example1:
from drag bar to an ape hanger

- i would assume, depending on the length of the cables etc, you would need to re wire to accomodate the new handle bar (ie: would need longer cables)

example2
from ape to drag (let's say mini ape 12")

- would the cables need to be shortened? since the long cable can accomodate the shorter drag bar, how would this affect the functionality of the brake/clutch levers if the same cable length is used?!

how much length difference would it have to be for the cables to be adjusted accordingly?! (ie: if you only use a riser and raised it by an inch. cable wise it may not have any effects).

is there a suggested length/tension/slack for the cables with respect to handle bars?! i hope i made sense here thanks.
