I have a nice tubular wheelset which I want to use for street use in philly (and soon to be nyc) and want to know what I should put on there for maximum flat protection. I wanted to just change out the rims but I couldn't find a rim with the same spoke length needed as mine (mavic GL-330). The set currently has one tire mounted which holds air, its a continental sprinter. So my options are buy one more of those for 40$:
or get a pair of these vittoria CX tubulars for 80$.
the CXs look like the tread wouldn't provide too much rollign resistance although I'm sure the continentals would be faster. The bike is an old skool conversion so I'm pretty sure I'd have enough clearance. I guess pinch flats aren't the issue with tubies so would the CX tires be considerably more puncture resistant?
