Devil is Roll-Line's freestyle wheel (57 mm) designed for high- and competition-level roller skating. Devil is available in seven (7) hardnesses made to adapt your skating on many different surfaces, particularly very slippery ones, without compromising on speed and roll. When used with Roll-Line artistic frames, use 7 mm bearings (not included).

ADJUSTMENT PERIOD & COMPATIBILITY
The rounded finish allows for use in competitions with a minimal adjustment time. 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. When transitioning from Giotto to Devil, it is a good practice to consider a lower hardness with respect to the previously used—for example: if you previously used Giotto 49, try Devil 47.
