31.8 Bike Handlebar 780mm Riser - Comfortable Wide MTB Bar

In this review the GEWAGE 31.8 bike handlebar is evaluated for riders who want a modern, wide riser bar that prioritizes control and a more upright position. The single biggest reason to buy is its combination of a full 780 mm width and multiple rise options, which makes it easy to tailor fit the handlebar to trail, jump, or commuter style riding while keeping wrist and shoulder comfort in mind. It feels like a thoughtfully designed, no-nonsense upgrade for most mountain bikes and dirt bikes.

Key Features

• 780 mm width: The extra width improves leverage and stability on technical trails and when landing jumps, making bar control more confident.
• 6061 aluminum alloy construction: Delivers a balance of stiffness and durability so the bar stays responsive through hard riding while resisting damage.
• Multiple rise options: Available in 25 mm, 55 mm, 70 mm, 90 mm and 120 mm so riders can choose a rise that promotes a more upright, comfortable posture.
• 12 degree rearward sweep: The geometry positions shoulder blades and hands more neutrally to reduce wrist fatigue on longer rides.
• Non-slip finish: A tactile surface that helps grips and controls stay in place even in wet or rough conditions.

Who It's For

This handlebar suits mountain bikers, trail riders and dirt jumpers who want a wide, durable bar with options for different rises to tune cockpit height and comfort. Riders who value an upright or slightly more relaxed posture will appreciate the 12 degree sweep and taller rise choices like 90 mm or 120 mm.

It is less appropriate for riders who need ultra-lightweight carbon components for weight-critical cross-country racing or those who prefer very narrow bars under 780 mm; a few users noted the width can feel narrower than older, wider bars they replaced.

Pros & Cons

Pros

• Well made with a solid finish and a durable 6061 aluminum build that stands up to rough trail use.
• Ergonomic 12 degree sweep and several rise choices that effectively reduce wrist strain and encourage an upright riding position.
• Wide 780 mm span gives improved control and better leverage for technical maneuvers and jumps.

Cons

• Some riders may find the 780 mm width narrower than their previous bars, so check fit before committing.
• Aluminum construction trades off a small amount of vibration damping compared with premium carbon bars.
