Road bicycle handlebar carbon fiber 31.8mm clamp diameter 400mm 420mm 440mm widths available in black double line or red double line colour patterns for performance cycling and race builds
Carbon Fibre Road Bicycle Handlebar in 400mm, 420mm, 440mm Widths with Black or Red Double Line

Upgrade your road bike's cockpit with this dedicated carbon fibre handlebar, engineered to be a direct replacement or performance enhancement for modern road and racing bicycles. Its primary advantage lies in its material construction and precise dimensional offering. The handlebar is made from carbon fibre, a material favoured in competitive cycling for its potential to reduce overall component weight. It is available in three specific width options—400mm, 420mm, and 440mm—allowing riders to select a bar that matches their shoulder width and riding style for improved control and comfort. Furthermore, it presents a choice between two distinct aesthetic finishes: a black double line or a red double line pattern, enabling visual customisation of your bike's front end.
Features and Construction

This handlebar is defined by its key specifications and build quality, focusing on compatibility and rider choice. The design centres on practical metrics that influence both bike fit and component interoperability.
Material and Build
The handlebar is constructed from carbon fibre. This material is widely used in performance cycling due to its high strength relative to its weight, which can contribute to a reduction in the bicycle's overall mass and may influence handling characteristics. The construction results in a single, unified component with the stated clamp diameter and width specifications. The surface finish includes a choice of graphic patterns, either a black double line or a red double line, applied directly to the carbon structure.
Size and Practical Fit
The handlebar's fit is governed by two critical dimensions: clamp diameter and width. It features a 31.8mm clamp diameter, which is the standard size for the majority of modern road bike stems, ensuring broad compatibility. The width is offered in three precise increments: 400mm, 420mm, and 440mm. Selecting the correct width is important for rider comfort and control, as it should correspond roughly to the rider's shoulder width. A properly sized handlebar can help reduce strain and improve steering precision.
Uses and Placement

This component serves a specific role within the road cycling ecosystem, from amateur upgrades to dedicated race builds. Its application is tied directly to its technical specifications and material properties.
Event or Professional Use
For riders involved in road racing, sportives, or time trials, a carbon fibre handlebar like this can be part of a weight-saving strategy. The reduction in front-end weight, however slight, is a common consideration in competitive setups. The availability of multiple widths allows racers to fine-tune their aerodynamic position and control feel. The 31.8mm clamp diameter ensures it will fit the high-performance stems commonly used on race bikes.
Everyday Home Use
For the enthusiastic road cyclist looking to upgrade their existing bike, this handlebar offers a clear path to modernising their ride. It replaces older, potentially heavier alloy bars with a contemporary carbon fibre option. The choice of widths means it can be fitted to everything from compact road bikes to endurance models. The colour options—black double line or red double line—also provide an element of personalisation for riders who value the aesthetic cohesion of their bicycle.
Benefits and Buying Value

The value of this product is rooted in its material choice, dimensional options, and role as a core component. It addresses the needs of riders looking for a specific type of handlebar with clear parameters.
Reuse and Low Maintenance
As a structural component, a handlebar requires minimal ongoing maintenance once correctly installed. The carbon fibre construction, when undamaged, is resistant to corrosion. The value lies in its longevity as a part of the bicycle's cockpit; it is not a consumable item but a durable piece of equipment. Care should be taken during cleaning to avoid abrasive materials that could damage the surface finish.
Why Choose This Product
This handlebar is selected for its concrete specifications: carbon fibre construction, a 31.8mm clamp diameter, and a choice of three widths and two colours. It suits a rider who knows the exact width they need and prefers the properties of carbon fibre. It provides a straightforward alternative to standard handlebars without unsupported claims about stiffness or aerodynamics, focusing instead on the measurable facts of its dimensions and material composition.
