Conquers every mountain
-
Optimal suspension performance in any situation
The F.O.L.D. chassis, which has been specially tuned 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.
-
Smooth and fast
Regarding the JAM, NINE stands for 29" wheels. The big wheels impress with smooth riding and traction. They are fast and they can roll over small obstacles easily. Especially this great rollover attribute is outstanding and makes beginners as well as fast riders equally happy.
-
At home on the trail, lightweight and low-maintenance
The JAM 8.9 offers a light carbon frame with sturdy aluminium rear triangle. We leave nothing to chance: high-quality bearings, a closed rear triangle and a damper protected from dirt make your ride carefree. We have also given thought to a bottle cage. And since the primary purpose of mountain bikes is to bring pleasure, we have designed the JAM with a modern, agile and aggressive geometry.
