Seismic Speed Vent 85mm Longboard Wheels - 78a Mango Defcon

The Seismic Speed Vent 85mm wheels are a top choice for various skating styles, thanks to their innovative design. Seismic pioneered the tall and wide hub that sets these wheels apart, providing exceptional performance.

What Makes The Seismic Speed Vent The Best Wheel For YOU

• Speed Vent wheels offer the perfect balance of properties for top speed, down hills and max mileage on LDP treks.
• The huge 85mm diameter of the Seismic Speed Vent brings speed and momentum to beat the pack on the straights!
• The Speed Vents are surprisingly quick, smooth and agile handling for their size - even through hard corners.
• Edges and bearing offset designed for race-style grip; the hub is engineered for weight reduction and energy return. The Seismic Speed Vent Core is in a class by itself!

Despite their size, these wheels are lightweight and incredibly fast, making them one of the best options for skaters seeking speed. The 85mm diameter ensures minimal rolling resistance, allowing skaters to glide effortlessly over rough pavements. While they excel in long-distance and straight-road skating, their large size may cause some chattering during slides or downhill runs.
