650B/27.5-Inch

The name Revolution explains it all: a tread design that rolls faster than a slick while providing traction in a range of conditions. Micro-effective edges form a staircase of grooves in the direction of cornering force and channel water away from the center. E-bike-compliant Graphene compound rolls fast and extends battery life, while a reflective sidewall stripe increases your visibility for oncoming motorists. The Solid Shielding puncture protection layer makes punctures a thing of the past. As with all Vittoria Tech Series tires, the mix of performance and durability add up to a great value! - Graphene compound is regulation-compliant for e-bike use - Reflective sidewall stripe for safety

Aggressive file tread, or super low-profile knob design? The Terreno 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. - Center "scales" are ramped, providing a fast-rolling leading edge yet sharp and effective braking and cornering edges - Graphene compound technology
