## Who it’s for

- You skate marathons, track races or long endurance training sessions on a smooth, dry surface.
- You have many kilometres behind you on speed skating wheels and want the lowest rolling resistance the VooDoo series offers.
- You are replacing a set on speed skates that take 100 mm wheels.

## When to choose something else

- You skate skate cross or on uneven and wet surfaces – XX-Firm is too hard for that. See other [100 mm wheels](https://bogdanca.pl/en/wheels-and-bearings/wheels-100mm) of lower hardness.

## Key features

- **MTech Soft Heart, Hard Body** — The soft 63A inner ring damps vibration and stabilises the wheel in turns, and the hard outer urethane gives speed and wear resistance.
- **XX-Firm hardness** — The hardest VooDoo variant gives the lowest rolling resistance and good energy transfer on smooth, dry asphalt.
- **Pigment-free Magic Urethane** — The compound is meant to give quick acceleration, a long life and temperature resistance.
- **Natural Turbo Hub core** — A redesigned, stiffer hub transfers the energy of your push better. Each is cast in a single mould (one-cavity), so the wheel geometry is repeatable.

## Questions and answers

### What surfaces are the VooDoo 100 mm XX-Firm wheels for?

Hard, dry and smooth: tracks, roads and marathon routes.

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

In hardness. Firm is 82–84A (more grip, wet or uneven routes), X-Firm 84–86A (all-round, dry surfaces), XX-Firm 86–88A (top speed and lowest resistance).

### Are these wheels suitable for skate cross?

No. They are too hard: they are optimised for smooth tracks and long distances.

### What does MTech technology give?

It combines a soft inner ring with hard outer urethane: grip and control in turns and better use of energy on the straight.

### Can you select spacers for these wheels?

Yes, as a separate service, “Wheel core measurement and spacer selection”, which you add to your order.
