This is a special wheel developed for dirty snow conditions, which have small stones or sand that cause a very accelerated loss of edge; the imprint this wheel leaves on the edge is very similar to a micro serration clearly developed to obtain the correct final result for the athlete. The mixture used is of the same synthetic resin type as the other synthetic grinding wheels, in addition it contains a hardener which allows the grinding wheel to obtain a finer grain than itself.
