Is it safe to drill cable routing holes into aluminum handlebars?
Hello all, I’m wondering whether it’s generally considered safe to drill holes (well sanded-off, of course) for cable housing through aluminum drop bars. I’d like to be able to route the cables from my bar end shifters—and maybe also my brake cables—through the bars so that my grip on the bars (as well as the look) is cleaner. It’s for a touring setup with disc brakes and with all the time my hands will spend on the bars, I’d love to have the feel be as comfortable as possible. If it’s safe to drill cable housing-sized holes into Salsa Cowchipper bars without compromising their structural integrity (or my shifting/braking/moral integrity), I’d be into it.
Thanks as ever for your help.
