Shimano 10/11 spd Road Ceramitech Pulley, Lower Only for Brompton


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.

These pulleys are compatible with:

5700-series 105

7000-series 105

6800-series Ultegra

R8000-series Ultegra (mechanical and Di2)

R9000-series Dura Ace (mechanical and Di2)

R9100-series Dura Ace (mechanical and Di2)

...and many more.

It's a mystery to us why major manufacturers ignore 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. Improve the performance of your bike with these Shimano pulley wheels. Get the most out of your ride by riding Shimano ceramic derailleur pulleys.


BBInfinite 11T Ceramitech pulleys have a 1-Year warranty. Set these up with our pulley covers for maximum use!
