleys into nothing, which is why Shimano and Sram both use Delrin in their own pulley sets. The Ceramitech bearings are in-molded for absolute security and durability as well as ease of maintenance.

    These Ceramitech Sram 12T pulleys blow stock pulleys away when it comes to spin, and the oversize diameter reduces chain pin working angles to eliminate every bit of friction possible. The aggressive tooth pattern clears debris from the system rapidly and efficiently to prevent mis-shifts and unintended chain derailments.
