The CEC #440 Carbon Handlebar embodies technical excellence for gravel and ultra-distance enthusiasts. Designed by Carbon Endurance Component, a brand founded by Pierre-Arnaud Le Magnan (creator of Chiru Bikes and with over 35 years of experience in composites), this handlebar boasts a featherweight of 240 grams without compromising stiffness or reliability. Tested on the most demanding terrain by the Chiru Brigade around the world, the CEC #440 combines optimized geometry, long-distance comfort and premium finish.

Technical Highlights

• High-performance T700 carbon: monocoque composite offering exceptional stiffness and vibration absorption, ideal for long rides on rough tracks and trails.
• Gravel-specific geometry: 440 mm width (center to center), moderate 14° flare for optimal control on descents, 4° backsweep for ergonomic wrist comfort.
• Low weight: only 240 g, among the lightest on the market for a solid carbon gravel handlebar.
• Matte clear coat finish: clean aesthetic that reveals the carbon texture, durable protection against UV and weather.
• Universal clamp diameter: 31.8 mm compatible with most modern road and gravel stems.

Ergonomics and Long-Distance Comfort

The 14° flare offers an ideal compromise between stability on technical descents and comfort in the hoods when riding. The 4° backsweep naturally aligns the wrists with the forearms, reducing muscle tension and numbness on multi-hour rides. The handlebar profile has been designed to offer multiple comfortable hand positions: on the tops, on the hoods or in the drops — crucial for ultra-distance and bikepacking. The slightly flattened upper section improves grip and control, while the wide clamping area ensures secure attachment.

Field-Proven Design

Developed after two years of intensive testing by Team Chiru in adventure races and ultra-endurance events (Tour Divide, Atlas Mountain Race…), the CEC #440 has been pushed to its limits on all types of terrain. This field validation refined the carbon layup, geometry and finish to achieve an optimal balance between lightness, stiffness and resilience. The T700 carbon used benefits from a precise manufacturing process that eliminates weak spots and guarantees exceptional durability, even in the most extreme conditions.

Versatility and Compatibility

Designed primarily for gravel and endurance, this handlebar also adapts perfectly to bikepacking bikes or versatile road setups. Its design allows for internal cable/housing routing depending on your frame and stem configuration. Compatible with hydraulic and mechanical brake levers, it also accepts mounting systems for computers or lights. The 440 mm width suits riders with medium to large builds (shoulder width ~42-46 cm), providing breathing room on climbs and stability on fast gravel descents.

Carbon Endurance Component Philosophy

CEC pursues a clear mission: to produce reference-grade carbon components for endurance and bike adventure, combining composite innovation, artisanal craftsmanship and extreme field validation. Each CEC component is designed to meet the demands of cyclists who push their limits, whether on a Sunday gravel ride or a self-supported transcontinental crossing. The #440 embodies this philosophy: a reliable, high-performance and durable tool that will accompany you on all your playgrounds.
