Technological benefits

Theoreme FS 100

Theoreme FS 100

For racers in search of victory, predictability, and performance. The 100mm travel version is for you. Lightweight and aggressive, this is the version that will let you smash your PB's, whether it's a local race or a World Cup.
Dynamic Linkage

Dynamic Linkage

When developing the Théorème FS, we made suspension performance our number one criterion. We considered all the parameters and effects of full-suspension to reach our final choice. We required a system that was light, and highly efficient in tough technical sections, and that gave the sharpest handling. The solution was evident:
A Flex Pivot system, in other words, a deformable parallelogram, where the rear pivot point is provided by the deformation of the seat stays. Following on from Dynamic Response on our road bikes, discover Dynamic Linkage on our mountain bikes.
Integration

Integration

We’ve gone for maximum integration. If integration is more associated with road bikes, we wanted to better protect all the cables by placing them inside the frame. We wanted to eliminate as much as possible all the white noise when riding. Riding the Théorème FS, you will only hear your breathing and the tyres crunching along the trail.
Integrated lock

Integrated lock

Why limit ourselves to integration when we can develop an entirely new headtube?
A revolutionary head tube. Why limit ourselves to integration when we can develop a completely new head tube Thanks to an integrated lock developed by our engineers, we've limited the steering angle to 72°.
Full UDH compatibility

Full UDH compatibility

From the very beginning of the development of the Théorème FS, we designed it to adapt to the latest standards.
The UDH universal derailleur hanger, lets you inexpensively protect your frame. This format is also compatible with direct-mount derailleurs, with no hanger. With the new Théorème FS you can access all the new standards in MTB bikes.
