Seismic Speed Vent 73m 77a Longboard Wheels
Choose Defcon formula for explosive speed and rebound with smooth, predictable grip-to-slip.
The 73mm by 54mm Seismic Speed Vent is molded around our proprietary weight-saving Energy Conversion (EC) hub – arguably the most advanced hub on the market. The 73mm diameter gives it the roll speed of a larger wheel, 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 is utterly unique among high-end wheels. Breakthrough performance for DH, GS, and beyond.
