All I can say is that either Canadians have REALLY bad tubulars or REALLY good clinchers! In fifteen years of racing tracks all over the world, I think I've had two flats -- and I've never ridden clinchers. And the tires I've used have ranged from $10 road training pieces of **** to $250 Conti Olympics. (I think one flat was a wide cotton Wolber that blew because I'd been riding it on cords, and the other was a silk Clement that blew out a sidewall around the valve. One of the loudest sounds I've heard in my life!)
OTOH, I don't think I've ever seen a clincher go flat on the track, although I come from a time when hardly anybody rode clinchers on the track.
Now that I think about it, I've probably seen a dozen flat tires resulting from riding on the track in my whole life. There just shouldn't be any reason to puncture on the track. Do they have brooms in Canada?
