Who it’s for

You enter competitions and marathons, and the routes are sometimes slippery, patched or badly worn.
You race in sprints and care about grip when accelerating hard and in tight turns.
You have 3 × 125 mm skates and are replacing the whole set of wheels at once.

When to choose something else

You mostly skate on a dry, smooth track and count on maximum roll – choose Hydrogen Pro 125 mm X-Firm or XX-Firm.
Your frame takes smaller wheels – 125 mm needs a frame designed for that diameter, see frames.

Key features

Firm hardness: The softest variant in the series holds slippery, uneven and worn surfaces better, where harder wheels start to slide.
M-TECH Dual-Pour: The soft inner layer gives grip and control in turns, and the harder outer one adds speed and wear resistance.
Turbine Core with 9 spokes: Stabilises the wheel, absorbs vibration and transfers the force of your push efficiently – useful in a marathon and in competition.
125 mm diameter: A very large wheel rolls for a long time after each push and goes over bumps more gently.
Made in the USA: The mix of materials is designed for dynamic energy return and a long life.

6 Rollerblade Hydrogen Pro 125 mm Firm wheels

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 Firm differ from X-Firm and XX-Firm?

In hardness. Firm is the softest and gives the most grip on slippery, uneven or worn surfaces. X-Firm and XX-Firm are harder – they roll better on a dry, smooth track.

Are 6 wheels enough for a pair of skates?

Yes, for a pair of three-wheel 3 × 125 mm skates – three wheels per skate.

Are bearings and spacers included?

No. The set is 6 wheels only; you can swap the bearings and spacers over from your old wheels or buy them separately.

Will 125 mm wheels fit in my skates?

Only if the frame is designed for 125 mm wheels. Check the print on your current wheels or the largest diameter allowed for the frame; if in doubt, bring your skates to our shop in Poznań or Wrocław.

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.
