Speed and traction Aggressive file tread, or super low-profile knob design? The Terreno Dry bridges the gap between file treads, and traditional all-conditions treads. The key to this is the unique angled “fish scale” design, that allows the center tread to roll extremely fast, yet offer traction when loaded in cornering and braking. Add the transitional height mid and side tread, and the Terreno Dry transitions as smoothly as it rolls. From gravel grinding to medium conditions cross racing, the Terreno Dry offers consistent performance.

Whether in gravel or cyclocross, one thing is for certain—course conditions are constantly changing. When you roll up to the start line, be confident knowing that you have the performance advantage of the Terreno Mix all-conditions tread. At the heart of the design is a fast-rolling center ridge, designed to minimize rolling resistance while still providing confident braking traction. Cornering and off-camber work is confidently handled by alternating open shoulder lugs. These lugs are shaped to allow a supple feel for pavement and hardpack surfaces while still offering a solid effective edge for grass and loam terrain. If you are looking for that one tire to do it all, Terreno Mix is your choice! - Open shoulder lugs for secure off-camber traction - Traditional tread profile for smooth transitions across a broad range of terrain

The Terreno Zero features a Corsa-inspired tread design for paved surfaces and hard-packed gravel. The smooth center rolls fast while the side tread "scales" provide durable bite when cornering and braking. - Designed for paved surfaces and hard-packed gravel - Graphene compound

The Strada is Challenge's go to tire for long days on the road. This all-condition tire combines a round profile that takes the sting out of rough pavement with a construction that provides maximum control and low rolling resistance. This handmade tubular combines a supple, 300TPI SuperPoly casing with natural rubber tread, and a seamless latex inner tube for improved comfort, confident cornering, and quick handing. The latex tube is lighter, thinner and more flexible than a butyl tube, increasing your comfort, lowering your rolling resistance, and helping to prevent flats. The tube also includes a removable core Presta valve. This tire includes PPS Ganzo, a lightweight and supple Puncture Protection System placed between the tread and casing to increase resistance to punctures.
