Vision Metron 4D Flat M.A.S. Time Trial Handlebar - S-Bend

Vision Metron 4D Flat M.A.S. Time Trial Handlebar - S-Bend

The Vision Metron 4D Flat TT handlebar combines the outstanding ergonomic as well as aerodynamic properties of the Metron 4D dropbar with a lower hand position and the innovative M.A.S. (Modular Aero System) clip-on aerobar system that offers even more versatility.

The reinforced carbon fibre construction gives the dropbar an excellent stiffness-to-weight ratio, while its top section with 10° pre-bend not only allows for a natural arm position, but also an ergonomic riding position when riding uphill as well as free breathing. For internal routing of cables as well as electronic wires, the Metron 4D handlebar features the ACR (Aerodynamic Cable Routing) system.

The M.A.S. Direct Mount clip-on aerobar also gives the rider greater flexibility in positioning what also expands the range of possible applications. Available with J-Bend and S-Bend extensions.


Highlights of the Metron 4D dropbar/aerobar combination

  • handlebar with continuous carbon composite construction
  • ergonomic aero top section with pre-bend for a natural posture
  • reinforced, roughened clamping area for brake lever and stem
  • prepared for Aerodynamic Cable Routing (ACR)
  • cable channels for internal cable routing (Di2 compatible)
  • equipped with M.A.S. Direct Mount clip-on aerobar system (removable)
  • 31.8 mm clamp diameter
  • 125 mm Drop / 80 mm Reach
  • 10° forward angle / 2° outward bend


ACR (Aerodynamic Cable Routing)

The ACR system is a fully integrated aerodynamic cable routing solution that routes all cables, wires and hoses internally through handlebar and stem.

Built around the headsets and integrated cockpits produced by FSA and Vision, the ACR technology represents a "plug-in" solution for a clean and simple cable routing. By using standard headset dimensions, frame and steerer strength are not affected.
