Seismic Skate Systems Speed Vent BlackOps Clear Purple Skateboard Wheels - 85mm 79a (Set of 4)

The Seismic Speed Vent Skateboard Wheels is 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 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 Downhill, LDP, carving and cruising.

  • Wheel Size: 85mm
  • Durometer: 79a
  • Color: Clear Purple
  • Contact Patch: 52mm
  • Offset bearing seat

How to Buy Skateboard Wheels

What size diameter skateboard wheels do you need?

Skateboard wheels vary in color, size, and durability. Skateboard wheels are most commonly made of polyurethane. The diameter and durometer of the wheel affect the way the board rides. The diameter and durometer are a matter of personal preference and skating style.

Diameter is the size of the wheel when measured from top to bottom. All Skateboard wheels are measured in millimeters (mm). The smaller the number, the smaller the wheel. Smaller wheels are slower; bigger wheels are faster.

50-53mm Small, slower wheels; stable for trick riding and smaller riders skating street, skate parks, and bowls.
54-59mm Average wheel size for beginners and bigger riders skating street, skate parks, bowls, and vert ramps.
60mm + Specialty riders skating longboards, old-school boards, downhill, and dirt boards; made for speed and rougher surfaces.

What durometer skateboard wheels do I need?

Durometer measures the wheel’s hardness. Harder wheels are faster; softer wheels are slower but have better grip.

Skateboard wheel durometer is usually measured on a Durometer A Scale which goes from 1-100 to measure hardness. Some companies use the B Scale which measures 20 points lower, allowing the scale to be extended by 20 points for harder wheels. For instance, an 80b durometer is the same as 100a durometer. These skateboard wheels have a larger and more accurate range of hardness. The average wheel durometer is 99a.

78a-87a Soft wheels good for rough surfaces, longboards, or street boards that need lots of grip to easily roll over cracks and pebbles. Designed for smooth rides, cruising, longboards, hills, and rough surfaces.
88a-95a Slightly harder and faster with a little less grip, but the grip is still good. Good for street and rough surfaces.
96a-99a Nice speed and grip-- an all-around good wheel. Great for beginners skating street, skate parks, ramps, pools, and other smooth surfaces.
101a + Hardest and fastest wheel with the least grip. Ineffective on slick and rough surfaces. These are pro wheels.
83b-84b Wheels using the B scale are extremely hard, measuring 20 points lower than the the A Scale in order to allow the scale to extend another 20 points for harder wheels.
