The Spitfire Formula Four Durao Lock-Ins 54mm 99a is a pro model designed for precision control and grind consistency, built with Spitfire’s industry-leading Formula Four urethane. It delivers fast roll speed, smooth anti-stick slides, and long-lasting durability with strong resistance to flatspots, making it a reliable choice for both street and park skating (Zumiez).
The Lock-In shape features an asymmetrical design with a straight edge “lock-in” cut on one side and a rounded sidewall on the other. This creates maximum control on grinds while maintaining smooth slide release and versatility.
The 54mm size offers a strong balance of acceleration and speed, making it ideal for technical street skating while still providing enough size for stability on landings and park terrain.
99a durometer wheels are built for speed and lasting control across all surfaces. They offer a balanced mix of grip and slide, making them one of the most versatile and widely used durometers for both street and park skating.
