Seismic Alpha wheels 75.5mm 76a Defcon

75.5mm x 62.5mm
Defcon Urethane
Offset core

A highly-optimized balance of properties for modern racing

Size and momentum to carry you past the competition in straightaways – yet agile enough for quick acceleration, fast edge-to-edge adjustments, and snappy technical pre-drifts. Welcome to a whole new realm of FAST!

Finely-calibrated width and supremely supported edges for smooth, predictable handling through even the hardest corners.

The very fastest urethane that the skateboard industry has ever seen, bar none.

Named after the Greek letter “alpha” (α), used in science to represent rotational acceleration.
