It is essential to improve the ride quality of your MTB by tweaking its construction even if you are not satisfied with the stock or current setup! At least, carbon fiber MTB bars can help one achieve better control, comfort, and security during a ride!

A right carbon handlebar for your MTB will leave you with lesser pain & aches after your ride. You can better breathe on the climbs and improve the control & cornering on technical terrains with it.

Part1: Buying Guide

While choosing the right product, first you need to have proper knowledge about its specifications. In this manner, you could make a better-informed decision. Let us uncover the main specs of carbon fiber MTB handlebars, including the suggestions for the buyers to choose the best;

Materials & Weight

Generally, Titanium, Alloy, or Carbon are useful to make the handlebars. Among them, Carbon handlebars are more prevalent than others. These are light in weight and consist of flex patterns for more methodically placement of the bars.

Lightweight bikes are considerably better for mountain biking. Thus, you can cut much of its weight by replacing the stock handlebar of MTB with a carbon fiber option.

Rise & Sweep

These factors decide the overall design of the handlebar. Many configurations of different sweep and rise options among handlebars are available in the market. The rise means the vertical rise of the handlebar from its center to the end. It usually varies amid a 40 mm rise but gets even taller to raise the height of the handlebar in a bike.

Sweep is the bend provided in the handlebar and characterize among back sweep and up sweep. You need to look at it from the front, you will find it! Upsweep is the angle amid the parallel imaginary line as per the clamping surface and perpendicular to the handlebar rise. While seeing from the top-down view, the back sweep is the angle between the imaginary lines of the clamping surface to the handlebar.

If you mostly ride in extremely steep terrain, a handlebar with a higher rise might benefit you. A low raise bar can help you keep the weight at the bike front while riding in the steep climbs. A higher rise is vital to put your weight on the back of a bike on steep trails.

Upsweep is a little bit of rising to get the better neutral position of the wrist while riding. A back sweep in the handlebar is also to help in wrist comfort and position during off-roading by angeling the bar ends towards the rider. In comparison to the flatter bar, the more back sweep that a handlebar is having different will be the position of your upper body.

Upgrading to another handlebar with a different back sweep or/and upsweep is convenient. It is good if you have the right idea about the handlebar configurations currently present in your mountain bike. You can go with another configuration that fits well with your use case.


It is for personal preference or to enhance the rider’s comfort as per the local terrain, riding style, and body dimensions. For instance, a taller rider would not like to use the handlebar with a width suitable for not-so-tall riders. A wider handlebar is more stable than a narrower one. However, a narrower bar gives a better sitting position to the biker, so to cover long mile with better endurance.

A less wide handlebar is better for the area having trees and tight trails! In case, you are riding in a dessert, then prefer using a wide handlebar. In this way, the obstacles of taller height would not make any issues. So you do need to consider all such small factors to choose the right width of the handlebar.

If you feel confused about the right width for your purpose, you could prefer to go with the wider one. After all, they consist of designs with cut marks so that if you need, you can cut them down for a few millimeters on each side to narrow it down. The width of a carbon MTB handlebar varies between 750 mm to 800 mm.

The handlebar of the bike is more capable with slacker, and longer geometries. Hence, its handlebar must also be wider for better control and leverage. So, the ridder would be in an ‘attacking’ position. The wider handlebar in the slacker bikes makes them run more stable on the steep bits, jumps, or corners of the trail.

More leverage means a rider can manipulate the front part of the bike. It is possible by lessening the total force required to control the bike while steering, aft & fore, and side to side. A wider handlebar might not be comfortable for all users depending on body size.

Clamp Diameter

Many people have confused among 31.8mm and 35mm options of clamp diameter in the handlebars. The 35 mm clamp diameter stems and handlebars are for a potential increase in durability and stiffness. You can’t only go with more stiffness.

The combo of stem and handlebar is compliant with the trail’s vibration. Both the diameter options can give the same strength. It is a fact that 35 mm diameter handlebars are lighter in weight than the 31.8 mm options. One should have enough flex as per the comfort of the rider.

The bore size or clamp diameter of the handlebar is its width here it matches with the stem. It tapers gradually to the end, where grips are present. The standard clamp diameter found in many handlebars years ago is 31.8mm.

Some DH bikes came with 35 mm clamp diameters. Most of the stem/handlebar interfaces provide more stiffness on the thicker tube circumference. This time, 35 mm handlebar options are lighter than the olden 31.8 mm standard. It is for more variable performance characteristics and durability.

You can find many trail and XC bikes with 31.8mm bikes. The modern endure trail bikes possess 35 mm bars and stems. If comfort and compliance are your preference, you can choose a narrower 31.8 mm bore size. For stiffer and more aggressive rides, you can choose 35 mm. By the way, changing the clamp diameter also demand you to change the stem of compatible size.

Control, Compliance, and Stiffness

Compliance is the material’s elasticity or the possibility of defamation against a force. Stiffness is the ability of a material to resist deformation against force. The handlebars of mountain bikes are tapered intentionally right at the center. It is to make a section on the bar with different compliance characteristics and stiffness.

Such individual separations determine the overall ability of the handlebar. The aim here is to absorb flex, chatter under force at the ends, and be stiff at the center to maintain steering leverage and accuracy. Some riders choose a highly stiff bar to enhance their steering and control input on the bike. The other riders prefer a highly compliant bar that reduces hand fatigue and absorbs trail feedback.

Part2: Selection Guide

Do not blindly go with what your colleague or riding partner prefers to use for the right handlebar for a mountain bike! There are varieties of color and geometry options available with unique technology and features. One can help you improve the overall quality of the product. As per some classifications following are some types of Handlebars suiting to different needs of riders;


This kind of mountain bike mostly has the highest rise bars. So for a steep terrain descent, you can manage your weight on the rear wheel.


There are many types of handlebar setups available for these bikes. Carbon MTB bars can handle more vibrations that make your hands feel comfortable in the long or daily run. You can pick one from 10 mm – 35 mm rise to fit with your endurance or trail with ease.
