Ceramic Bearing Pulley: New upgrade design, with ceramic bearing, can reduce the resistance during cycling, which ensures fast and sensitive working. Improve riding efficiency.
Smooth Ride: Deep toothed guide wheel to reduce chain drop. Positive and negative tooth guide wheel can effectively inhibit the horizontal swing of the chain, so that the speed is more accurate.
Installation: These derailleur pulley set are very easy to install with an allen key by simply removing the screw that holds the pulley to the derailleur. Includes accessory for compatibility with 4mm and 5mm screw thickness. Do not over-tighten because it would increase friction with the rear derailleur reducing the bike jockey wheel performance
