FIFTY-FIFTY Mountain Bike Riser Handlebar 31.8mm 780mm - Control

In this review the FIFTY-FIFTY Mountain Bike Riser Handlebar stands out as a practical upgrade for riders who want a wider, lightweight bar that improves control. The single biggest reason to buy is the balance of strength and weight: high-grade 6061 aluminium with double butting and hard anodizing keeps the bar durable while the 35mm and 50mm rise options remain surprisingly light, making it a good choice for all-mountain and trail riders seeking better handling without a heavy penalty.

Key Features

• Durable construction: The 6061 aluminium alloy and double butted tubing provide reliable strength for aggressive riding and long-term use.
• Lightweight options: The 35mm rise weighs about 340g and the 50mm rise about 460g, keeping bike weight down while adding desired height.
• Extra-wide profile: At 780mm the bar gives more leverage for steering and stability when tackling technical terrain.
• Improved comfort and control: The riser shape moves the rider into a more controlled, comfortable position for descents and technical climbs.
• Setup and cut-down markings: A central setup grid and side cut marks let you trim the bar precisely to common widths like 680mm or 740mm.
• Precision bending: Numerical controlled bending and hard anodizing enhance finish and consistency across bars.

Who It's For

The FIFTY-FIFTY riser bar is best for trail and all-mountain riders who want a wider handlebar to improve bike handling and stability on technical sections. Riders who value a light component without sacrificing strength will find the 35mm rise especially appealing for mixed climbing and descending.

It is less suitable for riders who need ultra-narrow bars for tight singletrack or those who prefer flat bars with zero rise; commuters and casual riders who prioritize position over aggressive control should consider a different style more focused on upright comfort.

Pros & Cons

Pros

• Excellent build quality and finish thanks to 6061 aluminium, double butting and hard anodizing.
• Wide 780mm width delivers improved control and leverage on technical terrain.
• Lightweight rises (35mm at ~340g and 50mm at ~460g) keep overall bike weight competitive.
• Clear setup grid and cut marks simplify installation and width customization.

Cons

• 780mm may be too wide for riders who prefer narrow bars or ride very tight singletrack.
• Only two rise options may not suit riders seeking very low or very high rise beyond 35mm or 50mm.
