In brief

Rollerblade Hydrogen 90 mm / 85A (8 pcs) is a set of eight wheels for fitness and recreational skates with room for 90 mm — four per skate. The 90 mm diameter combines speed with stability and manoeuvrability, and 85A hardness gives a durable tread and grip even on an uneven surface. Hydrogen polyurethane is abrasion-resistant.

Who it’s for

You do fitness skating at a brisk pace and have four-wheel skates with a frame for 90 mm.
You get around the city on skates and want wheels that wear slowly.
You are replacing a worn set and want all eight wheels from the same series.

When to choose something else

Your frame takes 84 mm at most — check the largest permitted diameter and choose Hydrogen 84 mm.

Key features

90 mm diameter: A balance between speed, stability and manoeuvrability — a size for energetic fitness skating.
85A hardness: The tread lasts a long time, keeps its grip and stays comfortable even on an uneven surface.
Hydrogen polyurethane and core: The compound is abrasion-resistant, and the precisely made core makes the wheel roll smoothly.
Set of 8: You replace all the wheels on four-wheel skates at the same time — four per skate.

Care and servicing

The wheels wear mainly on the inner edge. Every so often, swap their positions and flip them to the other side so that they wear evenly.

Questions and answers

Will these wheels fit my skates?

Yes, if you have four-wheel skates with room for 90 mm wheels — this applies to most fitness and recreational skates of this diameter. Check the largest permitted wheel size on the frame.

Are 8 wheels enough for a pair of skates?

Yes. Eight wheels is a full replacement on skates with four wheels under each foot.

How do they differ from Hydrogen 84 mm?

In diameter. A 90 mm wheel is faster and rolls better over bumps, but it requires a frame with room for this size; you can find the smaller one here: Hydrogen 84 mm / 85A.

How do they differ from the white/lime version?

In colourway. The 90 mm diameter, 85A hardness and number of wheels are the same — see Hydrogen 90 mm / 85A white/lime.

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.
