Vision Metron 4D Handlebar Info
The Vision Metron 4D Handlebar blends aerodynamic innovation, climbing comfort, and race-grade construction to satisfy riders who want more than just a drop bar. Featuring Vision’s Aero-Ergo central section with a 10° forward bend, the 4D puts you in a more natural arm posture for better breathing and comfort.
Made from continuous carbon composite, this handlebar includes internal cable routing compatible with modern electronic drivetrains. Reinforcements in the stem clamp and lever clamp zones boost stiffness and durability, while the flat/tapered top section aids aerodynamics without compromising hand positions on long climbs or flats.
