## Who it’s for

- You have speed or marathon skates on 4×110 mm frames and want to replace all eight wheels at once.
- You race marathons or train over long distances and need wheels that hold their direction steadily at high speed.
- You have your own bearings and spacers and want to move them over to the new set.

## When to choose something else

- You have 3×110 mm three-wheel skates — the [set of 6](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-110-mm-85a-white-lime-6-pcs.html) is enough for you.
- Your four-wheel frame takes 90 mm at most — see [Hydrogen 90 mm](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-90-mm-85a-white-lime-8-pcs.html).

## Key features

- **4×110 mm layout** — A longer wheelbase and a larger contact area than on a three-wheel frame: the skate is more stable at the highest speeds and holds a straight line more easily.
- **110 mm diameter** — A large wheel rolls longer after a single push-off and passes over bumps more easily than 80–90 mm wheels.
- **85A hardness** — A hard tread wears slowly and transfers push-off force well in a long marathon stride.
- **Set of 8** — Four wheels per skate, so you replace the whole set in one purchase and the wheels wear evenly from the start.

## Questions and answers

### Which frames is this set for?

4×110 mm four-wheel frames. Eight wheels means four per skate — the standard layout in marathons and classic speed skating.

### How does skating on 4×110 mm differ from a three-wheel layout?

Four wheels give a longer wheelbase and a larger contact area with the ground. The skate is more stable at high speed and holds a straight line more easily.

### Are bearings and spacers included?

No. The set is just 8 wheels. You buy bearings and spacers separately or move them over from your current wheels.

### Can I fit these wheels on three-wheel skates?

Yes, if the frame takes 110 mm, but you will be left with two spare wheels. For 3×110 mm skates there is a [set of 6](https://bogdanca.pl/en/rollerblade-hydrogen-wheels-110-mm-85a-white-lime-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.
