Spitfire F4 Lock In Full Wheels 57mm 99a
SURFACE
Smooth – Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.
WHEEL PROFILE
Wide – More traction and stability at high speed so you’ll be less likely to slip out of your line.
KEY FEATURES
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.
WHEEL 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.
DUROMETER
99a – Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.
