## Who it’s for

- You skate in the city or do fitness training on four-wheel skates with 80 mm wheels.
- You have working bearings and spacers in your old wheels and want to move them over to the new set.
- You want wheels that accelerate quickly after push-off and guide the skate calmly in corners.

## When to choose something else

- You do not have bearings to move over — buy them separately, see [skate bearings](https://bogdanca.pl/en/wheels-and-bearings/bearings).
- Your frame takes 76 mm at most — choose [Hydrogen Spectre 76 mm](https://bogdanca.pl/en/rollerblade-hydrogen-spectre-wheels-76-mm-85a-white-4-pcs.html).

## Key features

- **Premium-formula polyurethane** — Springy, flexible urethane withstands abrasion well and returns push-off energy.
- **Solid Core** — A strong core gives stability and precise handling, and the wheel holds a constant speed more easily.
- **Scooped Inner Core cut-outs** — Profiled cut-outs inside the core reduce the wheel’s weight, so you accelerate faster, and vibration from the surface is damped better.
- **Elliptical profile** — A narrower footprint makes it easier to lean the skate and gives confidence in corners.
- **Set of 4** — It fits one four-wheel skate; for a pair of skates you need two sets.

## Questions and answers

### Are bearings and spacers included?

No. The set is just 4 wheels. You move the bearings and spacers over from your old wheels or choose them separately.

### Are 4 wheels enough for a pair of skates?

No, if you have four-wheel skates. Four wheels fit one skate, so for a pair you need two sets.

### Will these wheels fit my skates?

Yes, if the frame of your skates takes 80 mm wheels. The easiest way to check is the print on your old wheels: if it says 80 mm, it is a direct replacement.

### How do they differ from the other colours of Hydrogen Spectre 80 mm?

In colour. The 80 mm diameter, 85A hardness and number of wheels are the same, so you can make up a pair from two sets in different colours.

### 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.
