The Seismic 85mm x 52mm Speed Vent wheels are molded around a proprietary Energy Conversion (EC) hub, allowing for a combination of tall and wide hub first used in longboarding and still second-to-none. The 85mm urethane tire provides good downhill and flat land roll speed, while the EC hub adds the quickness and agility of a smaller wheel. Especially useful for LDP and long distance skateboarding since you roll faster with each push or pump. Combined with lips designed for pure grip, the Speed Vent stands in a class by itself.
The Seismic Speed Vents 85mm longboard wheels comes in 3 three proprietary formulas;
BlackOps™: ultimate balance of speed and grip • extreme traction fresh • buttery and smooth broken-in • comfortable and predictable
Defcon™: Guinness WR speed • directional slide • long-lasting grip • slow, consistent wear
Premium Clear™: the best beautiful clear urethane on the market • smooth, fast, and grippy
