Question: I've broken a couple of spokes on my rear wheel and wonder if I should keep replacing, or if its time to rebuild the wheel.
I'm getting back into riding after many years off. Bought a used Specialized Allez with the intention of riding myself back into shape, then (if?) indulging in a little bike lust and buying something hotter. The wheels are ok, but not great. Richie hubs, Mavic medium profile rims (I dunno which models). fifteen guage spokes. After a 100 miles or so I broke a spoke on the cassette side. Replaced it, no biggie. 150 miles later I broke a second spoke, also on the drive side. Replaced that too. But now I'm wondering if this is an indication that either the spokes are too weak for my somewhat portly (195lb) frame, or if they were not tensioned properly, or if they are just old, or if 15 guage spokes suck. Wheel is good and true, and spokes all seem to be tensioned properly...judging by sound and feel not w/tensionometer.
Question is, is this likely to keep happening, in which case I should rebuild the wheel, or does this sometimes happen? I've broken spokes before, but usually on my mountain bikes when I've obviously stressed it with jumps and the like. My riding on this bike has been pretty vanilla, no jumping curbs or hitting potholes etc
Also: if I rebuild, should I used the same 15 guage, or should I go up to 14 gauge?
PS: I'm fat, but I'm not THAT fat.
