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.
