Redefining the boundaries of speed. Is it possible?
A synergistic challenge, months of incredibly intense work, a joint project orchestrated by our Innovation Lab together with Stefan Küng and all the staff of the Groupama - FDJ Performance Center.

The aim 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.
* Data collected in wind tunnel from comparative tests (Supersonica SLR vs Turbine SLR) with wind at 50km/h and a turbulence factor of 0.3%.

R&D
2 prototypes built, dozens of kilograms of 3D printing, over 50 hours of computer simulations, 30 hours spent between the wind tunnel at Silverstone (UK), the velodrome in Switzerland and road tests in Belgium. These figures emphasize how much dedication lies behind such a high performing and demanding product.
A technological revolution
Supersonica SLR however is much more than just the best time trial bike we’ve ever built. Supersonica SLR constitutes a veritable technological revolution that today represents the pinnacle of our innovative ability and demonstrates how valuable it is to work with some of the world's most experienced and powerful athletes.
Custom aero extensions
You'll be able to customise your Supersonica SLR aerodynamic extensions with optical forearm scanning and subsequent production, with a choice of 3D printed titanium or premium quality carbon laminate.
