## Who it’s for

- You skate fast marathons and road races on dry, hard asphalt.
- You do demanding endurance training and want as little rolling resistance as possible.
- You have skates for 90 mm wheels and want the hardest compound in the VooDoo series.

## When to choose something else

- You ride skate cross or skate on wet or uneven asphalt — XX-Firm is too hard for that. See other [90 mm wheels](https://bogdanca.pl/en/wheels-and-bearings/wheels-90mm) with a lower hardness.
- You are only just learning to skate fast — these are wheels for advanced skaters.

## Key features

- **XX-Firm hardness** — The highest hardness in the VooDoo series: the highest rolling speed and the lowest resistance on a hard, smooth surface.
- **MTech Soft Heart, Hard Body** — The soft 63A inner ring gives stability at high speeds and predictable handling in the corners, and the hard outer urethane gives speed.
- **Magic Urethane without pigments** — The compound provides energy return, low wear over long distances, and resistance to high temperature and abrasion.
- **Natural Turbo Hub core** — The reinforced hub combines stiffness with energy transfer, and one-cavity casting gives identical parameters in every wheel.

## Questions and answers

### What conditions are the VooDoo 90 mm XX-Firm wheels for?

For hard, dry and smooth surfaces: tracks, fast marathons and road races.

### How does XX-Firm differ from Firm and X-Firm?

### Are these wheels suitable for skate cross?

No. At this hardness, wheels from the lower part of the scale will work better.

### What is the Natural Turbo Hub?

A wheel core with greater stiffness and precision at a low weight, cast in a single mould.

### Can you match spacers to these wheels?

Yes, as part of the separate service “Wheel core measurement and spacer matching”, which you add to your order.
