CEMA Derailleur Pulleys | SRC-JW-B024-CF Aluminum Full Ceramic, 10/11-Speed

Derailleur Pulley
Derailleur pulleys play a big role in driving train performance. These small wheels have the fastest spinning bearings of a bicycle. To guarantee the lowest friction possible, the CEMA JW series installed the fastest spinning bearing we had available for industrial customers: CEMA's ZrO2 Full Ceramic Bearing. Due to ZrO2 material properties not requiring any grease or seals, the bearings can spin freely and are near-frictionless with a lifetime exceeding any other bearing type.

Assembly with G5 Si3N4 Ceramic Ball, you can enjoy precise shifting and smooth performance. All pulleys are available with a choice of PA66+GF plastic or 7075 T6 aluminium body.
