Formula Four Lock-In Full Wheels

Spitfire Formula Four Lock-In Full wheels are heavy-duty, asymmetrical skateboard wheels designed to give you a massive edge on grinds while maintaining high-speed stability. They feature a unique hybrid shape: a completely straight, square edge on the inside to lock into rails and ledges, paired with a rounded conical cut on the outside to shed unnecessary weight. This "Full" variant expands on the standard Lock-In profile by offering a much wider riding surface for all-terrain control.
