The Hope 12 Tooth derailleur pulley is milled from a piece of aluminum. The teeth of the lower and upper rollers differ in shape to ensure that the chain runs safely and quietly. The deep groove ball bearings have special seals for easy running.
The Hope 12 T derailleur wheels are machined from a single piece of aluminum. The teeth of the lower and upper rollers differ in shape to ensure that the chain runs safely and quietly. The ball bearings have special seals for easy running. Labyrinth seals in the spacers also prevent debris from entering the bearing. This and the large ball bearings ensure low-friction, long-lasting operation.
The wheels are suitable for SRAM and rear derailleurs, which are 11-speed compatible. Not suitable for SRAM derailleurs with integrated roller holders (2-point mount ). Road gear derailleurs from SRAM partly have an upper roller with a 4mm screw hole.
