Conical Shape

A true performance conical shape – hand cut for quick response and less weight. Ideal for skaters who prioritize quick response and lightweight performance, particularly for pool and transition skating.

Spitfire Duro 101The Duro 101 by Spitfire is harder of the two durometers, they will be faster in a skatepark than the 99Duro wheels, but are also more slippery. They will last longer because of a harder Durometer but not be as smooth in the streets as a 99D.

Formula Four UrethaneUnmatched abrasion resistance (no flat spots), more controllable grip, lasting speed everywhere, smooth anti-stick slide, longer lasting (holds size and shape longer).
