An interesting concept which has amazing results! Instead of
the standard tube-style packing, this 'H' shaped packing
replacement forces the hop rubber into a more natural cup
around the BB.
So instead of the hop rubber just gripping the top edge of the
BB, the 'H' packing will grip a much larger surface area and
therefore offer more spin and finer adjustment.
Pressore specifico per distribuire in modo perfetto la pressione
sul gommino hop up ed ottimizzare al meglio l' effetto rotazione
sui pallini.
