I was originally very happy with this set that I bought about 6 months ago. They are light and look good. However after I switched to a larger cassette, I noticed the teeth were close to going into contact with the larger cog. I removed them and sure enough the diameter is slightly larger than my standard Ultegra. Then I checked the bearings and they were completely shot... Bottom line my old ultegra pulleys went straight back in (still rolling smooth after 2 years)

Looks great but install was a bit tricky.

Comments about KCNC Bike KCNC Ultra 11 Tooth Derailleur Pulley:

It looks really good but during install it could only go one way otherwise it would cause the chain to come off and jam on the rear derailleur. A little too much "slop" I'd say.

Works well. The bearings are smooth and seem​ to be a good replacement for the stock jockey wheels when they wear out.

Inconsistent?

By Peter

from Nevada City, CA

Comments about KCNC Bike KCNC Ultra 11 Tooth Derailleur Pulley:

Just mounted and took a ride. Feel smooth, look great. However, when I took two of the pulleys out of their boxes, one felt definitively smoother than the other. I had a child and wife verify my suspicions. I mounted them both up anyway because I hate unfinished projects. But in the back of my head, I'll know that one of those pulleys is dragging more than the other. (Built in excuse for being OTB?)

          A:

          Yes, the derailleur pulley is narrow and will work on an 11 speed chain.
          It should work on a 12 speed chain as well.

          I am not sure as I used it on a 10 speed bike chain.  Best thing to do is count the teeth on your current pulley.
