Handlebars that are too wide can make it difficult to maneuver the bike, while bars that are too narrow can cause discomfort on long rides. The best gravel bikes have handlebars that are roughly 44-46 centimeters wide. This provides a balance between control and comfort, and helps to reduce fatigue on longer rides. When choosing gravel bike handlebars, it is important to consider both your riding style and the type of terrain you'll be riding on. By selecting the right width for your handlebars, you can ensure a more enjoyable and efficient ride.
