I set out today for a 20 to 40 mile ride. Right after I made the turn where I chose the 40 mile route instead of the 20 mile one, I broke a spoke on my rear wheel, so I loosened the back brakes, turned around, and rode gingerly home for a 21 mile ride. Last summer and early fall I was breaking spokes right and left. The mechanic at the bike shop rebuilt the wheel with DT spokes, and it has held up until now. When I had the bike in in January, he checked the wheel, and it was still true. Another guy at the shop thinks the stock wheels on this Trek hybrid (2200) are just not durable enough for the miles I'm putting on it. If I start breaking spokes again, I may have to decide whether to put a better wheel on the bike or use the money for a new bike.
