FR Junk Freestyle MPC 80 mm X-Firm skate wheels are a set of 8 clear wheels with an elliptical profile, made in Rhode Island from natural pigment-free polyurethane. The harder outer layer provides abrasion resistance, the soft inner one resilience, and the iHub5 hub is integrated with the tyre. Intended for intermediate and advanced skaters in freestyle slalom, urban skating and freeride.

The wheels wear mainly on the inner edge. From time to time swap their positions and turn them round so that they wear evenly.
For freestyle slalom, dynamic urban skating and freeride. They work best on hard, even surfaces: asphalt, in a skatepark and in a hall.
Similar, but not identical. The manufacturer uses its own hardness scale, in which X-Firm corresponds to roughly 83–85A. It is a very hard compound, best on dry, hard surfaces.
Because the polyurethane is natural, without pigments. The absence of dyes is meant to give better slide, less wear and a longer life.
For optimal rolling, 10.00–10.10 mm spacers fit. In the shop we can measure the wheel cores and select spacers as part of the “Skate wheel core measurement and spacer selection” service.
Yes, if you have four-wheel inline skates. 8 pieces make a set for a pair – four wheels per skate.
