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)

Roll-Line does not sell directly to the public; to complete your purchase, please refer to an official reseller.

Each wheel hardness has been designed to adapt to a type of surface based on smoothness or roughness.
In general:

  • The softer the wheel (or the lower the “Shore” hardness number), the greater the grip and the slightly lower the smoothness.
  • The harder the wheel, (or the greater the “Shore” hardness number), the greater the smoothness and slightly less grip.

 

The following table shows the type of surface suggested for each wheel hardness.

Each color corresponds to a specific hardness (as shown in the table): 36 cream, 39 water green, 42 light blue, 45 pink, 47 light blue, 49 gray, 53 beige.
NOTE: when switching between Magnum/Giotto and Devil it is good practice to consider a lower hardness than the one used previously (e.g.: Magnum/Giotto 49 → Devil 47).

NOTICE:Factors such as humidity, dust, etc., can negatively influence the grip of the wheels on the skating surface.
For this reason it is preferable to have a variety of different types of wheels depending on where the training and competitions take place.
Changing the wheels does not require an adjustment period, but it is necessary to ensure that the wheels have a similar state of wear with respect to one another when equipped. To determine how to mix different types of wheels, please see the appropriate guide.

For more info on how to change wheels, please watch the video tutorial.

It is advised to verify the condition of your equipment at every use.

In particular, it is advised to check:

  • the state of wear of the wheels
  • the secure closure of the lock nuts on the wheels
  • the proper roll of the bearings

 

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.

It is recommended to substitute the wheels in a timely manner, to guarantee the optimal performance of the equipment.
Substitute the wheels once the edges are rounded to a cone-like shape, as indicated in the following graphic:
