Complete Your Setup
New wheels deserve fresh bearings. Spitfire makes three tiers:
- Spitfire Cheapshots Bearings (Good): Spitfire's base-level bearing, tested by the pro team, with removable black shields to keep the crud out.
- Spitfire Classics Bearings (Better): Superfast and durable, with heat-resistant chromium steel rings, removable nylon cages, and blue removable shields.
- Spitfire Burners Bearings (Best): Spitfire's high-performance pick, with polished honed races and high carbon chromium steel, packed in a reusable tin.
FAQ
Is 99A hard or soft?
Hard. 99A is the standard street and park hardness: fast, with a controllable slide.
What is the Radial shape good for?
Versatile, all-around riding. Spitfire describes it as a round-edge, medium-width riding surface that offers the versatility of the Classic shape in the width of a Conical.
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.
