All-mountain riding calls for a tire that walks a fine line in between cross-country and enduro. To start, you need something more robust than the featherweight XC hoops, but without the heavyweight commitment of an enduro-minded tire. Vittoria's Agarro G2. 0 Trail 4C Tire aims to please with a balance between the two, providing considerably more grip than the Barzo cross-country tire, but without enduro bulk of the Martello. It offers leading edge steps, which work similarly to a ramped lug, but provides better climbing grip when things get technical and steep. Progressive sipes offer tactile grip on rocks and roots, which is particularly advantageous when things start to get a little slick. Vittoria employs its 4C Graphene 2. 0 compound on the Agarro, which utilizes four different durometers of rubber in the treat, each one stratigically placed for the best combination of low rolling resistance, cornering stability, grip, and longevity. Graphene 2. 0 takes Vittoria's original Graphene-infused compound and betters it in every way, with special attention given to wet-weather performance.
