Spitfire Formula Four Lock Ins for an Asymmetrical Edge
Skaters asking what makes the Spitfire Formula Four Lock Ins different from a standard round wheel will find the answer in the shape itself. This is a 99 duro wheel with an asymmetrical design, pairing a conical cut profile on one side against a straight edge on the other, built to lock on and hold a line with confidence.
Formula Four Compound and Asymmetrical Shape
The Lock Ins are built from Spitfire's 100% true performance urethane in a 99 duro, delivering more speed and control on all surfaces. The compound is engineered for unmatched flatspot resistance, a smooth anti stick slide, and a high rebound so the wheel keeps its roll and shape ride after ride.
Who Rides an Asymmetrical Wheel
- Skaters who want a wheel shape built specifically around lock in feel rather than a general purpose round profile
- Riders chasing more speed and control across varied surfaces, from smooth park concrete to rougher street spots
- Skaters who put wheels through heavy slides and want strong flatspot resistance backing them up
Because the conical cut side and straight edge side behave differently under your feet, riders often mount these when they specifically want that lock in sensation rather than a symmetrical Classic shape wheel.
Mounting and Care
Mount the wheels on your trucks with bearings and speed rings seated so they spin cleanly without wobble, and pay attention to wheel orientation given the asymmetrical conical and straight edge design. The 99 duro compound is formulated for a high rebound ride with strong flatspot resistance, so rotate wheels periodically as they wear to keep that performance even across the set. Rinse away sand or salt residue after beach area sessions to protect the bearings.
