Tubular tyre

A tubular tyre, referred to as a tub in Britain, a sew-up in the US, a single in Australia, or just a tubular is a bicycle tyre that is stitched closed around the inner tube to form a torus. The combination is then glued (sometimes with two-sided tape) onto a specially designed rim, referred to as a "sprint rim" in Britain, and just a "tubular rim" in the US, of a bicycle wheel.

The combination of a tubular tyre and its tubular rim is lighter than that of a clincher tyre and clincher rim, and will therefore always result in less rotating mass or a stronger construction. Tubulars can also be used over a wider range of tyre pressures from 1.7 to 14 bar (25 to 200 psi), compared to the typical 6-9 bar on a clincher tyre.
