The handlebars on a downhill mountain bike (DH) are a crucial component that greatly influences the rider's control, stability and comfort when riding downhill, a discipline that emphasizes speed and descent on terrain extremely technical. Here is a description of its function, its characteristics and the associated standards:
Function :
1. Directional control:
The handlebars allow the rider to steer the bicycle by transferring their steering movements to the front wheels.
2. Stability and balance:
A well-designed handlebar contributes to the stability and balance of the bike by providing a comfortable and ergonomic riding position, even in the most extreme downhill conditions.
3. Order support:
The handlebars are equipped with grips (handles) for a comfortable and secure grip, as well as locations for brake levers, shift controls, suspension controls and other accessories.
Features :
1. Width:
Downhill mountain bike handlebars are generally wider than those of other disciplines, with widths up to 800mm or more. This increased width provides better stability and control when descending at high speeds.
2. Height and curvature:
Downhill handlebars can have variable rise, as well as a forward or rearward curvature (sweep). These features can be chosen based on the rider's preferences for riding position and comfort.
3. Construction material:
Downhill handlebars are typically made from aluminum, carbon, or composite materials. They must be sturdy enough to withstand the high stresses encountered when descending over rocky and uneven terrain.
Standards:
1. Stem diameter:
Downhill MTB handlebars are designed to mount on stems with common diameters such as 31.8mm and 35mm. It is important to choose a handlebar compatible with the bicycle stem.
2. Grip diameter:
Downhill handlebars are generally compatible with common diameter grips, although some models may have specific diameters to suit the rider's preferences.
In summary, the handlebars of a downhill mountain bike are a crucial element for the rider's control, stability and comfort when riding downhill. With specific features like width, height, and construction material, it's important to choose a handlebar that fits your specific riding needs and downhill riding style.
