The Deda Vinci stem is the first stem designed to enable fully integrated cable routing when combined with Deda handlebars featuring the DCR (Deda Internal Cable Routing) system. It delivers cutting-edge performance, sleek aesthetics, and advanced compatibility for modern racing bikes.

Versatility defines Vinci: this stem is compatible with both 1-1/8” and 1-1/4” fork steerers. The DCR system works seamlessly with standard tapered steerers (1-1/8” upper diameter) but requires a 52mm (1.5”) upper headset bearing OD. A rear opening leaves space for cables to pass cleanly between the headset bearing and the fork.

The Vinci stem system includes special slotted spacers designed to guide cables and simplify adjustments. Thanks to their pull-open design, spacers can be added or removed without disconnecting all cables, making setup and maintenance quick and efficient.

Built with innovative 3D forging technology, the Vinci stem combines lightweight construction with maximum stiffness. Its flat aero design improves aerodynamics, while the included aero integrated top cap, headset spacers, and alloy sleeve adapter for 1-1/8” fork steerers complete the system.
