First off, I am on a budget. I just picked up an old Trek 520 frame that I am trying to get running, and I was thinking of stealing the wheels off my current road bike. First question: is a 28 width tire wide enough? Keep in mind I only weight about 155lbs. I think the back wheel with a 28c tire might be fine, but the front wheel is radial laced, do you think this will flex too much? I plan on putting some front panniers on, so I'm pretty sure I will have to find a new front wheel unfortunately.
