I’m a big fan of swept back handlebars which are very out of fashion in the US for some reason. Everyone has handlebars like they’re trying to win the Tour de France but unless you are the type to time yourself and beat some pace does it really make sense to trade comfort away to gain a small efficiency advantage? I don’t think so. If you bike leisurely or as a commuter, look into handlebars that allow a more comfortable upright posture.
