These ain't yer grandpa's tubulars:



You can get these in 25mm width and they are bulletproof. Also, tubulars don't get pinch flats the way clinchers do, which eliminates about half of the flats. You can safely run tubulars at much lower pressures than clinchers and they give a much smoother ride on rough pavement.

Just a counter argument to all the anti-tubie ninnies here, most of whom have never used them.
