Spitfire Formula Four Classic Spanky Happy Pro 52mm 99a

Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.

Medium - Your classic wheel shape, versatile all-around wheel for street/park skating.

Formula Four Urethane - Unmatched abrasion resistance for fewer flat spots. More controllable grip. Lasting speed no matter the terrain. Smooth anti-slick slide and a longer lasting size and shape.

Classic Shape - The original Spitfire wheel designed and shaped by the pros who ride them.

99a - Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.
