Made in Italy 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.
