I am literally jumping for joy! After years of wanting a set I've finally received a basically pristine condition set of Caramba Double Barrel cranks but, and its a big BUT, the chainrings it came with are a single piece! I wanted to run these on my new get around bike in a smaller gear and bash guard. I guess my question here is can I grind off the teeth on the big ring without being yelled at by my fellow preservationists? Or must I throw another $30 at it and get a new spider off Ebay?
