These are nice alloy 10-tooth CNC'd jockey wheels for many vintage and some modern derailleurs. The bearings are sealed for a long and smooth life. The kit includes bushings to accommodate most derailleur's through-bolts.
I like the sealed bearings, and the spacers work great. Very good quality

Sealed bearing jockey wheels
The wheels themselves are nice, but the spacer set did not include spacers that would work on Simplex derailleurs, and I had to struggle to install them.

perfect ten
ten tooth wheels are not a dime a dozen .........so far these wheels are working great .....shifting is just like new on this 30 year old schwinn mirada with thousands of miles on it
