It's getting frustrating how expensive bicycle maintenance is. I'm starting to wonder if pedaling isn't cheaper than driving to work if you already own a car.

Is it normal to get 1-2 broken spokes in your rear wheel almost every month? It costs like $15-$25 to get get 'em fixed at the bike shop and I don't think it's worth it anymore. Or if you need a wheel trued, that's another charge.

So what gives? This is on a 2011 Trek 7.2 FX. I only ride the thing like 20-30 miles a week if that, but almost every month or so, it's the same thing. A broken spoke (or several) in the rear wheel. Back to the bike shop and another $20+ dollars down the drain. Is this normal???
