Aspen core with strategically placed pre-bent birch laminates (to re-inforce sidewalls). This core is lightweight, super strong and built to take the abuse of the core freestylers. * 25 degree ABS sidewalls increase power transfer over the edge and helps protect the core. All ABS sidewalls are polished to perfection. * Our sidecut radius is a segment of two circles (transitional). They work in harmony with our core profile for balanced performance and progressive pressure distribution. * NanoTech with Struc Turn High Speed sintered 7500 base. The fastest base in the industry (with StrucTurn). Period. The IS7500 sintered base is mixed with graphite, black carbon and Nano additives. The Nano additives take in heat then expel the heat to melt the snow.
