Skiing requires a certain amount of trust in your equipment. Trust that it will perform and trust that it will keep you safe. The Thunderbird R13, with its all new Trueblend Piste woodcore and Active Carbon Armor vibration damping system, is designed to give you that trust and confidence to carve turns as fast as you dare on any groomed piste, and with a 13m radius, to have the ability to rip short turns like a pro.
