Vittoria's new heavy-duty enduro performance is here. The Vitoria Mostro is a downhill and enduro tire tested and proven by professional riders. The dual-ply, 120TPI casing ensures protection and support when we bomb down gnarly trails, and the 4C Graphene rubber compound, which uses four different rubber compounds, throws down impressive traction and grip in all scenarios. The Mostro is tubeless ready, so we can ditch the tubes and set it up tubeless for more traction and less weight. Additional sidewall protection gives us more support as we rail through berms.
