Good quality and pretty easy to fit, depends that on your particular set up though I guess.. Much of an improvement over the extremely worn out ones that were on my bike. Don't forget the drivetrain parts (chain, crankset, cassette or freewheel) will not wear in isolation, so if your pulleys are pretty worn and the rest of the drivetrain has not had attention, then it's probably all due to be replaced as I did.

Both pulleys are the same. Originally on my bike the guide pulley (G pulley) had a fixed center piece that was in metal. This one does not. It is all plastic. The other parts are ok. The cylinders that goes in the pulley's center and dust caps are in metal and the right size.

Genuine Shimano jockey wheels at an excellent low price. I would recommend packing the bearings with moly grease as it will keep them lubed for ages and stop any water getting in.

It has the look and feel of a genuine Shimano product.

Counted number of teeth on jockey wheels to ensure direct replacement. Works well. Amazing what a difference changing jockey wheels makes to the drive chain.
