Spitfire Formula Four Classic Wheels 97D

OVERVIEW

Spitfire F4 Classic 56mm 97a Skateboard Wheels are proven and tested by Spitfire Team riders, the perfect all around park size for hitting all the big features in the skate park

Wheel Size -  The 56mm size will give you consistent speed for faster street skating while also maintaining a solid roll on the flat and better momentum on medium to large transition and ramps. 56mm is really the perfect size if you want to go big but not too big. 

Wheel Shape / Profile: Classic - Spitfire claim this is the #1 shape in skateboarding world wide. And it probably is. This shape first emerged in the early 90’s and has been a popular go-to ever since.  It features a large radius from the bearing seat which produces a fairly narrow contact patch. It is the great all rounder.

Urethane - Formula Four 97A: Spitfire released their new Formula Four wheels a few years ago now. The latest formula was designed for more control when skating rougher DIY spots and tricky street terrain. This means a smoother roll. 97A is considered a softer wheel in the modern skateboarding scene. They are still very hard but with the edge taken off. The 97A formula will provide a little more grip on super smooth surfaces and is a little more forgiving to ride on rougher surfaces.
