C-BEAR OCM Shimano 11-speed/Ultegra 12-speed Derailleur Pulleys

The OCM Shimano derailleur pulleys from C-BEAR work with ceramic ball bearings that run in steel grooves. They are compatible with the 11-speed rear derailleurs of the Dura-Ace R9100, Ultegra R8000, GRX and 105 R7000 series as well as with the 12-speed Ultegra R8150 rear derailleur. They are larger than the original derailleur pulleys. This way, the performance of your drivetrain can be significantly increased.
