Rollerblade has been long known for making excellent skaters, but for quite a while, their wheels weren’t exactly up there when it comes to quality. Things have changes some time ago, when the company has introduced new Hydrogen wheels to the market. Nowadays, they are one of the best wheels on the market for freeskating, speed and even aggressive. Hydrogen and Hydrogen Pro are made in the USA, in fact in the same factory as legendary Matter and Undercover wheels. Not surprising then, that their urethane is excellent (although there’s a little bit more emphasis put on grip than in case of two ther brands). Hydrogens are durable, have slow and even wear, come with strong cores and super high rebound, which makes them really fast. They are true premium product. Hydrogen wheels in size can be compared to one of the best selling Matter wheels - Image. These are very versatile wheels, which will feel right at home in urban skating, wizard/flowskating and even in speedskating, as a solid mid-tier offering. They do lack the so called rebound strip (just like Images), but high quality urethane blend makes them really fast even without it.
