FAQ

Is 99A hard or soft?

Hard. 99A is the standard street and park hardness: fast, with a controllable slide.

What is the Conical Full shape good for?

Stability and locking into grinds. Spitfire describes it as a wider version of the Conical shape, with a wide riding surface and cut-in sidewalls to decrease weight: a solid, controllable shape for all terrain.

What size wheels should I get?

Smaller wheels (50 to 52mm) are light and technical, 53 to 54mm is the street and park go-to, and 55mm and up adds speed for transition and rough ground. See our skateboard wheels guide for more.
