Vision Metron TFE Flat

These extensions are specifically engineered to integrate with the Vision Metron 4D Flat M.A.S. base bars. They will not fit standard round handlebars or other base bar models.

The carbon fiber construction is designed to be exceptionally lightweight, minimizing the weight penalty typically associated with adding aero extensions to your cockpit.

The M.A.S. design allows for precise adjustments to the extension length and angle, enabling you to fine-tune your position for better aerodynamics and comfort during long time trial or triathlon efforts.

While these are designed primarily for time trials and triathlons where an aggressive, aerodynamic posture is required, they are intended for use with the Metron 4D Flat base bar system. Always check your local race regulations, as many road racing events prohibit the use of clip-on aero extensions.

Yes, by integrating directly with the base bar, the system creates a cleaner, more cohesive front end. This reduces drag compared to standard clip-on setups, helping you maintain a more efficient position over long distances.
