In brief

Rollerblade Hydrogen Pro 110 mm X-Firm is a set of 8 wheels for speed skates, made in the USA. The two-layer M-TECH Dual-Pour construction combines softer polyurethane inside with harder polyurethane outside, and the turbine core with 9 spokes damps vibration at high speed. They work best on a dry, smooth surface: track, marathon, fast city skating. Bearings and spacers are not included in the set.

Who it’s for

You enter marathons or track races and need wheels that return the energy of your push well.
You skate fast around town on 4 × 110 mm skates and want to replace the whole set at once.
You train mainly on dry, even asphalt, but do not want wheels that lose grip straight away when the route gets worse.

When to choose something else

You often skate on slippery, uneven or worn asphalt – Firm hardness will give more grip, e.g. Hydrogen Pro 110 mm Firm.
You skate recreationally at a relaxed pace – in the skate wheels section you will find urban and fitness models.

Key features

X-Firm hardness: The middle hardness in the Hydrogen Pro series, between Firm and XX-Firm: fast rolling on dry, smooth asphalt and a margin of grip when conditions are worse.
Two-layer M-TECH Dual-Pour construction: The softer inner ring works under load and improves grip in turns, while the harder outer layer provides stiffness and speed.
Turbine core with 9 spokes: Limits vibration and stabilises the wheel, so it is easier to stay in control at high speed.
110 mm diameter: A large wheel rolls longer after a single push, which matters over a long distance and in a marathon.
Made in the USA: The polyurethane compound is aimed at high energy return and a long life, even with intensive training.

Care and servicing

The wheels wear unevenly, mainly on the inner edge. Every few training sessions swap their positions and turn them round so that the whole set wears evenly.

Questions and answers

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

In hardness. Firm is the softest variant, with the most grip on slippery and worn surfaces; X-Firm is for dry, smooth roads; XX-Firm is the hardest version, aimed at maximum roll on straights.

Are 8 wheels enough for a pair of skates?

Yes, for a pair of 4 × 110 mm skates – four wheels per skate. For three-wheel 3 × 110 mm skates you need 6 pieces.

Are bearings and spacers included?

No. The set is 8 wheels only; you can swap the bearings and spacers over from your old wheels or buy them separately.

Can I skate on them on wet asphalt?

Yes, but that is not their main job. X-Firm works best on a dry, smooth surface; if you often skate on slippery or damaged asphalt, choose Firm hardness.

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.
