Derailleur Pulley
Derailleur pulleys play a big role in drive train performance. These small wheels have the fastest spinning bearings of a bicycle.
To guarantee the lowest friction possible, 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 do not require 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 the precise shifting and smooth performing. All pulleys are available with choice of PA66+GF plastic or 7075 T6 aluminum body.
