MTB Handlebars: How to Choose the Right Setup
MTB handlebars (also known as mountain bike bars or MTB bars) are designed to improve control, comfort and stability on rough terrain. The right handlebar affects how your bike climbs, descends and responds through corners.
Whether you're upgrading to carbon MTB handlebars for weight savings or switching to high rise MTB bars for better control, small changes can significantly improve ride feel and confidence.
Pair your MTB handlebars with the right MTB grips to improve comfort and control on trails.
Types of MTB Handlebars
Flat Bars (XC-Focused)
Flat MTB handlebars have no rise and position the rider lower over the front of the bike.
- Ideal for cross-country (XC) riding.
- More efficient climbing position.
- Responsive handling on smoother terrain.
Flat bars suit riders who prioritise speed and pedalling efficiency.
Riser Bars (Trail & Enduro)
MTB riser bars are the most common setup for modern Trail and Enduro bikes.
- Available in multiple rise options from 15mm to 80mm.
- More upright riding position. Taller riders will benefit from a tall front end, unless you have great flexibility.
- Better control on descents.
Mountain bike riser bars help keep your weight centred, making them ideal for technical terrain and aggressive riding.
High Rise MTB Bars
High rise mountain bike bars are designed for comfort and control, especially for taller riders or steeper terrain.
You'd consider a high-rise bar if you're a taller rider on a 120/130/140mm (front) travel XC or Trail bike bike. Or you're riding an Enduro bike but leaning to far forward.
A high-rise bar will give you a:
- More upright position.
- Reduces pressure on hands and lower back.
- Improves confidence on descents because you're more centred between the front and rear wheels.
High rise bars are also useful if your bike feels too stretched out. Because it effectively shortens the reach.
Carbon vs Aluminium MTB Handlebars
Carbon MTB Handlebars
Carbon mountain bike handlebars are lightweight but also help reduce trail vibration.
- Improved comfort on long rides.
- Reduced arm fatigue because these bars flex to absorb impacts and vibrations.
- Popular for performance-focused builds.
Aluminium MTB Handlebars
Aluminium MTB bars offer excellent durability and value.
- Alloy bars are strong and impact-resistant.
- They are more affordable than carbon handlebars.
- Suitable for most riders and conditions.
Clamp Diameter: 31.8mm vs 35mm
The clamp diameter is where your stem attaches to the handlebar.
- 31.8mm clamps are used on most hybrids, flat bar roads bikes and hardtail mountain bikes. These encourage a little more flex than the larger 35mm clamp handlebars.
- 35mm bars have a stiffer setup for precise handling and aggressive riding. These are featured on (most) dual-suspension mountain bikes.
When upgrading MTB handlebars, make sure your stem's clamp diameter matches. Otherwise consider a bike stem upgrade if you want something nicer or want to fine tune your handling.
MTB Handlebar Width
Handlebar width affects stability, control and body position.
- Wider bars improve leverage and control on descents.
- Narrower bars are more manoeuvrable on tight trails.
Rise and Riding Position
Rise refers to how much higher the bar sits relative to the stem.
- Flat bars (0mm rise) – Better for climbing and efficiency
- Riser bars (10–40mm+) – Better for control and descending
More rise creates a more upright position, while less rise puts you in a more aggressive stance.
