You can use these bearings in any situation, Downhill, Freeride, Freestyle, Cruising, ... All the protective casing and the interior are made of chrome, this makes them much superior to common steel bearings, perfect to achieve high RPM and reduce the weight and temperature, while the steel prolongs its durability.
These longboard bearings have very low coefficient of friction. As thermal properties are better than common steel balls, which generate much more heat at high speeds.
