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 offers 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. - Center scales are ramped, providing a fast-rolling leading edge with sharp, effective braking and cornering edges - Progressive depth tread design offers smooth transitions between cornering lean angles - Revolutionary file-tread Gravel and Cyclocross race tire designed for a range of conditions

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, no matter the terrain. At the heart of the design is a fast rolling center ridge, which is 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. The exclusive 3C Graphene compound structure places 3 unique compounds where you need them most, adding to the performance. - Exclusive 3C compound construction featuring Graphene compound technology - Fast rolling center-ridge design - Open shoulder lugs for secure off-camber traction - Traditional tread profile, for smooth transitions, across varied terrain

The ultimate wet weather weapon Many a battle has been lost due to a lack of preparation. In Gravel and Cyclocross racing, having the right tires is often the critical difference between winning and learning the hard way. When developing the Terreno Wet tread, we worked with the top athletes to gather their wish-list of performance traits that would make the ultimate wet weather weapon. Versatility was the common thread. It had to roll like a race tire, corner on rails, and be virtually clog-proof. A tall order by any measure. The final product is a tread that performs unlike any other.
