Seismic Speed Vent 73mm


The Speed Vents are one of Seismic‘s classic race-winning (and world record setting) downhill wheels. Much like the 75.5mm Alpha, these use Seismic’s special Defcon urethane and a giant core to get the most speed possible out of your setup – only these are a little skinnier and a little lighter, making them great for any situation where acceleration is key.

73mm tall x 54mm wide Speed Vent Wheels:

  • 53mm running surface
  • Offset bearing seat
  • Square outside edge, beveled inside edge

Poured in Seismic’s proprietary Defcon™ formula:

The 73mm by 54mm Seismic Speed Vent is molded around their proprietary weight-saving Energy Conversion (EC) hub – the first tall, wide hub seen in longboarding and still second-to-none. 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 stands in a class by itself.
