Pairing motocross-inspired tread with one of the most advanced rubber compounds in the industry, the Martello G2. 0 Enduro 4C Tire provides the traction and stability needed to conquer seriously challenging terrain. From sun-baked hardpack straightaways to loose and rocky chutes, the Martello finds grip in a wide range of conditions, making it an ideal choice for your aggressive trail or enduro bike. Now, Vittoria takes the Martello's performance a step further with a revised Graphene 2. 0 compound and a new Trail TNT casing. Together, these changes improve grip in wet conditions while enhancing the tire's resistance to sidewall tears and pinch flats. Vittoria's new Graphene 2. 0 compound consists of four different durometers of rubber in the tread, each one strategically placed for the best combination of low rolling resistance, cornering stability, grip, and longevity. Graphene 2. 0 essentially takes Vittoria's original Graphene-infused compound and betters it in every way, with special attention given to improve wet weather performance. Pair this with the extra sidewall protection and pinch-flat resistance offered by the Trail TNT casing, and you've got a 27. 5+ tire that's ready for big days on big terrain.
