What Our Gearhead(R) Experts Are Saying: "I tested the Metron RS 37 on rolling terrain and was blown away by how responsive and quiet they are. The carbon spokes and V-1000 hubs keep power transfer super tight, and the 23mm internal width makes tubeless setup seamless. Lightweight, aero, and seriously fast."When we want every watt to count, the Vision Metron RS 37 Carbon Wheelset delivers elite-level performance from the first pedal stroke to the finish line. As Vision's first full carbon wheelset-rim and spokes included-the Metron RS 37 blends advanced carbon layups with a wind-cheating 37mm profile that feels as confident on punchy climbs as it does slicing through a headwind. The new V-1000 hub is equipped with PRS tech for reduced drag and faster engagement, while 6 sealed cartridge bearings keep things silky smooth over the long haul. We're big fans of the 23mm internal width, which improves tire profile for more grip and control. From the handmade build to the bladed aero carbon spokes, every detail is engineered for speed and backed by wind-tunnel proven design.
