What Our Gearhead(R) Experts Are Saying: "I've been running the 27. 5in Martello Trail on my mid-travel trail bike, and it's been awesome. It's got moto-style bite for rough terrain but still spins up fast when you're earning your laps. Feels planted on roots, rocks, and hardpack."When the trail demands control, precision, and speed, the Vittoria Martello Trail 27. 5in Tire answers with race-proven performance and all-mountain versatility. Designed as the lighter, more efficient sibling of Vittoria's enduro tire, the Martello Trail brings big traction to smaller wheels for a nimble, responsive ride. Its moto-inspired tread pattern digs deep in dry or mixed conditions, while progressive siping across the knobs fine-tunes flexibility for a glued-to-the-trail feel without sacrificing rolling speed. The 4Compound Graphene rubber formulation delivers balanced grip, durability, and rebound control. Backed by the reinforced Trail casing and anti-puncture belt, this tire shrugs off rim strikes and sharp edges, giving us confidence to push harder through rough terrain.
