Buying Guide
Key purchase considerations
- Clamp diameter: Most mountain bikes use 31.8 mm, with some bikes or bars at 25.4 mm. Choose the diameter that matches your steerer tube/handlebar compatibility.
- Width: A wider bar (e.g., 780 mm) increases stability on descents but can be harder to maneuver in tight trails. A 620–620 mm width suits smaller frames or tighter trails.
- Rise: The rise determines how high your handlebars sit relative to the stem. Higher rises (90–120 mm) promote an upright posture and back comfort, while lower rises favor aggressive, forward-leaning positions.
- Backsweep and upsweep: These angles affect wrist and shoulder comfort. More backsweep can reduce wrist strain; upsweep helps keep wrists in a natural alignment during climbs.
- Material and durability: Aluminum alloys like 6061 or 2014 offer strong, lightweight performance with good vibration dampening. Consider weight, stiffness, and finish when selecting.
- Compatibility and installation: Check for compatibility with your stem, headset, and bar ends. Some handlebars include or require specific bar-end shapes.
Comparisons by riding style
Trail riders often prefer moderate-to-wide bars (700–780 mm) with mid-to-high rises (60–120 mm) for control and comfort. Endurance riders may favor slightly narrower widths with moderate rises to balance aerodynamics and comfort. For aggressive climbing or long descents, a higher rise and ergonomic backsweep help maintain a neutral wrist posture and reduce fatigue.
Material and performance considerations
6061 aluminum bars are common for their balance of weight, stiffness, and value. Some models use 2014 aluminum for improved chatter dampening. When possible, test the bar’s feel in a local shop or ride with a similar setup to verify comfort, steering response, and vibration reduction on the trails you ride most.
