Hey everyone, I'm looking for a Campagnolo Nuovo Record pista chain ring 50 tooth or bigger. In fact 52 would be ideal, would rather not go much bigger, but let me know what you got. Nothing ridiculous please. I'm trying to do this on a limited budget and its going on a rider not a show bike, so scratches are fine (if not encouraged) as long as the teeth are in good shape. Let me know what you got! Isaac Schell Brooklyn NY
