Hi all, need some info from all you roadies out there, for the last year I've been cycling to work on my flatbar hybrid, and since I'm hooked on cycling thought I would get myself a road racing bike, but have a couple of questions. 1. Racing bike wheels being only 23mm wide do they buckly? and 2. do they puncture easily? will I spend most of my time fixing punctures and tightining spokes?
