Metron 81 SL Wheelset - Rim Brake
Vision Metron 81 SL Wheelset – Deep-Section Aero Power for Triathlon & Time Trial
The Vision Metron 81 SL is a purpose-built aero carbon wheelset engineered for maximum speed in triathlon and time trial racing. With its deep 81mm full-carbon rim, CFD-validated shaping and proven race pedigree — including 100+ pro podiums — this wheelset delivers the aerodynamic efficiency, stability and responsiveness demanded by elite athletes.
Featuring a 24.8mm external rim width, direct-pull aero spokes, and Vision's smooth-rolling P.R.A. hub system with six sealed cartridge bearings, the Metron 81 SL maintains speed effortlessly while offering predictable handling in varying wind conditions. Vision's laser-etched micro-dot brake surface provides exceptional rim-brake stopping power and control in all weather.
Deep 81mm Aero Rim Profile
A full-carbon 81mm rim optimised for straight-line speed — ideal for triathlon bike legs, time trials and high-velocity road racing. The deep-section profile minimises aerodynamic drag so you can hold higher speeds with less effort, giving you a measurable advantage over every kilometre of the course.
CFD & Wind-Tunnel Proven Aerodynamics
Developed using advanced aerodynamic modelling and real-world wind-tunnel testing, the Metron 81 SL's rim shape is optimised to minimise drag and maximise stability across a wide range of yaw angles — so you stay fast and in control even when the wind picks up.
P.R.A. Hubs with Direct-Pull Spokes
Aero-bladed direct-pull spokes reduce turbulence and improve stiffness, while the 2:1 lacing pattern (16F / 21R) ensures balanced tension and efficient power transfer. Six sealed cartridge bearings deliver smooth, efficient rolling for the duration of your race.
Enhanced Rim-Brake Performance
The laser-etched micro-dot brake track dramatically improves braking consistency, modulation and wet-weather control — giving rim-brake riders the confidence to push harder into every corner and descent.
Hand-Built Craftsmanship
Every Metron 81 SL is artisan-built entirely by hand for perfect spoke tension, long-term reliability and premium ride quality that performs race after race.
