Metron 81 SL Wheelset - Rim Brake
Vision Metron 81 SL — Deep‑Section Aero Power for Triathlon & Time Trial
The Vision Metron 81 SL Clincher/TL is a purpose‑built aero 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 is designed to maintain speed effortlessly while offering predictable handling in varying wind conditions. For rim‑brake performance, Vision’s laser‑etched micro‑dot brake surface provides exceptional stopping power and control in all weather.
Key Performance Highlights -
Deep 81mm Aero Profile: A full‑carbon 81mm rim optimised for straight‑line speed, ideal for triathlon bike legs, time trials and high‑velocity racing.
CFD & Wind‑Tunnel Proven Aerodynamics: Developed using advanced aerodynamic modelling and real‑world wind‑tunnel testing to minimise drag and maximise stability.
P.R.A. Hubs with Direct‑Pull Spokes: Aero‑bladed DP spokes for stiffness and reduced turbulence. 2:1 lacing pattern (16F / 21R) for balanced tension and power transfer. Six sealed cartridge bearings for smooth, efficient rolling.
Enhanced Rim‑Brake Performance: Laser‑etched micro‑dot brake track dramatically improves braking consistency, modulation and wet‑weather control.
Hand‑Built Craftsmanship: Each wheel is artisan‑built entirely by hand for perfect tension, long‑term reliability and premium ride quality.
