That's what I was going to say. Perhaps the OP should work on losing about 30 pounds via healthy eating so he feels comfortable getting back on the bike, and then start working on exercise again. Personally, even though I've never owned a CF bike I think he'd probably be fine, but if there's still a lingering concern then focus on weight loss for a few months first.
