i started looking for replacement mirrors because the one of the stockers would always let the wind adjust it at speed. i found a pair of the expensive napoleons on ebay for super cheap and figured i would try em out.
the view is more functional than stock- less me, more behind me.
the vibrations are way less than stock.
i think i have euro bars too- dont know, bought em off proteal a while ago, but with the pull back and the inch or so teal cut off each end they make the situation much more streamlined and i still get a virtually me free view of the road behind.
could not recommend them more highly.
