Maybe I should be asking the roadies this question but I'll try here first. I have recently been introduced to the heaven and hell of riding tubulars (I impulsively bought a Campy Shamal front wheel on ebay). The heaven of riding them and the hell of dealing with a flat. My question is: does anyone else use tubulars on their daily ride and if so is there a tire you are using that has adequate puncture protection to deal with urban riding. I really don't want to give up riding tubulars but changing a flat is such an ominous (and expensive) chore I couldn't imagine doing it more than once every six months at the least.
