Breaking chain
I just went throught this with my new chain. My local bike shop sold me a piece of junk chain breaker and it ended up being broken, not the chain. So I got out my air grinder and put a grindingstone on it and ground down the rivit tilll it was flat, then took a punch and hammer to it. After about 5-7 minutes of pounding, the rivit was out and the chain was the correct size.Remember that once the chain is shortened, it can't be lengthened. The proper way to measure is with the chain on the bike and the adjuster alll the way in.
I hope this helps.
