Good news everyone!
A while back I sold an XL mountain bike frame to a guy who said he was going to turn it into a cross machine. It sorta made me wonder whether or not he was going to put some 700C wheels on it. It had pretty decent tire clearance, and a 26" mountain bike tire probably comes pretty close to what a 700c cross tire would be in terms of overall diameter right? Is this something that's commonly done? If so I may start looking for a cheapo mountain bike frame. I also figure I should look for a frame that slightly larger than what I'd normally ride on a mountain bike right? I guess I could also just buy a 29er mountain hardtail but they aren't as abundant.
