Overview
For a board that needs fresh wheels, Spitfire offers the Formula Four in the Classic shape. The set holds four polyurethane wheels in green, at the 101a hardness named in the title.
Hardness and diameter are the two numbers that matter, and the listing gives the diameter two ways. The skill level is listed as intermediate, and bearings are not part of the set.
Who it's for
Intermediate skaters who want the Classic shape in a standard hardness are the target. Anyone who needs bearings in the same box, or confirmation of the diameter, should check first.
Pros and cons
- Set of four
- Diameter listed two ways
- No bearings included
Performance notes
Diameter and urethane hardness decide speed, grip and how the wheel handles rough ground. Replacing all four wheels refreshes a whole board, and the shape sets how the contact patch rolls.
