## Who it’s for

- You skate marathons or long endurance training sessions and want a large diameter that holds speed for a long time.
- You have 3×125 mm three-wheel skates and are replacing a worn set.
- You have well-developed technique and stable ankles — a skate set high off the ground is no problem for you.

## When to choose something else

- You are still building your technique or your ankles collapse inwards — the lower and more manoeuvrable [Hydrogen 110 mm](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-110-mm-85a-white-lime-6-pcs.html) will suit you better.
- Your frame does not take 125 mm — check the largest permitted diameter before ordering.

## Key features

- **125 mm diameter** — A large wheel holds its speed over a distance; it also raises the skate’s suspension point, so it needs stable ankles.
- **Scooped Core** — The multi-spoke black core stiffens the wheel, so the polyurethane does not flex at high speed or in a deep corner, and the push-off force goes into the surface.
- **Premium polyurethane from the USA** — The same compound as in earlier Hydrogen wheels — the new graphics do not change the springiness, durability or grip.
- **85A hardness** — A hard tread wears slowly and rolls lightly on asphalt.
- **Set of 6** — Three wheels per skate, i.e. a full replacement on three-wheel frames — the standard layout for a 125 mm diameter.

## Questions and answers

### Who are 125 mm wheels for?

For skaters with well-developed technique and stable ankles who skate marathons, long training sessions or fast around the city. A skate on 125 mm wheels sits higher than on smaller ones.

### How many wheels are in the set?

6 — three per skate, i.e. a set for a pair of skates with three-wheel frames. Bearings and spacers are not included.

### What does the Scooped Core give me?

Stiffness. The multi-spoke core stabilises the wheel at high speed and in deep corners, so the polyurethane does not flex and the push-off does not lose its force.

### Do the new graphics mean a different compound from earlier Hydrogen wheels?

No. It is the same Premium polyurethane formula from the US factory; only the look has changed. The same size in the other version: [Hydrogen 125 mm / 85A](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-125-mm-85a-6-pcs.html).

### Can I return the wheels?

Yes, you have 14 days to withdraw from the contract (return) without giving a reason. The buyer covers the return shipping.
