The Hydrogen Pro incorporates a multi-layer technology, Mtech®, which is comprised of two layers of urethane to provide the ultimate footprint for grip, rebound for speed/energy return, roll, and wear. This combined with the core makes it the most responsive wheel you can put on your skates.
Hydrogen Pro 90MM XX-Firm wheels are designed for marathons and open road races by providing optimal performance. Made in the USA with an exclusive dual-pour urethane formula, the outer ring enhances wear while the inner ring improves mechanical grip.

Their elite performance provided advanced speed with excellent wear and efficiency, these wheels can be skated in all conditions and supply the most roll of all the hardnesses.
The inner ring is softer for flex and the outer ring is firmer for speed. The turbine core helps keep the straight-line speed with vibration absorption and control.
