Hello, I have taken many volkl handles completely to the hairpin area, the
yellow plastic pieces you see are just spacer blocks where the two hairpin
tubes come together ,then a graphite material is used to form the subhandle
to which the pallet is attached. I make a prostock type set up by adding silicon
or tungsten or lead the the hairpin or the subhandle areas. You do not want to do this unless you have some custom frame experience .
