I'm 6'2"-6'3" and about 240 lbs. I'm looking to get rid of my hybrid for a "real" bike. Would I be better off buying a cyclocross bike, with its fatter tires, etc., than a traditional road bike? I'm worried about crushing wheels, blowing tires, etc.
The bike would primarily be used as a commuter on some rough roads in Philly (lots of potholes, strewn with debris, etc.), although I also plan on riding a number of miles on regular, smooth roads.
What do you guys think?
