## Who it’s for

- You commute by skates to work or classes and want a skate that rolls steadily on the straights and copes with small bumps.
- You skate on 80 mm wheels and are looking for more speed without switching to fitness skates.
- You train over long distances and need a boot with buckles that you tighten the same way every time.

## When to choose something else

- You want the greatest speed on three 110 mm wheels — see the [Lightning 110](https://bogdanca.pl/en/rollerblade-lightning-110-inline-skates-white-black.html).

## Key features

- **Four Hydrogen SE 90 mm / 85A wheels** — The Bullet Radius profile absorbs bumps and gives speed; compared with 80 mm wheels, the skate is more stable on the straights and copes better with small obstacles.
- **Extruded Alu frame for up to 90 mm** — A stiff frame with racing axles and lateral adjustment transfers push-off energy well.
- **Memory Buckle** — The top buckle and the 45° buckle remember their setting, so you fasten the skate with the same tension every time.
- **Ventilated hardboot shell** — A moulded shell with a V-cut holds the foot firmly, and the openings let heat out; the side slider is replaceable.
- **PSI liner with Shock Eraser** — An anatomical inner boot with full lacing; a damper under the heel absorbs vibration.
- **Footboard Sizer** — The pad reduces the inside of the boot by half a size, so one skate covers two neighbouring sizes.

## Choosing your size

Choose your size by foot length. Measure it in centimetres and compare it with the manufacturer's chart; for example, a foot of 25.6–26.5 cm corresponds to size CM 26.0 / 26.5 (EU 40.5 / 41), and a foot of 27.6–28.5 cm to size CM 28.0 / 28.5 (EU 43 / 44).

The Footboard Sizer pad reduces the shell by half a size, e.g. from EU 42 to 41.5. You can try the skates on in our shop in Poznań or Wrocław; when ordering with delivery, you have 14 days to withdraw from the contract.

## Questions and answers

### How do 4 × 90 mm wheels differ from 4 × 80 mm?

Larger wheels give higher speed, more stability on the straights and better handling of small obstacles. Switching from 80 mm to 4 × 90 mm makes sense when you want to skate faster and more smoothly on the straights.

### What is the Footboard Sizer for?

It reduces the inside of the shell by half a size, e.g. from EU 42 to 41.5. This way one skate covers two neighbouring sizes.

### Is the brake included?

Yes. The brake with a dedicated axle is in the box, together with an Allen key.

### Is the frame the same length in all sizes?

No. In sizes 35–39.5 the frame is 274 mm, and in sizes 40–48.5 it is 280 mm.

### What are Hydrogen SE wheels and SG9 bearings?

Hydrogen SE are 85A wheels with a Bullet Radius profile, which absorb bumps and give speed. SG9 are bearings with silicone grease and high rotational precision.
