Metron 4D Flat M.A.S
Mount the Vision Metron 4D Flat M.A.S for an anatomically-adjustable aerodynamic advantage when every split-second is counting against you. This modular aerobar combines the comfortable ergonomics of the Metron 4D Flat road bar with an innovative direct-mount clip-on Modular Aero System (MAS), giving you added versatility for time trial and triathlon events. The unidirectional carbon fiber construction ensures a high strength-to-weight ratio, and the bar features internal cable routing with guides that accommodate wiring for Di2 electronic shifting. And because the base bar is simply the Metron 4D Flat road bar, it's compatible with conventional stems that use a 31.8mm clamp diameter for greater ease of use.
