Improving the performance of your Shimano rear derailleur is as easy as using CeramicSpeed Pulleys to optimize the efficiency of your ride. These pulleys are compatible with any Shimano 11-speed derailleur other than XT and XTR, reducing friction and increasing bearing life. CeramicSpeed’s goal is to produce less drag while adding more power transmission to the rear wheel. These 11-tooth wheels are sure to keep you moving at a faster and more efficient pace than with your standard derailleur.
These attractive gold pulleys contain the standard machined aluminum and consist of the standard CeramicSpeed balls for simple and reliable performance. Your set of pulley wheels will come with designated upper and lower pulleys which are marked with directional arrows so you can be sure to install them properly. The kit also comes with oil so you can properly care for your bearings and keep them running smoothly.
