I bought a Cannondale and rode it for about 150 miles without any problem, and then switched over the SRAM group to my Blue. After the swap, the bike rides for about a mile or two and then suddenly my chain breaks. This has happened about three times and I have tried all sorts of remedies and none of them seem to work. It seems to happen when I put stress on the chain, such as going uphill or pedaling harder. I was just wondering if any one knew what may cause this or have had this problem?
Thanks
