## Who it’s for

- The factory wheels on your skates are worn down or coned and you want to replace the whole set at once.
- You skate around the city, freeskate or slalom and are looking for a hardness that grips on asphalt and doesn't wear quickly.
- You have four-wheel skates with 80 mm wheels and want to move your bearings into new wheels.

## When to choose something else

- Your frame takes 76 mm at most (some kids' and recreational skates) — check the print on your old wheels and choose [76 mm wheels](https://bogdanca.pl/en/wheels-and-bearings/wheels-76mm).

## Key features

- **High Rebound polyurethane** — The resilient compound returns the energy of your push, so the wheel holds its speed for longer while wearing slowly.
- **85A hardness** — A versatile hardness for asphalt and paving: it gives grip in corners and reasonable tread life.
- **Rounded urban profile** — It gives stability on the straight and lets you lean the skate confidently into a corner, even on smooth urban surfaces.
- **Reinforced core** — It withstands side loads and hard landings after jumps.
- **Centred bearing seats** — The bearings sit on the axis, so the wheel turns evenly, without wobble.
- **Bogdanca logo version** — It differs from standard Hydrogen wheels only in the print; the polyurethane compound is the same.

## Questions and answers

### Are 8 wheels enough for a pair of skates?

Yes. 8 pieces is a set for a pair of four-wheel skates — four wheels per skate.

### Are bearings and spacers included?

No. The set is just 8 wheels. You move the bearings and spacers over from your old wheels or choose them separately.

### Will these wheels fit my skates?

Yes, if you have four-wheel skates whose frame takes 80 mm wheels. If your old wheels are printed 80 mm, the swap is direct; with smaller ones, first check the largest diameter allowed for your frame.

### How do they differ from regular Hydrogen wheels?

Only in the print. It is the same polyurethane compound as in standard Hydrogen wheels, in a version with the Bogdanca logo.

### Can you match spacers to these wheels?

Yes, as part of a separate service, “Measuring wheel cores and matching spacers”. Measuring with spacers for 8 wheels costs PLN 90.
