# Rollerblade Hydrogen wheels 125 mm / 85A (6 pcs)

Rollerblade Hydrogen 125 mm / 85A (6 pcs) is a set of six wheels from the Hydrogen series — three for each skate with a three-wheel frame. The 125 mm diameter requires a frame designed for such wheels, and 85A hardness means a hard, slow-wearing tread for asphalt. You can check the fit with your frame in our shop in Poznań or Wrocław.

## Who it’s for

- You have three-wheel skates with a frame for 125 mm wheels and want to replace a worn set at once.
- You want a large wheel that rolls for a long time after push-off, and you already have a frame prepared for this diameter.

## When to choose something else

- Your frame takes 110 mm at most — check the largest permitted diameter and see [110 mm wheels](https://bogdanca.pl/en/wheels-and-bearings/wheels-110mm).

## Key features

- **125 mm diameter** — A large wheel rolls for a long time after a single push-off; it also raises the skate, so it needs a frame for this diameter and a confident ankle.
- **85A hardness** — A hard tread wears slowly and rolls lightly on asphalt.
- **Set of 6** — Enough to replace all the wheels on a pair of three-wheel skates — three per skate.
