Vision's Metron Carbon ACR stem pairs a low-drag carbon shape with fully internal cable routing. Vision shaped it with Computational Fluid Dynamics (CFD), and the UD carbon construction keeps weight down while staying strong and stiff for hard sprints and climbs.

Highlights

  • Monocoque UD carbon body with an alloy faceplate
  • Titanium hardware
  • ACR (Aerodynamic Cable Routing) runs all cables, wires and hoses internally
  • 31.8 mm handlebar clamp, -6° angle and 35 mm stack height
  • Four lengths from 100 mm to 130 mm

Built for modern aero road bikes

A glossy UD carbon finish suits today's aero road frames, and Vision lists the stem for road, triathlon and gravel riding. ACR is Vision's patent-pending routing system: it draws on the brand's headset and cockpit design to give frame and bike brands a clean, integrated and aerodynamic front end.

Compatibility & fit

Vision lists this stem as suitable for ACR frames, so check that your frame and headset are built for ACR routing before ordering. It clamps a 31.8 mm handlebar and has a 35 mm fork clamp stack height. Carbon parts need the correct bolt torque, and our workshop can fit the stem, route the hoses and wiring, and bleed the brakes.

Options

Length100mm, 110mm, 120mm, 130mm
