Rollerblade's Hydrogen wheels are unsurpassed in terms of power transmission, rolling resistance and durability.
The wheel's core is designed so that it flexes optimally in relation to power transmission and together with the secret rubber mixture, a wheel is obtained that is state of the art on all parameters. This is the wheel for the demanding and uncompromising runner.
The wheel has the following properties:
- Diameter: 84mm
- Hardness: 85A
- Bearings and spacers not included
NOTE that the wheel in the picture is not an 84 mm wheel but the design is exactly the same.
