DEVIL

The Devil wheels are designed for high-level roller skating, and to adapt your skating to many different surfaces, particularly very slippery ones, without compromising on speed and roll.

Given their characteristics, these wheels have been equipped with a rigid hub that allows them to roll extremely well, with incurring the typical flattening that is expected with very soft traditional wheels, or the slowdowns of polyurethane wheels.
The tread is produced by injection of a mix of thermoplastic polymer materials.
The rounded finish allows for use with little to no adjustment time.
It is possible to combine these wheels with the Professional wheels for a perfect balance between grip and smoothness.
Available in seven hardnesses (colors) and one diameter: 57mm.
Available in sets of 8 wheels (It is at the discretion of each reseller to sell units in smaller quantities).
NOTE: in the transition from Magnum/Giotto to Devil, it is a good practice to consider a lower hardness with respect to the previously used (ex: Magnum/Giotto 49 -> Devil 47)
It is advisable to periodically clean the wheels, taking care to:

remove the bearings
remove the dust with a rag
wash the wheels with water and a light, neutral soap
avoid harsh products such as alcohols, gasoline, etc.
