Challenge Strada Pro 700x25C tire

Thanks to its finely woven carcass, the folding tire has almost the same driving characteristics as racing tubulars. It impresses not only with its performance, but also with its comfort with a 25 mm wide tread. A lightweight and flexible extra layer built under the tread reduces the risk of punctures by thorns or stones.
