The Speedster is designed for rolling speed and minimal drag on hard-pack or paved terrain. The honeycomb center tread provides virtually zero rolling resistance and unbelievable tread life. This feature also gives you excellent traction in dry or wet conditions. Large diamond shaped side knobs provide the grip you need in corners, while the tread knobs get smaller towards the center for the ultimate speed and traction. And with its balloon-style structure, youâ€™ll feel like youâ€™re floating on air.
