I think the most important question to you who is going to fix the bike when it breaks down forty miles from your house or LBS?
Maybe you need a better bike. Ever heard of a cell phone? Maybe its just luck, but I have been riding for years and my bike has never broken down to the point of being unrideable(not including crashes). If my car, which is far more complex than a bike, can last for over 100,000 miles before needing ANY repair, I have the expectation that my bike can go 40 miles without leaving me stranded.
