Spitfire Formula Four Classic 99A Skateboard Wheels.
These Formula Four wheels were designed in Spitfire labs and tested by Spitfire Team riders. Formula Four Performance Urethane lasted longer, withstood more abuse and performed superior to other skateboard wheels.
These sets of Formula Four Spitfire Wheels are in the Classic Shape for a slim riding surface for more speed and control.
Formula Four 99A Duromter Wheels Feature:
- Urethane formula for more speed and control on all surfaces
- Unmatched flatspot resistance
- Smooth anti-stick slide
- High rebound compound
- 100% True Performance Urethane
Formula Four Performance Urethane is unlike any other. Both in the streets and under high-speed stress tests in the Spitfire lab, Formula Four Wheels retained more material, coned less and kept their original shapes and sizes longer than any other wheel tested.
Formula Four Urethane is made using a 100% pure urethane compound. On the hills, in the streets & parks, and in forced flat spot testing in our lab, Formula Four wheels out-performed and resisted flat spots longer with less wear than all other wheels tested.
Formula Four's exclusive combination of High Rebound and Hard Duro produces a faster wheel everywhere that won't mush out over time. Higher rebound for faster speeds over rough and smooth surfaces.
Formula Four's exclusive anti-stick slide gives a fast/consistent, smooth slide all the way through. Slide with confidence start to finish knowing your wheels won't skip or catch mid-slide. Formula Four gives you the highest level of control and consistent grip you can count on.
These Spitfire Formula Four Skateboard Wheels have a 99a durometer hardness, which gives a skater more speed and control on all surfaces. This is a great all-around wheel for skating street, skate parks, ramps, pools or other smooth surfaces.
Sold in sets of 4 for a full skateboard. To attach these wheels to a set of trucks, you will need a set of 8 bearings (available separately from ChutingStar-Skate).
Available from ChutingStar-Skate in 50mm, 51mm and 52mm diameters. The 50-52mm sizes are smaller, lighter wheels most commonly used either for stable trick skating, advanced pro riders or smaller/younger skaters for street, skate parks and bowls. The 53-56mm wheels are the more common wheel size for beginners or bigger riders skating street, skate parks, bowls and vert ramps. Wheels 56mm and above are more common for skate filmers.
