Deda Vinci Alloy Integrated Stem

The Deda Vinci Integrated Alloy Stem is an advanced cockpit solution engineered to enable seamless, fully integrated internal cable routing when paired with Deda DCR handlebars. Manufactured using high-precision 3D forging techniques from high-grade aluminium alloy, its flat aero profile reduces drag while providing exceptional lateral rigidity for high-effort sprinting, climbing, and competitive road racing. Positioned as one of the most versatile integrated stems on the market, the Vinci features a dual steerer compatibility system. It natively fits 1-1/4" steerer tubes and includes a custom alloy sleeve adapter to work seamlessly with standard 1-1/8" fork steerers. When paired with a 52mm (1.5") upper headset bearing, the DCR design directs up to four cables through a dedicated internal cavity behind the stem body, completely hiding mechanical cables, electronic wires, and hydraulic hoses from the airflow. Fine-tuning fit and stack height is straightforward thanks to Deda’s slotted spacer system. The included aero spacers feature open slits, allowing them to be added or removed beneath the stem without disconnecting hydraulic brake lines or shifting cables. Secured by high-strength black steel bolts and finished in Deda’s refined Polish on Black (POB) graphics, it includes an aero topcap and dedicated headset adapters out of the box.
