Spitfire Formula Four Classic blue 56mm 99a
This Classic wheel comes in Spitfire's rounded, do-everything shape — the same profile that's defined the brand since Jim Thiebaud launched it in San Francisco in 1987 under Fausto Vitello and Brian Ware's Deluxe Distribution. It's cast in Formula Four urethane, the formula Spitfire introduced in 2013 for better flatspot resistance and grip, finished in blue at 56mm, 99a durometer.
