The Challenge Strada Bianca Pro Open Tubular Clincher Tyre gives you the performance characteristics of the tubular version but with the added assurance of greater options if you happen to puncture.
The white gravel roads throughout the Tuscan region of Italy, the strade bianche, are the inspiration for these tyres from Challenge. Designed to handle that type of terrain, the 30mm width and super-low rolling resistance ensure they perform exceptionally well in gravel races and long distance events.
With construction that features the Double Puncture Protection System (PPS2), your tyre will be less likely to get a flat.
What's an open tubular?
An open tubular is constructed using the same casing and tread materials and process as a tubular, but 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.

Designed for use on rough roads, cobbles, hard-packed dirt or for bigger riders
Higher pressures allows for a very supple ride
