## Who it’s for

- You skate skate cross and need wheels that accelerate quickly and hold their line in tight turns.
- You enter marathons or race on the track on a dry surface and are looking for the middle hardness from the VooDoo series.
- You are replacing the set on four-wheel inline skates with a frame for 100 mm wheels.

## When to choose something else

- You race in the rain or on a wet route – X-Firm is for dry surfaces. For wet, take the [Storm Surge 100 mm XGrip](https://bogdanca.pl/en/mpc-storm-surge-rain-wheels-100-mm-xgrip-blue-clear-8-pcs.html).
- You mainly skate long straights and top speed matters – a higher one is reached by the [110 mm X-Firm version](https://bogdanca.pl/en/mpc-junk-voodoo-wheels-110-mm-x-firm-natural-8-pcs.html), provided your frame takes it.

## Key features

- **Two-layer MTech construction** — The soft inner ring gives grip in turns, and the hard outer urethane holds speed on straights.
- **Pigment-free Magic Urethane** — A resilient, durable compound that keeps its properties even after hundreds of kilometres of skating.
- **X-Firm hardness** — Works best on dry, smooth tracks and roads – there it gives speed without loss of control.
- **100 mm diameter** — Accelerates faster and handles more confidently in tight turns than 110 mm, which is why it is one of the most commonly chosen sizes in skate cross.
