NiNjA Ultra Speed Oil (USO) has the distinct advantage of super high rotational rates (optimum speed).
NiNjA USO is synthetically designed to handle both radial and lateral dynamic loading as well as high speed vibrations better than any other speed oil product available.
It resists thermal breakdown, resists spin out, and will not attract contaminants.
NiNjA USO is micro filtered in the factory specifically for use in skate bearings.
Less friction and higher rotation = maximum performance at greater speeds.
