I am piecing a red sprocket and a gold chain together and found the chain on ebay a lot cheaper. This is not your basic gold chain its powder coated etc. What I need to know is how many links does it need to be to fit the 520 set up.+2 -1 46/15. The chain is 120 links. I need to know if I need to cut or no. Please dont give any guess answers or clueless feedback. I am trying to get this done
and only need knowledgeable answers PLEASE.:usa
