Get your grind on with the Ripstik G extreme grinding machine! The RipStik G Caster board blends the skateboard, surfboard and snowboard for a riding board that that is unlike anything youve seen! This innovative ride features a spinning aluminum G-tube in the center for smooth grinding action. The unique twisting motion of the caster board allows you to accelerate and turn without having to push off the ground! In fact, your feet never leave the board. The 360 degree inclined caster trucks and pivoting deck offer you an intense, snowboard-like carving ability. The concave deck provides increased foot control so you can learn to shift your weight and steer. The tough urethane wheels and ABEC 5 speed bearings ensure a smooth ride on almost any surface while the tough deck supports up to 220 lbs.
