Jan,

The Campagnolo 5 speed chain guide is a stock item. I had 5 of them I bought from Euro-Asia back in the late 70's. Unfortunately, I haven't any left that I can find. I was just talking about these things the other day with someone, but I forgot who. They are great for TT bikes of the "old style" where you ride your road bike with a single chainring and a bunch of light parts and wheels.
