Spitfire F4 Conical Full Wheels | 97D/56mm

Spitfire F4 Conical Full Wheels | 97D/56mm

A wide 56mm Conical Full in 97D for smooth roll on crusty ground.

This 56mm Conical Full runs Spitfire's 97D Formula Four, a little softer than the classic 99D. It suits skaters who ride rough parks, bowls and street spots and want a bigger wheel that stays planted and quiet.

Spitfire's Conical Full shape has a wide riding surface with cut-in sidewalls, so you get stability and grip without the extra weight. 97D adds a bit more grip and comfort on rough concrete, and Formula Four keeps it round, fast and smooth to slide.

About Spitfire

Spitfire Wheels started in San Francisco in 1987 and is still based there today, distributed through Deluxe alongside some of the city's best-known skate brands. The flame logo has been on the bottom of street, park and bowl setups ever since.

Today Spitfire is best known for Formula Four, its performance urethane built to resist flat spots, hold its shape and slide smoothly without sticking. It comes in a wide spread of shapes and hardnesses, from soft 80HD cruisers to hard 101D park wheels, so you can match the wheel to how and where you skate. Riders choose Spitfire because the wheels are consistent from set to set and simply last.

FAQs

What are the Spitfire F4 Conical Full 97D 56mm wheels best for?
Rough parks, transition and crusty street spots where a bigger, slightly softer wheel helps. The Conical Full is a wider version of Spitfire's Conical. The riding surface is wide for stability and grip, and the sidewalls are cut in to keep weight down, so it feels solid and controllable everywhere.

What does 97D mean?
Spitfire rates hardness on its own Duro scale, written D or DU, and doesn't publish a conversion. Retailers generally list it on the A scale, so 97D is usually listed as 97A, a step softer than the classic 99D. You get a touch more grip and a smoother, quieter ride on rough ground, while still keeping Formula Four's clean slide.

What size wheel should I get, and do I need risers?
56mm is a bigger wheel for parks, bowls and transition, or for rougher streets where you want more roll. On most standard and mid trucks you can run them without risers; on low trucks or with soft bushings, add a 1/8" riser to avoid wheel bite.

Do they come with bearings?
No. They come as a set of four wheels without bearings. Any standard 608 skate bearing fits, so you'll need a set of eight bearings, and spacers if your bearings don't have them built in.
