This handlebar provides a choice of three common widths—400mm, 420mm, and 440mm—allowing you to match the bar to your shoulder width and preferred riding stance. It is made from carbon fibre, a material frequently used in performance cycling for its potential to offer stiffness where needed while managing overall component weight. The bar features a classic road bike drop shape and is finished with a distinctive 'double line' graphic, available in either a black or red colour scheme against the carbon weave. This combination of fit options, material choice, and visual detail makes it a consideration for road cyclists looking to personalise their bike's cockpit.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/2e41be05-23f4-460e-bd2f-8e61a4ed3959.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe handlebar's design focuses on providing core options for road cyclists. The available widths cover a range suitable for most riders, from a narrower 400mm option to a broader 440mm fit. The construction material and visual design are its primary stated features.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe handlebar is constructed from carbon fibre. In cycling applications, carbon fibre composites can be engineered to provide specific ride characteristics, such as damping high-frequency vibrations from the road or providing lateral stiffness for sprinting and climbing. The manufacturing process involves layering carbon fibre sheets in a mould with resin, then curing it to form a single, strong structure—a method known as monocoque construction. The surface features a 'double line' graphic, which is offered in two colour variants: one with black lines and another with red lines.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eWidth is a critical measurement for handlebar selection, influencing bike handling, rider comfort, and aerodynamics. This bar is offered in three centre-to-centre width measurements: 400mm, 420mm, and 440mm. A 400mm width is often suitable for riders with narrower shoulders or those seeking a more aerodynamic tuck, while 420mm and 440mm widths cater to average and broader shoulder widths, respectively, offering more leverage for steering control. The drop depth, reach, and flare angles are not specified, so it is designed around a traditional road bar geometry.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/31d7447e-45a9-44c5-bb84-2d9b41eee3f7.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis component is designed for a specific role on a specific type of bicycle. Its application is clearly defined by its shape, material, and the width options provided.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor road racing, sportive events, or intensive training, a carbon fibre handlebar like this is a common choice. The potential weight savings and stiffness can be beneficial in competitive scenarios where marginal gains are sought. The range of widths allows both individual riders and team mechanics to select bars that match a rider's physiology and the demands of a particular race course. The graphic options also provide a way to coordinate with a team's or individual's colour scheme without the need for additional tape or paint.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor the dedicated road cycling enthusiast using their bike for daily training, weekend club rides, or commuting, this handlebar offers a performance-oriented upgrade or replacement option. The choice of width can significantly improve comfort on longer rides by ensuring a natural, unstrained arm position. Installing a new handlebar is also a common step in a home bike build or a customisation project, allowing the rider to achieve a desired look with the black or red double-line accent.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/5fb66b3d-d98a-4678-ada6-c3b51286848b.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe value of this product lies in the concrete choices it provides and the inherent properties of its construction material, rather than unspecified performance claims.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eHandlebar maintenance is generally minimal. Once installed correctly with a compatible stem and the appropriate bar tape, a carbon fibre bar requires only periodic checks for security and surface integrity. Unlike some materials, a well-maintained carbon bar is not prone to corrosion. The graphic lines are under the bar tape on the tops and hoods, and on the visible drops, meaning they are largely protected from wear during normal use, helping the bar retain its aesthetic over time.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis handlebar is a suitable choice because it clearly states its key specifications: material (carbon fibre), widths (400mm, 420mm, 440mm), and colour\/graphic options (black double line, red double line). This transparency allows you to make a selection based on measurable, factual criteria that directly relate to bike fit and personal preference. It serves as a functional component that also offers a degree of visual customisation for your road bike's front end.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/611441bb-ee77-4382-9406-8389dca695e2.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/a63f8b73-8d47-4d7d-bb52-c294f2dd41e1.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/a7ee82a5-d359-42f5-8d33-d28cf3f62fd4.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/b9ce4092-7398-43bf-bbe6-df61aedf4f11.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Carbon fibre road bike handlebar showing black double line graphic, with 400mm, 420mm, 440mm width options.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US09\/905\/2025-10-19\/original-image\/c8830ff6-2101-4d8f-aae7-2a80c92c26cc.webp\"\u003e\u003c\/div\u003e","brand":"test3331r0oqb075d","offers":[{"title":"Red Double Lines 400mm","offer_id":58311910654283,"sku":"CJYD201310001AZ","price":74.0,"currency_code":"GBP","in_stock":true},{"title":"Black Double Lines 420mm","offer_id":58311910687051,"sku":"CJYD201310005EV","price":74.0,"currency_code":"GBP","in_stock":true},{"title":"Red Double Lines 420mm","offer_id":58311910719819,"sku":"CJYD201310002BY","price":74.0,"currency_code":"GBP","in_stock":true},{"title":"Red Double Line 440mm","offer_id":58311910752587,"sku":"CJYD201310003CX","price":74.0,"currency_code":"GBP","in_stock":true},{"title":"Black Double Line 440mm","offer_id":58311910785355,"sku":"CJYD201310006FU","price":74.0,"currency_code":"GBP","in_stock":true},{"title":"Black Double Lines 400mm","offer_id":58311910818123,"sku":"CJYD201310004DW","price":74.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1049\/9968\/2379\/files\/5fb66b3d-d98a-4678-ada6-c3b51286848b.webp?v=1788182553","url":"https:\/\/celovian.com\/products\/carbon-fibre-road-bicycle-handlebar-with-400mm-420mm-or-440mm-width-options-in-black-double-line-or-red-double-line-colour-schemes-designed-for-drop-bar-road-and-performance-cycling-applications","provider":"Celovian.com","version":"1.0","type":"link"}
