Spitfire Formula Four Radial Full 56mm 93a
This Radial Full wheel keeps Spitfire's smooth, rounded edge profile, molded in Formula Four urethane — the formula Spitfire rolled out in 2013 for better flatspot resistance and longer-lasting grip, part of the legacy Jim Thiebaud built when he founded the company in San Francisco back in 1987. This pair measures 56mm at a softer 93a durometer, built for a smoother, more forgiving ride.
