Conquers all mountains
-
Optimum suspension performance for every situation
The F.O.L.D. chassis, specially tailored to All-Mountain requirements, ensures a perfectly balanced combination: F.O.L.D. is extremely sensitive while being progressive enough to prevent a harsh bottom out.
-
Light, robust & low-maintenance
High-quality bearing, closed rear triangle and a shock that is protected against mud – we leave nothing to chance. It goes without saying that we also thought to add a bottle cage.
-
It's the ride characteristics that count
We want mountain biking to be a truly joyful experience, which is why we created the JAM with a modern, agile and aggressive geometry.
