🔧 Shimano Derailleur Pulley Set, 1 Pair, compatible with 6, 7, and 8-speed drivetrains Review

I had to replace my old worn out derailleur pulleys and they fit perfectly. It was very easy to take off the old ones and put on the new ones.

Does not fit my long cage Shimano 105 8 speed rear derailleur. "Narrow" pulleys are required. It's "wide" although it doesn't say so in the description.

I replaced my old worn ones and they worked great. Unfortunately, the washer that came with the rear gear didn't fit. I ended up using the one from my old set and everything worked fine.

I have used this particular pulley set for many thousands of miles for many years. If your chain is worn and you change it, you should also change these pulleys. I like this set because it is easy to install and works well for a long time.

It was difficult to find the right idler pulleys for my derailleur model as there are maybe thousands of them? Styles and sizes so I just took a chance and hoped it would fit. The quality and shipping was good and would have earned 5 stars but I took a chance and lost it so I donated it to a local bike shop who quickly replaced me.

The blocks are OEM equivalent but they don't fit my switch. I have a 10 year old Shimano Deore 8 speed narrow cage and they were 1.5mm thicker. Although I haven't used them, they appear identical to mine except they are not stamped "narrow". A few local bike shops can't find a source for the narrow wheels either. So if the top part gets wobbly enough, it's either a new derailleur or a new bike.
