Alpha super light magnesium rims are the best in the business. Straighter, stronger, and with a perfect fit on the axle. Strong threads that won't strip easily...you don't need a flat spot on your axle with Alpha rims or tires. Our rims are so good that other tire manufacturers buy them from us! Rims pictured from left to right. Big Hub, Small Hub, Big Full Hub. (Sold in pairs)
