Offering the best of both worlds, Spitfire introduces the Lock In Full-shaped skateboard wheels in a 54mm diameter with white 99a durometer flatspot-resistant Formula Four urethane. Adorned with classic branding and a spiral design on the sidewalls, the innovative wheels feature a special asymmetrical shape that utilizes the straight edge interior sidewalls from the acclaimed "Lock-In" shape while the exterior sidewall uses a rounder conical-shaped sidewall to handle rougher terrain easily.
