Derailleur pulleys are a crucial component of your bicycle. Pulleys right from the factory have a ridiculous amount of drag that causes you to work harder without going any faster. Ceramitech pulleys are here to change that. Welcome to the future of speed at BBInfinite.
Select the maker of the rear derailleur you have:
For ALL 10 or 11 speed Shimano road bicycle derailleurs with a short cage or mid cage, mechanical or Di2, select "Shimano 11T". The 11T's will work with any Shimano road system no matter what.
For newer Shimano groups such as the R8000 series or the Dura Ace 9100 series or any "Shadow style" rear derailleur, you should consider going to 12T's or even the huge 12T/14T's (yes, they fit) for maximum performance.
For ALL Sram non-1X road rear derailleurs, short or long cage, 10 or 11 or 12 speed, mechanical or eTap, select the “Sram 11T” or the "Sram22/eTap 12T" button above. On most of these you can run either 11T or 12T, depending on how big you want the pulleys to be.
For ALL Sram 1X road rear derailleurs, 11 or 12 speed, mechanical or eTap, select the “Sram Road 1x 12T” button above.
For ALL Campagnolo rear derailleurs, short or long cage, 10 or 11 speed, mechanical or EPS, select the “Campagnolo 10/11 spd” button above.
