From Tiagra to Dura Ace, we've got you covered with these Shimano pulleys. Add some serious performance and make a statement with a flash of color. Or go stealth black. No matter how you go, you can't go wrong.
Compatible with the newest Shadow derailleurs from the Ultegra 8000 series to the Dura Ace 9100 series. Compatible with all Di2 and mechanical systems.
Ceramitech Derailleur Pulleys are designed to eliminate a major source of drive train drag from your bicycle. These are an ultra-high performance racing part designed to give you an edge on race days. We recommend changing the pulleys every 4,000 miles, or about the life span of two chains, for maximum reliability and performance.
Make no compromises. Studies have shown that frictional loses at the derailleur are not merely fractional losses. 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 seen the gains. It's time for another bump. Get the most out of your ride by riding ceramic derailleur pulleys.
