The hardness of our wheels is indicated using the SHORE A hardness scale. The higher the number, the harder the wheel compound.
Harder wheels typically* have better rolling capabilities and better wear resistance compared to softer compounds. The benefit of softer compounds is that they offer more grip and a smoother and more comfortable ride, especially on rough asphalt.
*“Harder wheels are always faster” is a widely spread myth and not 100% true. When skating on rougher surfaces, softer wheels cause fewer vibrations and that for offer a better roll. Yet, it’s true that in many or most cases a harder wheel still makes for a faster ride.
