Conquers every mountain
-
Optimal suspension performance in any situation
The F.O.L.D. chassis, which has been specially designed to meet the diverse demands placed on it by All-mountain riding, provides a perfectly balanced mix: F.O.L.D. is extremely sensitive while being progressive enough to prevent a harsh bottom out.
-
Lightweight, robust and low-maintenance
High-quality bearings, closed triangle chainstay and a damper protected from dirt – we leave nothing to chance. We have also given thought to the bottle holder.
-
Handling characteristics matter
Since the primary purpose of mountain bikes is to bring pleasure, we have designed the JAM with a modern, agile and aggressive geometry.
