Wilier Triestina Supersonica SLR frame 2026

Redefining the boundaries of speed. Is it possible?

A synergistic challenge, months of incredibly intense work, a collaborative project orchestrated by our Innovation Lab together with Stefan Küng and the entire staff of the Groupama-FDJ Performance Center.

The goal of the project?
Simple: to improve the aerodynamic performance of our time trial bikes by at least 10%. The result? Supersonica SLR: the new time trial and triathlon frame that improves aerodynamic efficiency by almost 16% compared to our previous time trial frame.

Research and development
Two prototypes built, dozens of kilograms of 3D printing, over 50 hours of computer simulation, 30 hours spent in the wind tunnel at Silverstone (UK), the velodrome in Switzerland, and on the road in Belgium. These numbers underscore the dedication behind such a high-performance and demanding product.

A technological revolution
However, the Supersonica SLR goes far beyond being the best time trial bike we have ever built. The Supersonica SLR has been a true technological revolution, which today embodies the pinnacle of our innovative capabilities and demonstrates how valuable it is to collaborate with some of the strongest and most experienced athletes in the world.
