We got these nifty 10-tooth alloy jockey wheels. They come with shims to fit many derailleurs. Modern derailleurs use 11-tooth wheels, so it's getting hard to find replacements for vintage derailleurs. The bearings are sealed for a long and smooth life. The through bolt must be smaller than 5.1mm in diameter.
By the way, we also have a Tumblr. Cool pictures of stuff we like.

These look great! Any chance they'll be available in other colors, like silver, black or gold?

I doubt we'll have them in other colors. This is one of those items that we felt there was a need for, but realistically, we know we won't sell many. It makes little sense for us to carry a lot of extra inventory since there in a fairly high minimum production quantity for each color.
Do you happen to know if these will fit a 70's Campy Neuvo Record?

That particular derailleur is a 1970 model. One washer on each side did the trick.
Isn't the key thing with jockey replacement sprockets (aside from fitting between the cage) is really that the two wheels have the same number of teeth to ensure an even feed rate of chain?
The comment about 10t versus 11t in the post description to me is more an aesthetic, historical accuracy issue rather than one of practical necessity. That said, these do look nice!
My understanding is that the standard went from 10 to 11 because an odd number of teeth wears more evenly (wide/narrow links always engage the same teeth with a 10-tooth pulley.)
I also have a question: does the jockey pulley have a bit of play such that it imitates the Shimano Centeron G and similar indexed system pulleys?
@mauricio,
These jockey wheels have a bit of lateral float.
