Couldn't load pickup availability
CeramicSpeed CCD EVO S derailleur pulleys are designed to replace the rear derailleur pulleys on bikes with a Shimano Ultegra or Dura-Ace groupset. They are compatible with Ultegra RD-8150 and Dura-Ace RD-9250 12-speed derailleurs, or Ultegra RD-8000/R8050 and Dura-Ace RD-9100/RD-9150 11-speed derailleurs. The cage is made from 3K carbon fibre with a matt finish, the pulleys are 7075 aluminium and the bearings are full ceramic.
The blue colour is an aesthetic choice and does not change the technical specifications. Before ordering, check your groupset and number of speeds, as compatibility is the first selection criterion. A maximum cassette size of 34 teeth is specified for optimal adjustment and shifting. The warranty covers the carbon cage, aluminium pulleys and ceramic bearings for 4 years.
