The Top Speed Black 10 is made harder than the competitors yellow warm weather wax. With TS10B having adjusted hardness properties, the wax more excels in terms of durability when the snow is dirty. The black solid lubricant additive reduces the friction in dirty snow. TS10B works excellently in artificial snow as well as natural transformed older snow. TS10B can be used as a stand alone race wax, but is often used as a base for liquids or wool-applied top coats.
