Ready for both training and competing, this road bike handlebar is kitted out with a continuous carbon composite construction for maximum stiffness and strength without adding any unnecessary excess weight to your ride. Its reinforced carbon fibre build also ensures a great strength to weight ratio, while its unidirectional (UD) carbon finish keeps its weight low. Mixing aerodynamics and ergonomics, Vision has equipped this model with a unique shape that uses an Aero-Ergo central section for smooth, agile and efficient handling as you change position and maintain your momentum. Another highlight is its internal cable routing with guides that accommodate wiring for electronic shifting, making it ideal for use with Di2 systems. Coming complete with a traditional design with comfortable geometry, the Metron 6D integrated handlebar is classed as the stiffest and most aero-integrated handlebar and stem system from Vision.  Technologies: Aero-Ergo: Mixing aerodynamics and ergonomics, the unique shape includes our Aero-Ergo central section.
