Hello since the 'head' of the mounting bolt on most daul pivot brakes is "blind" (for lack of a more tech term) it would be hard to switch it.
unless one is derperate for daul pivot (which I personally see no great benifit in) there are pleanty of good quality older brakes around.
ashon, what kind of bike do you have and what is the current brakes? OH btw welcome to forum
