Seismic Alpha 80.5 mm wheels are made for going fast. Released as a downhill wheel now modified to serve as ultimate Long Distance wheel. The wheel has a high momentum for which results in optimum push and pumping speeds and are made of their fastest urethane.The s-shaped edge profile of the wheel supports the lip which results in ultimate edge to edge grip and the wheels actually have concave.
