I'm by no means a bicycle mechanic, but I am mechanically inclined. (I swear!) And still, when I change a flat, say, it's always a great pain to put the rear wheel back on. The fenders do obscure my view, but even with the singlespeed, there's no guarantee things will align perfectly. Invariably, the brakes rub. Or the fenders rub. Or there's a new noise that wasn't there before.
This should be easy after two year's as a daily commuter, but it isn't. Am I being too impatient? Or is there a trick to help me through this very basic repair?
