Which side, left or right, is your front brake lever?
Which brake is your left brake lever?
Votes are public.
Turns out your answer likely depends on where in the world you are and possibly your dominant hand or personal preference.
If you're like a lot of people, you get a bike built by a bike shop and ride it that way. How they set it up appears to be consistent with which side of road your country drives on. It seems if you drive on the left side (like in the U.K. or Australia), the front brake is on the right hand of the handlebars, and if you drive on the right side (like in the U.S.), the front brake is on the left hand side.
I've seen some lefties swap positions, as have some people who just like it the other way. Maybe they grew up in a different country that drove on the other side of the road?
