Metron Carbon ACR Stem
Vision Metron Carbon ACR Stem – CFD-Designed Aero Carbon Stem with Full Internal Cable Routing
The Vision Metron Carbon ACR Stem is a premium CFD-engineered monocoque carbon stem featuring Vision's fully integrated ACR (Aerodynamic Cable Routing) system, routing all cables, wires and hoses internally for a clean, drag-free cockpit. Developed using Computational Fluid Dynamics technology, the Metron Carbon ACR Stem delivers an ultra-low drag profile without compromising stiffness or strength.
UD carbon fibre construction keeps weight to a minimum while delivering exceptional stiffness for sprinting and climbing. A glossy UD carbon finish ensures the stem enhances the aesthetics of even the most modern aero road bike. Compatible with ACR-equipped frames.
CFD Aero Profile
Developed using CFD technology to create the ultimate low-drag stem profile, the Metron Carbon ACR Stem reduces aerodynamic drag around the cockpit zone for measurable speed gains on the road.
ACR Integrated Cable Routing
The updated ACR system provides a fully integrated Aerodynamic Cable Routing solution, routing all cables, wires and hoses internally through the stem and into the frame — compatible with electronic and mechanical shifting, and hydraulic and mechanical braking.
