Spitfire Formula Four Tablets Skateboard Wheels 53mm - 101a Duro

Narrow - The least amount of traction intended for advanced, technical skateboarding.

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

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.

Tablet - An original Spitfire shape. It's lightweight, quick, and responsive. A straight cut profile, and a thin riding surface makes these wheels great for locked in grinds and controlled slides.

101a - Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.
