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.
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
