The Challenge Strada is the ultimate tyre for long days in the saddle and serious rides. It's perfect for riders who want high performance without running a fragile race-day only tyre on all-day adventures. The incredibly fast-rolling herringbone tread offers excellent cornering control. The 300TPI SuperPoly casing provides an incredibly smooth and supple ride. This tyre features a handmade tubeless folding bead casing with PPS Ganzo puncture protection and a smart rubber compound for excellent grip and durability. The Strada is built for comfort and speed while still being durable and grippy. The herringbone tread helps it roll incredibly well while still offering excellent control under braking and while cornering, even in the wet. It is equally at home during the winter and is not just for dry days; it's happy enough in the wet as well. Built around Challenge's legendary 300TPI SuperPoly casing, the Strada offers an unbelievable smooth ride, meaning even on longer stage races, you won't feel beaten up, and it can even help transform otherwise stiff riding bikes into something far more comfortable and compliant. If you want the ultimate long-distance road tyre, the Challenge Strada is the perfect choice! Specifications: Best For: Road/TT/Tri/All Road. Construction: Handmade. Series: PRO. Size: 700.
