1 status for 2 weeks) proved that the performance gap had been narrowed.

Still, to this day, the choice of most professionals is tubulars.

Cheap sew-ups fail easily because their low-thread-count casings are very fragile.

The ride quality is still pretty good, but I think this partly attributable to the flexible, supple design of a box tubular rim. They make an intermediate step between cheap tubulars and often staggeringly expensive hand-made sew-ups.

At least one clincher tire company wanting to have its tires favorably compared to tubulars has started counting both the warp and weft (sometimes called "woof"). Higher thread-count casings are stronger, lighter, more flexible and more expensive. The technique of inflating the casing then hand gluing the tread onto the casing. It is generally accepted that in the 19th century Charles Goodyear discovered that by cooking natural rubber with sulfur he could create a long-lasting rubber that had an almost infinite variety of uses.

It will be flat, looking almost like a thick strip of cloth. The tread was vulcanized to the flat fabric of the casing.Yet the sales volume, hence the money, is in clinchers.So a large number of pros are paid to use clinchers. As noted above, for years the only choice for a high performance cyclist was tubular tires.While not up to tubular performance, they were good enough for most riders who had long dreamed of being emancipated from the difficulties of tubular tires.Rim manufacturers developed lightweight rims that would sustain the high tire pressures that heretofore had not been needed for clinchers.

A wide array of tubular equipment, both in rims and tires, was available and avidly used by performance riders. Repairing a flat is difficult because the casing must be unstitched, the tube patched and then the casing re-sewn. This must be done with care so that under hard cornering the tire doesn't roll off the rim.
