I am a big guy (245lbs) and ride a single speed. I popped a spoke on my rear wheel from mashing up hills, getting out of the saddle and swinging the bike side to side. I took the wheel to a trusted LBS and got the same story about probably breaking more spokes. The guy talked me into letting him build me up a 36 spoke rear wheel, old school with a free wheel. Surly hub, Velocity rim and DT Swiss spokes. It cost me some money but I am really happy with how it turned out. This wheel is bomb proof, no more broken spokes and I'm not worried about giving it all I've got on the hills. I don't regret this investment at all.
