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.
