Offset design with subtle lip characteristics for increased grip, speed, and high energy. Designed to maintain grip. When desired they can be slid predictably and smoothly to shed speed. These wheels will not slide right out the box because of their grippy sharp edges. Repeatedly sliding wears down the sharp lips allowing for smoother slides. For a more oriented 70mm wheel check out the Stimulus Freeride wheels. The 4 Presidents Longboard Skateboard Wheels are a popular wheel for speedboarding and technical quicker turning courses requiring the quick acceleration of a small wheel.
