Handlebars are a crucial mountain bike cockpit component, as the bar has a major impact on how a bike rides and handles. The width of a bar, the amount of rise, and the amount of back sweep all have a big impact on mountain biking ride style and handling.
Handlebars are generally available in three different materials: aluminum, carbon, and titanium. Some of the best bars are made of carbon, which is very light and can help damp the vibrations coming from the trail. Titanium lasts a long time and also helps damp vibration, but it is much heavier than both carbon and aluminum. While aluminum is lighter than titanium, it is much stiffer and harsher than ti or carbon. However, aluminum is generally the most affordable handlebar material.
