Hey bike forums members, I've got a problem and was wondering if you could help me out. I'm in college (NDSU, Fargo, ND) getting into my first non-bigbox store bike. I've determined a road orientated hybrid or cyclo-X (with emphasis on the X bike) bike to fit my needs perfectly. The problem is, I want to make sure if I'm spending a bunch of money, I get a bike that fits me right. I'm 6'5", 37" inseam, and I weigh 235 lbs. I've been to my lbs and sporting goods stores and most of them stock Giant, Trek, or Specialized bikes in 22.5" or 61cm frame sizes. I test rode an XXL specialized tricross that I liked a lot but it was only 61 cm and I'd really like to give a 25" or 63cm a shot before I make any final decision (mostly because I'm afraid I only like these bikes because they are bigger than Wal-mart ones and not actually my size). Am I just being overly picky? on lbs tried to tell me something about specialized bikes being "more proportional" as they get bigger, any validity to that? Are there ways to make a bike "ride bigger?"

Thank you, I look forward to your replies
