The Maxxis Aggressor is designed for high-speed modern mountain bike trails. Advanced knob shaping creates extra gripping edges, and reinforced side knobs offer enhanced stability when cornering at speed. The secret is Maxxis' Dual compound with low-rebound but high traction, to help you keep the rubber side down. An all-around trail tire excelling on everything from loose cross country race courses to heavy all-mountain riding. DoubleDown 120 TPI dual-ply casing offers great flat protection.
