The choice of professional riders since many years of victories on classic races and many podiums have proven
Criterium is Challenge finest pro-racing tire.
The Criterium 320 Clincher relies on its proven tread pattern in order to provide both low rolling-resistance and incredible grip. Longitudinal ribs run down the center, with a herringbone structure on either side. And like the good old days, this legendary tread pattern is still glued by hand to the casing after the casing has been tensioned. The logic behind this is that, when a tread made separate from the casing, it rides better and with less rolling-resistance. The reason behind this is that it doesn't get deformed by the inflation of the tire.
Below the tread, Challenge applied its classic corespun cotton casing. Essentially, this means that the casing fibers are made by twisting staple cotton fibers around a central filament core, creating one yarn from multiple fibers. As a result, the material is between 40 and 50% stronger than typically spun materials, while retaining a similar, if not lower, overall weight. This results in a thin, light, and flexible case that is super-supple. The thread count is 320 threads per inch (TPI), which is the highest in the Challenge line. This not only creates the smoothest ride available in a clincher design, but it also contributes to the Criterium 320's low weight (200g per tire).
And to provide protection against flats, a thin corespun polyester belt -- the same material that makes the casing -- is sandwiched between the casing and the tread. It's also glued on when the casing is under pressure. Challenge calls this its Puncture Protection System (PPS), giving a little added protection under the tread while leaving the sidewalls thin and supple.
