So dumb question about tire widths...
Aside from trial-and-error, how do I find out what tire widths my bike can handle? I recently tried monkeying around with a set of 700x42s on my 2007 Redline Conquest Pro, only to find that while the front was okay, the rear tire was rubbing up against the chain stays. Now I'm worried that it won't be able to handle anything larger than a 700x32 tire, but I'm not exactly eager to spend money on new tires only to find that they can't fit.
