Metron 5D integrated handlebar, the stiffest and most aero integrated handlebar and stem system. Mixing aerodynamics and ergonomics, the unique shape includes our Aero-Ergo central section. With a slight rise from the stem clamp and a 10 degree forward bend, the 5D accommodates the natural position of your arms for more comfort and easier breathing, while the wing-like shape of the bar top aids aerodynamics. Reinforced carbon fiber construction gives a great strength-to-weight ratio. The 5D features internal cable routing, with guides that accommodate wiring for electronic shifting. Now available with the new ACR System, a fully integrated Aerodynamic Cable Routing solution that routes all cables, wires, and hoses internally. Aerodynamic integrated Cable Routing (ACR) All carbon construction Di2 compatible with integrated junction box compartment and wiring conduits 5mm offset drops providing wider, more stable sprinting platform and allowing faster transitions from hoods to drops Stem angle: -6° VISION ACR SYSTEM VISION ACR System is a fully integrated Aerodynamic Cable Routing solution that routes all cables, wires and hoses internally. This innovative patent-pending system is unique to VISION and is a combination of our knowledge bases in both headset and cockpit development and manufacturing plus our history in aerodynamic development and design. The result is a clean, integrated and aerodynamic cable routing solution for frame and bicycle brands.
