Vision expands the Metron range, specially designed for unparalleled performance in terms of speed, comfort and efficiency.
Vision’s dedicated triathlon range for maximum performance includes three new products: the Metron TFE Team Edition extension for optimal aerodynamics and comfort, the Metron TTW wheel with lenticular disc for extreme speed in time trials, and the Metron 91 SL wheel, created to tackle Kona’s crosswinds. Together, these products form a winning combination for athletes who want to push their limits.
These components are not just individual parts, but are developed to work in harmony, creating a cohesive setup that allows athletes to perform at their best, minimizing drag and maximizing speed and comfort in the most demanding endurance races.

METRON TFE TEAM EDITION
The Metron TFE Team Edition represents Vision’s latest advancement in aerodynamic extensions. Developed in collaboration with World Tour athletes, the TFE Team Edition features a 20-degree raised platform , a deeper extension profile, and improved ergonomic pads for a customized fit. This semi-custom solution allows athletes to achieve the perfect balance between comfort and speed, making it the premier choice for elite triathletes.

CFD simulations reveal the superiority of the 2024 Metron TFE Team Edition over the 2021 version, the TFE PRO. At a speed of 46.8 km/h, the TFE Team Edition reduces aerodynamic drag by 2.3%, saving 6.84 watts of power. These advantages are even more evident at 55.8 km/h, where the TFE Team Edition outperforms its predecessor by 2.4 watts, offering more speed with less effort .

The Metron TFE Team Edition is designed to offer a high level of adjustability and customization. With three length options and a wide range of fore/aft and width adjustments, it allows athletes to achieve a customized aerodynamic position. The extended length of the pads and ergonomic shape ensure optimal comfort, reducing fatigue during long-duration events like Kona.
METRON TTW
The Metron TTW disc wheel sets a new standard for speed in triathlon. Based on the Metron 45, this disc wheel with applied fairings and a 21mm rim width offers the ultimate aerodynamic advantage for time trials. Its low weight ensures rapid acceleration, while the sleek design reduces drag, helping athletes slice through the wind with ease.

Rigorous testing at the LSWT wind tunnel in San Diego has confirmed the aerodynamic efficiency of the Metron TTW. Compared to its predecessor, the TTW has reduced drag by 20%, making it the most efficient rear disc in Vision's range. The lenticular profile and PRS hubs, with quick engagement, give athletes a dynamic advantage, ensuring a smoother and faster ride even in strong winds.
The Metron TTW features Vision’s PRS hubs, which offer a 5-degree engagement with 72 points of contact for immediate power transfer. This allows athletes to accelerate faster and maintain speed during critical moments of the race, making the TTW the ultimate choice for time trials.
METRON 91 SL
The Metron 91 SL is designed to handle Kona’s challenging crosswind conditions. With a 90mm deep rim profile and full carbon construction, this wheel minimizes lateral drag while maintaining exceptional aerodynamic efficiency . Engineered using Vision’s CFD protocols, the Metron 91 offers the perfect balance of speed and stability in challenging conditions.


The Metron 91 outperformed leading aero wheels in comparative wind tunnel testing. Across various YAW angles, the Metron 91 demonstrated drag reductions of up to 9.2 watts versus the Metron 81, 5.7 watts versus the M60 , and 3.6 watts versus a direct competitor. These results highlight the wheel’s ability to maintain speed and control even in windy conditions.
The Metron 91 underwent more than 100 CFD simulation revisions to reach its final aerodynamic design. Vision engineers used adaptive computational meshing techniques to refine the rim profile, achieving the lowest possible aerodynamic drag while ensuring optimal stability. This detailed development process, combined with real-world wind tunnel validation, ensures that the Metron 91 delivers superior performance.
