Aggressive file tread, or super low-profile knob design The Vittoria 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 centre 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.Material: Nylon 20 TPICompound: 2CDiscipline: Gravel / CyclocrossBead: Rigid or FoldingColour: BlackETRTO: 37-622Weight: 721g (approx.)
