Yesterday I picked up a Ross Eurotour at a garage sale with the intention of stripping it down to the frame for single speed conversion as it has steel wheels and the rear was in pretty bad shape. When I got it home and was about to start in on it, I realized it had a cupped BB and not quite as ideal for the conversion as I had first thought. So I decided to salvaged it as a geared beater. I changed out the rear wheel and got everthing working mechanically and then I noticed something else I had'nt caught initially. The front chairings freewheel on the cranks. I thought this to be pretty odd and can't really see any purpose it serves. Anyone familiar with this?
