Road Handlebars come in a wide range of shapes and sizes to suit everybody; bar width, reach (the amount the bar projects forward to where the levers mount) and drop (the amount the bar drops from the tops to the bottoms) are all choices dependant on rider preference. Many racers choose narrower bars to reduce aerodynamic drag. Road bar shape has also been broadly categorised into compact, traditional and ergonomic styles.
