Many new road bicycle buyers may come in with the notion that having a higher set of handlebars will equal more comfort. This is not always true, being that if your handlebars are too high it means that your weight will then be shifted back into the seat. Then, it will feel as if you’re riding with most of your body weight in the back, which will feel uncomfortable and decrease your ability to accelerate speed quickly in most cases.
The same thing can happen if your handlebars are too low, because your body may not lean into them correctly depending on how long or short your arms and legs are, or how wide or slim your body is overall. Even though you may be in that low, aerodynamic position as you pedal, you won’t feel comfortable during your ride if you are forcing yourself into it. This is why things such as your handlebars and seat should be tested out at your initial buying of the bike so that you don’t run into these aggravating small problems later.
