OTOH, I have some Tufos, which are actually tubeless and seamless (no stitched seam) that will hold air literally for months. It is also not true that expensive racing tubulars all use latex tubes that lose air quickly; I have several Conti Sonderklasse track racing tubulars that cost over $100 each that have butyl tubes that retain air pressure for weeks. Also, tubulars can be safely run a lower pressures on the road because they are not vulnerable to pinch flats the way clinchers are. I run tubulars on my road bike's training wheels as well as all my racing wheels, and the last time I had a flat on the road was over 4 years ago, however, I have had several clincher flats on other bikes. I just finished changing out the tubular on my rear road training wheel after putting 4000 miles on it and wearing it down to the cords without getting a flat. The roads I ride on are not super clean and there's significant amounts of glass and sharp debris, especially at intersections. As to price, I don't pay any more for decent tubulars than for clinchers, typically less than $50. I just don't buy them at an lbs, where you're likely to pay way inflated prices and only once in my life have I ever paid more than $100 for a tire.

I'm not advocating the use of tubulars over clinchers for general casual road use, just trying to debunk some of the nonsensical myths that seem to emerge whenever this subject comes up.
