The very fastest wheel on the planet – used to set four World Speed Records, including the Official IGSA standup record of 80.83 mph (130.08 kph), set by Mischo Erban on Sept. 30, 2010. The 85mm by 52mm Seismic Speed Vent is molded around our proprietary weight-saving Energy Conversion (EC) hub – possibly the raciest, sexiest hub on the market. The 85mm diameter gives it the roll speed of a downhill 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 longboarding, downhill, GS, and even Hybrid slalom.
