Handlebars, Bars, Steering wings. Call them what you like we all need them.
Personally I always find changing bars to be a bit of an ordeal. Not just because I have to wrestle the grips on and not because I have to switch the brake levers, and the cables are inevitably no longer the ideal length. Simply because it changes the feel of the bike so much and I find it hard to adjust. When I finally decided to cut my bars down to a more modern narrow width about 2 years ago it took me the longest time to get fully used to it.
