11T SRAM/Shimano Ceramic Hybrid Bearing Jockey Wheel Pulley Set for SRAM 10/11Speed Road/MTB, Shimano 10/11 Speed Road/MTB Cyclocross Gravel Rear Derailleur

This is one only good product out there if you want to replace your worn out pulley wheels. The install process was simple and well instructed. I suggest anyone who wants to replace their pulley wheels to buy this instead of the OEM part since it will work with your derailleur and will also last longer than the OEM part.
