My beautiful 2011 Madone has had problems due to bad shop maintenance. Today my pedal fell off because they neglected to install an integral part - the cotter pin that holds the pedal on. Could have been a very bad accident if I had not noticed the wiggling & stopped to check. When I did, it fell off in my hands. They admitted it was their fault.

Previously, the wheel rim tape didn't meet (1/4" gap) and I had several blow outs - one exciting one as I was descending at 35MPH. They swear that the rim tape wasn't the cause but since I put a heavier tube in - no flats. I told them to check the bike over completely & they assured me that they had. Apparently not.

I'm not a mechanic & don't want to be. I want to ride a bike long distances. But I have lost confidence. Am I within my rights to ask for a refund? I'm sure it will be denied & I'll end up with a lawyer. The bike cost $7,500.

Or maybe this is a fluke & I should forget it & ride with crossed fingers? I know I tend to overreact, so need the calmer, more experienced heads of the TE sisters.
