Start with a World Championship proven TNT bead, add the proprietary 4C Graphene compound, and top it off with a moto-inspired tread design with progressive width siping and you have the Vittoria Martello Enduro TNT tire. This last part is key, and provides for a progressive feel on the effective edge, allowing for that fine-touch tactile feel that top racers expect. Whether shredding rocks, roots, or mixed terrain, Martello delivers!
