The BIG PROBLEM with drilling holes in an aluminium dropbar for brake cables is that you introduce to very large stress risers of which the one at the brake lever is most likely to cuase the handlebar to snap. The hole under the handlebar at the stem need to be in a strongly reinforced area and they must be oval to allow the cable housing to exit. There again a high risk stress riser is created. A snapped handlebar in traffic or at speed is no jopking matter and usually results in a crash.
DON'T DRILL HOLES In ALUMINIUM DROPBARS!
