Yeah - that's what I thought. Seriously - I'm 6'2" and around 270 pounds. I'm riding 700c skinny wheels and I have no problems. I have been riding since I was over 400 pounds and have never broken a spoke. I've never had custom wheels built. Even the low-end stock wheels on my Trek 7200 have never given me trouble and I've taken them on MTB trails! I suspect it's because they are kept tensioned properly and the tires themselves are kept inflated properly.
