Named after the white gravel roads surrounding the Tuscan region of Italy, the Challenge Strada Bianca Pro tyre is designed to dominate exactly that type of terrain. 36mm wide and delivering a super-low rolling resistance, its' purpose in life is to perform exceptionally well in gravel races and long distance events. With construction features that include the Double Puncture Protection System (PPS2) your tyre will be substantially less likely to get a flat.

What is an Open Tubular?
The Open Tubular is constructed using the same process, casing and tread materials as a standard tubular. The difference is that instead of sewing the casing together (closed), the sides of the tubular casing are folded around Aramid fibre cords to produce beads. This 'open' design performs like a tubular, yet conveniently mounts like a standard clincher tyre. If combined with a latex inner tube the ride becomes even closer to that of a tubular, offering excellent traction and cornering, low rolling resistance and shock absorption.
