Vision Metron 4D Aero Road Bar

Mixing aerodynamics and ergonomics, the unique shape of the Metron 4D includes Vision's Aero-Ergo central section. With a slight rise from the stem clamp and a 10 degree forward bend, the 4D accommodates the natural position of your arms for more comfort and easier breathing, while the wing-like shape of the bar top aids aerodynamics. Kevlar-reinforced carbon fiber construction gives a great strength-to-weight ratio. The 4D features internal cable routing, with guides that accommodate wiring for electronic shifting.
