## Who it’s for

- You skate fitness and feel that the factory wheels slow you down on longer routes.
- Your route runs over rough asphalt and you want wheels that damp vibration.
- You have four-wheel skates with a frame for 84 mm or more and are replacing the whole set.

## When to choose something else

- The frame of your skates is made for 80 mm at most — these wheels will not fit; choose [Hydrogen 80 mm](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-80-mm-85a-white-lime-8-pcs.html).

## Key features

- **Lower rolling resistance** — The Premium compound rolls more lightly than budget factory wheels, so you keep the same speed with less effort.
- **Springy polyurethane** — It returns energy on push-off and damps small vibrations on rough asphalt.
- **85A hardness** — The tread is wear-resistant, so the set lasts longer than budget factory wheels.
- **Set of 8** — It covers a full replacement on classic four-wheel skates — four wheels per skate.
