4th new concept "roller suction effect" (roller skating)

the "roller suction effect" is the 4th new concept introduced, as intended & written (2/7/13)
(r.s.e. - conceptual approach, through cross industry knowledge)

applicability: spoke roller skates - spokes circumferentially disposed like fan blades.
                     the above mentioned example has been chosen, for it is intuitive;
                     for other spoke roller types, aerodynamic - in the spin :) - testing advised.

advice beforehand: when skating on this type - always avoid too dusty or too wet tracks.   

for this type of rollers, only heavy duty bearings would be a good option.
please check this out with your bearings' supplier.
