Description plus minus

The very fastest wheel on the planet – used to set multiple World Speed Records – including Pete Connolly’s blistering mark of 91.17 mph / 146.73 kph (Sept. 16, 2017 at The Top Speed Challenge in Quebec, Canada); and Mischo Erban's Official IGSA standup record of 80.83 mph / 130.08 kph (Sept. 30, 2010 in northern Colorado).
The 85mm by 52mm Seismic Speed Vent is molded around their 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.
