Shimano Road 12T/14T Ceramitech Pulley Set (set of 2)

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.

These pulleys are compatible with:

RX810 & RX812-series cages

RX815 & RX817-series cages

R7000-series 105 SS & GS cages

R8000-series Ultegra GS long cage only (mechanical)

R8050-series Ultegra SS & GS cages (Di2)

R9100-series Dura Ace (mechanical and Di2)

These pulleys DO NOT FIT 12spd R9200-series Dura Ace or Ultegra 8100-series group sets.

It's a mystery to us why major manufacturers ignore bicycle bottom bracket and derailleur pulley performance and continue to pump out under-performing products that sap wattage from riders who are working like mad to get faster. You have the BBInfinite bottom bracket with Ceramitechs already, and you've experienced the tremendous gains. It's time for another step forward toward your goal. Get the most out of your ride with this Shimano pulley set that includes 12T/14T road bike pulleys.

WARRANTY:

BBInfinite Ceramitech pulleys have a 1-Year warranty.
