    I replaced both jockey wheels in my old RSX rear mech and it works much better now. The old plastic pulleys were sloppy and lacking in teeth. These ones guide the chain onto the gears better. Good news is they come with a small cylindrical shim so you can use them on both sizes of bolt. Mind you... Read more

    Worked perfectly for me. Note there's a little shim in the middle which may be required depending on your derailleur's bolts. Suggest you fit this at the same time as a new chain. The only downside is I chose to buy one where I should have got two.

    Pros: Very well made, really smooth bearings, and they look great. Cons: Too narrow to work with older 7 speed derailleurs. I had wanted to use these on a older 7-speed Shimano XT derailleur, but they're just too narrow. The old 7-speed components are much wider than new stuff. They installed on... Read more

It is noteworthy that when making changes is more accurate the jump chain. be... Read more

    Nice looking and finishing, good bearings, very lightweight. Has a inner ring to adapt to different screw sizes (5 - 6mm diameter). I bought this pulley for a bike with SRAM Apex group (LE ROUTE 3 2013) and found out it is not compatible. The SRAM derailleur has a smaller diameter fixing screw, a... Read more

    It looks great/stylish. The colour is great. It's lightweight. It's easy to install. It's better than the orginal that was made from plastic. I would like to have more information from the inner structure, for example from the bearings. It could have been bit cheaper. I bought also pedals for my... Read more
