I'm a 23yo clyde (6'. 255lbs) just getting into cycling. I broke my back a few years ago, and put on a lot of weight in the recovery period and following year or two, when I was mostly sedentary. My lbs has a bianchi volpe from 2006 which is on sale at a pretty nice price, $675 for my size. The wheelset is a combination of tiagra hubs, and alex ACE 19 36h Rims. They seem pretty solid, but i think i'm going to swap out at least the tires for some 28mm road tires, and I might swap out the wheelset if it isn't strong enough. Any suggestions for wheels, or do you think the stock setup would be pretty solid? Also, any good puncture resistant tire suggestions that come in a 700x28 size?
