Shimano 11 Speed Road Pulley Options (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 wheel 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.

All 9,10, and 11 speed Shimano systems and all SS and GS variants of these systems, EXCEPT: Not recommend for GRX-series RX810 or RX815 derailleurs.

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.
