I've been scouring the threads and haven't seen my general question answered, so I figured I'd just ask. In advance, "sorry" and "thank you". At 35, I've recently re-discovered the 12 year old in me who knew how to tear apart and put back together bikes. And living in Chicago, my <8 mi. commute just makes more sense via bike. I've got two older bikes--dad's old schwinn that's older than me, and a hybrid that I bought new in '92--that have been converted to single speeds out of convenience (broken/substandard deraileurs were out of my league as a kid and remain that way today). But I'm having some trouble with rear wheels going out of true. I've broken a few spokes, and recently replaced a rear rim (cheaply) and now its out of whack too (after about 80 miles). First off, I'm a little over six feet tall and about 210 or so (fairly good shape, I'd like to believe). My commute is city streets and I try to avoid potholes and lift myself up when I hit bumps. I'm not racing to work, but I do keep my cadence up a bit. I'm not looking to spend a fortune on a wheel, but taking these in at $30 per visit is more depressing. What should I look for in a rear wheel? more spokes? Do deep v's help, or is that just for kids listening to Wavves? I don't care about a matching set, I'm all about utility. I'll pay for something that works, but not for something pretty. My LBS seems a little aloof around me. So I turn to you, world bicycling community, to guide me properly.
