The Storm S1 is a flow-formed, lightweight wheel manufactured by Advanti Racing. This wheel is constructed using the toughest aluminum alloy and utilizes the latest flow-forming technology to apply pressure on the inner wheel after casting. This process strengthens the wheel, limits the weight, and provides greater shock resistance. The Storm S1 features slender 10 spokes with deep center hub set in a concave rim. This awesome wheel comes in titanium mirror finish and available in 15-inch rim diameter.
