## Who it’s for

- You race marathons and long-distance races on asphalt and want wheels that hold their speed with low rolling resistance.
- You do speed training and intensive sessions, and expect low energy loss on every rebound.
- You have skates with a frame for 125 mm wheels and are replacing a worn set with the same size.

## When to choose something else

- You race on a track — there the largest permitted diameter is 110 mm. See [Black Magic 110 mm X-Firm](https://bogdanca.pl/en/mpc-black-magic-wheels-110-mm-x-firm-black-8-pcs.html).
- You mostly skate in the rain — for wet routes there are [Storm Surge 125 mm XGrip](https://bogdanca.pl/en/mpc-storm-surge-rain-wheels-125-mm-xgrip-blue-clear-6-pcs.html).

## Key features

- **125 mm diameter** — A large wheel reaches a high speed with low rolling resistance, which matters most over long distances.
- **Dual Density technology** — The outer layer of polyurethane takes care of grip, even on wet asphalt, while the inner one dampens vibration and improves comfort.
- **X-Firm hardness** — The stiff compound loses little on rebound, so it is easier to keep up the pace without excessive effort.
- **Ultra High-Rebound polyurethane** — Springy and abrasion-resistant, so the wheels keep their properties for a long time in intensive skating.
- **Light composite core** — It combines low weight with strength and keeps the wheel stable at high speeds.

## Questions and answers

### Is a set of 8 wheels enough for a pair of skates?

Yes, and with three-wheel skates even with a spare: 3 × 125 mm frames need 6 wheels, so two are left over for replacement.

### Will 125 mm wheels fit my skates?

Only if the frame allows such a diameter. Check the largest wheels for your frame, and if in doubt, come with your skates to our shop in Poznań or Wrocław.

### Can I skate on them on a track?

No — on tracks the largest permitted diameter is 110 mm. 125 mm wheels are for asphalt: marathons, road races and training.

### How does X-Firm differ from XX-Firm?

X-Firm is one step less hard. It gives a little more grip, while the [XX-Firm version](https://bogdanca.pl/en/mpc-black-magic-wheels-125-mm-xx-firm-black-8-pcs.html) gives lower energy loss on a very smooth surface.

### How much does one wheel weigh?

About 180 g.
