CeramicSpeed CCD EVO derailleur pulleys for Shimano Ultegra and Dura-Ace 12-speed groupsets are designed for riders using one of these groupsets who want to upgrade their bike's drivetrain. The cage is made from 100% 3K carbon, with a custom thickness and a protective matt finish. The 7075 aluminium pulleys run on fully ceramic bearings, with both ceramic cages and balls, and the rear bolts are titanium.
The claimed weight is 70 g. To choose, check your rear derailleur: the set is compatible with Shimano Ultegra RD-8150 and Dura-Ace RD-9250, both 12-speed. The recommended cassette has a maximum of 34 teeth, and a chain with 2-4 more links than a standard chain is recommended with these pulleys. This version is black.
