Metron 91 SL Front Wheel - Disc Brake
Vision Metron 91 SL Disc Front Wheel – The Ultimate Aero Front Wheel for Triathlon & Time Trial
The Vision Metron 91 SL Disc is engineered for one purpose: pure aerodynamic speed. Designed specifically for triathlon and time trial racing, this 90mm deep carbon front wheel delivers exceptional stability, low drag and proven race-winning performance. With a 33.6mm external rim width, direct-pull aero spokes, and CFD-validated shaping, the Metron 91 SL has already earned 100+ pro podiums — a testament to its reliability and unmatched aero efficiency.
Built around Vision's complete wheel system, the Metron 91 SL combines advanced carbon construction, precision hub engineering and hand-built craftsmanship to create a triathlon front wheel trusted by elite athletes worldwide.
Deep-Section Aero Advantage
A full-carbon 90mm deep clincher rim designed to minimise drag and maximise straight-line speed. Whether you're racing an Ironman bike leg or a time trial course, the Metron 91 SL gives you the aerodynamic edge that separates podium finishers from the rest of the field.
CFD & Wind-Tunnel Proven
Developed through extensive aerodynamic testing, the Metron 91 SL's rim profile and spoke configuration are optimised for stability, efficiency and predictable handling at high speeds — so you can focus on pushing harder, not fighting your equipment.
PRS Hub System with Direct-Pull Spokes
Aero-bladed direct-pull spokes reduce turbulence and improve stiffness, while the 2:1 lacing pattern ensures balanced tension and efficient power transfer. Six sealed cartridge bearings deliver smooth, durable rolling in all conditions.
Hand-Built Precision
Every Metron 91 SL is artisan-built entirely by hand for perfect spoke tension, long-term reliability and consistent race-ready performance — because when you're racing against the clock, every detail matters.
