This pulley kit is designed specifically for Shimano GRX derailleurs RD - RX810 and RD - RX815. Both the guide and tension pulleys are equipped with precision sealed bearings. These bearings ensure a smooth and friction - free drivetrain, which is essential for a great cycling experience. Compatible with GRX 11 - speed and GRX DI2 series, this kit is a perfect upgrade for your bike.
Using this pulley kit is easy. First, remove the old pulleys from your Shimano GRX RD - RX810 or RD - RX815 derailleur. Then, carefully install the new pulleys from the kit. Make sure they are properly aligned and tightened. When riding, you'll notice a smoother drivetrain right away. As for maintenance, regularly clean the pulleys with a mild bike cleaner and a soft cloth. Check the bearings for any signs of wear every few months. If you notice any unusual noise or resistance, it might be time to replace the pulleys. Keep the pulleys dry to prevent rust and corrosion. And always store your bike in a dry place to extend the life of the pulleys.
