The Metron 5D Integrated Handlebar is one of the stiffest and most aerodynamic handlebar-stem units on the market. Thanks to the special Aero-Ergo top bar and its unique shape, the handlebar uniquely combines aerodynamics with ergonomics. A slight rise and a 10° front sweep support the natural arm position for maximum comfort and unrestricted breathing. At the same time, the airfoil shape of the top bar ensures optimal aerodynamics. The reinforced carbon fiber construction gives the 5D a great strength-to-weight ratio. The 5D also features internal cable routing (even for electronic shifting systems).
