## Who it’s for

- You have Rollerblade Twister or Maxxum on 4×90 mm frames and want to go back to the factory wheels.
- You skate fast in the city, jump off kerbs and need stability on landing.
- You are moving from 80 mm to a 4×90 mm frame and are looking for wheels that damp cobbles and worse asphalt better.

## When to choose something else

- Your frame takes 80 or 84 mm at most — check the print on the frame and choose [Hydrogen 80 mm](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-80-mm-85a-white-lime-8-pcs.html) or [84 mm](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-84-mm-85a-white-lime-8-pcs.html).

## Key features

- **Twister and Maxxum factory specification** — Rollerblade fits the same urethane component to these skates on 4×90 mm frames, so after the replacement you go back to the factory setup.
- **4×90 mm layout** — Higher speed, easier acceleration and better vibration damping than on 80 mm wheels, with manoeuvrability retained.
- **Four points of support** — They give longitudinal stability on landings and at high speeds.
- **Premium high-rebound urethane, 85A** — A hard but springy American compound damps small vibrations on asphalt and cobblestones.
- **Set of 8** — Four wheels per skate — you replace the whole set on both skates at the same time.

## Questions and answers

### Do these wheels fit Rollerblade Twister and Maxxum?

Yes, the versions on 4×90 mm frames. It is the same wheel model that Rollerblade fits to them as standard.

### What does the 4×90 mm layout give me when skating in the city?

Higher speed, easier acceleration and better vibration damping than on 80 mm wheels. Four points of support also keep the skate stable on landings and at high speed.

### How does 85A hardness behave on uneven asphalt and cobbles?

Well. The Hydrogen compound is hard but springy, so it damps small vibrations and rolls smoothly.

### How do they differ from Hydrogen 90 mm / 85A without the white/lime label?

In colourway. The 90 mm diameter, 85A hardness and number of wheels are the same — see [Hydrogen 90 mm / 85A](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-90-mm-85a-8-pcs.html).
