Spitfire Formula Four Conical Skateboard Wheels - white/green (101d)
The conical shape always better lock in for tricks than the classic shape. Being that they are thinner you have axel for ledge and rail tricks. It’s always fun to do power slide with these!

Simply Great

Spitfire Formula Four Conical Skateboard Wheels
Picked these up at my local but thought I'd review them here. Compared to my STF V1s these are just better for my skating. I have to skate pretty gnarly ground most of the time and my STFs (also 54mm) were just rattling like crazy under my feet. So I decided to pick these up in 99 and they ride so much nicer over the ground. Still hard but more comfortable while still having a slide that I like better than the Bones. I like how the wheel is square, but still maintained a slim(er) profile so it works well for more technical trucks even though it's a 54. If you skate then these are the wheels. Straight up

Spitfire Formula Four Conical Skateboard Wheels - razzle mash-up (99d)
Feel in love with the conical shape and the 99 dura feels better on bumpy roads. Nice and smooth in parks.

Grew up skating the classic spitfire shape but ended up liking this conical shape even better. The formula four 99D is a perfect wheel for both street and park. Highly recommended

I have been writing this will for the last two set ups and I like them so much I don’t want to try anything else! I hope that they are in stock every time I need new wheels.

how well do these slide

These have a 101d hardness, so that means they are going to be real hard and slide very well.
