Couldn't load pickup availability
The NRC CCD EVO jockey wheels 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 customised thickness and protective matt finish. The 7075 aluminium jockey wheels run on entirely ceramic bearings, including both the cage and balls, and the rear hardware is titanium.
The stated weight is 70 g. To choose, check your derailleur: the set is compatible with the Shimano Ultegra RD-8150 and the 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 jockey wheels. This version is black.
