The 85mm by 52mm Seismic Speed Vent is molded around our proprietary Energy Conversion (EC) hub – the first tall, wide hub seen in longboarding and still second-to-none. The 85mm tire provides downhill roll speed, while the weight-saving hub adds the quickness and agility of a smaller wheel, as well as enhanced rebound. Combined with lips designed for pure grip, the Speed Vent stands in a class by itself.
