Deda Superzero RS Carbon Bars: A Blend of Tradition and Modern Innovation

The Deda Superzero RS Carbon Bars, in their 42cm iteration, represent a sophisticated fusion of time-honored handlebar ergonomics and contemporary carbon fiber engineering. This offering aims to satisfy riders who appreciate a classic form while benefiting from modern advancements in materials and design. These handlebars deliver a noteworthy combination of stiffness for efficient power transfer and comfort for extended rides, complemented by features like internal cable routing. While they reside in the upper echelons of pricing and present a slight challenge in brake hood positioning, their overall quality and performance firmly establish them as a competitive option within the high-end cycling component market, particularly for those who value a traditional, non-flared design.

Crafted from unidirectional carbon fiber, the Superzero RS Carbon handlebar is designed with an aerodynamic flat-top section that gracefully transitions into a curved drop. This distinctive shape, referred to by Deda as RHM-EVO, features a 75mm reach and a 120mm drop, providing a comfortable and effective riding position. Uniquely, Deda measures handlebar width from outside-to-outside, meaning the 42cm model reviewed here is comparable to approximately 39cm when measured from center-to-center, a common standard among other brands.

The construction prioritizes both lightweight performance and structural integrity. The 42cm test sample registered a weight of 240g, aligning closely with the manufacturer's stated weight of 235g. This minimal variance underscores the precision in its manufacturing. Despite the tight curvature inherent in its design, the process of installing brake hoods proved to be relatively straightforward. However, an observation was made regarding the suboptimal placement of the positioning markers for the brake levers, which necessitated careful alignment to achieve a seamless transition from the handlebar to the hood, especially with SRAM Force AXS levers.

Connectivity and integration are also key aspects of these handlebars. They are fully compatible with Deda’s DCR (Deda Internal Cable Routing) system. Thoughtfully positioned cable ports and routing channels facilitate a clean and efficient cable setup. The design includes a standard-sized opening, allowing for full integration with compatible frames where cables can route through the stem and into the frame. Additionally, cable ports at the ends of the flat-top section enable neat semi-internal routing, ensuring a tidy aesthetic. The extensive decals spanning the flat-top section further enhance visual appeal, particularly for riders who opt for minimal bar tape application.

On the road, the Superzero RS Carbon handlebars offer an excellent riding experience. The flat-top profile is ergonomically sculpted, providing a natural and comfortable grip, with ample depth to support the wrists. The traditional Italian design, characterized by a lack of flare and a pronounced curve into the 120mm drops, will resonate with enthusiasts of classic road cycling aesthetics. For those requiring more width and control, especially in off-road conditions, Deda also provides a Gravel variant featuring a 16-degree flare. The clamping area, measuring 83mm wide, offers sufficient space for various stems, as well as essential accessories like out-front computer mounts and lights. Furthermore, the handlebars are compatible with Deda’s Fast Pro Extensions, although, typical of many aero handlebars, adjustment and mounting space may be somewhat restricted.

The handlebars excel in ride quality, effectively dampening vibrations without introducing any harshness. Their stiffness is equally impressive; even under intense sprinting efforts and vigorous pulling movements, no discernible flex was observed. This robust performance contrasts with other aero options, such as the Deda Vinci, which, despite similar weight and price, exhibits more flex in the drops. While the Superzero RS Carbon’s aerodynamic profile is less extreme than that of the Vinci, it still contributes to an efficient setup. Positioned at a price point of £299, these handlebars compete directly with other premium offerings like the Roval Rapide (£350) and the FSA K-Wing AGX (£240). Although they provide solid performance across key metrics like stiffness, comfort, and modern cable management, they do not present a revolutionary feature that distinctly separates them from their peers. Riders prioritizing a traditional, non-flared handlebar shape will find the Deda Superzero RS Carbon Bars to be a high-quality, high-performing option, albeit one that doesn't significantly redefine its category.
