## Who it’s for

- You train for speed or race inline marathons and need wheels that hold the corners well.
- You skate on smooth city surfaces and want fast rolling without switching to the largest diameters.
- You ride skate cross — it is one of the uses of this version.

## When to choose something else

- You skate mainly on wet or very uneven asphalt — a hard wheel loses grip there. See other [90 mm wheels](https://bogdanca.pl/en/wheels-and-bearings/wheels-90mm) with a lower hardness.

## Key features

- **90 mm diameter** — An in-between diameter: faster than an 84 mm set, and lighter and more manoeuvrable than 100–110 mm wheels.
- **MTech Soft Heart, Hard Body** — The soft 63A inner ring gives flexibility in the bends, and the harder outer urethane gives a fast return of energy on the straights.
- **X-Firm hardness** — The intermediate hardness combines control in the corners with fast rolling on tracks and roads.
- **Magic Urethane without pigments** — The compound gives grip, low resistance and resistance to abrasion and temperature, and the lack of pigments is meant to ensure an even hardness around the whole circumference.
- **One-cavity casting** — Every wheel in the set has the same parameters and the same dynamic balance.
