Spitfire F4 Lock In Full Wheels 57mm 99a

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

Wide - More traction and stability at high speed so you'll be less likely to slip out of your line.

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.

Lock In Full Shape - A wider version of the Lock-In shape. Keeping the asymmetrical shape and design while featuring a conically cut outer wall and a straight edge "lock-in" cut on the inside wall.

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