Spitfire F4 93 Duros Classic. The Softest F4. Still Fast.

The Spitfire F4 93 Duro Classic is the most forgiving wheel in the F4 lineup — and that's not a knock on it. At 93 duro, this wheel absorbs rough pavement better than the 99 or 97, rolls more smoothly over cracks and debris, and gives you a noticeably more planted, comfortable ride without sacrificing the speed and consistency that makes the F4 formula worth running in the first place. Available in 53mm, 54mm, and 56mm, the Classic shape is a round-profile wheel that's been in Spitfire's lineup for decades because it works across terrain types: street, transition, rougher outdoor spots, or anywhere the ground isn't cooperating. If you've been running 99s and finding them too harsh on your local spots, the 93 Classic is the answer.

Why We Carry Spitfire

Spitfire has been the benchmark for street skating urethane since 1987 — distributed by Deluxe, ridden by the best skaters in the world, and constantly refining their formula without abandoning what made them essential. The F4 line covers every skating style through thoughtful duro and shape variations, and the 93 Classic is one of the most practical options for real-world skating conditions. We carry Spitfire at 7B because when it comes to wheels, this is the standard everything else gets measured against.
