JAM 8.9

Geometry Specification

Makes the mountains your playground

  • Optimized kinematics for strong progression

    With the upgrade of our well-known F.O.L.D. kinematics, your JAM is ready to shred even more. We kept the well-liked sensitivity of the F.O.L.D. but changed the positioning of our kinematics within the frame for strong bottom-out resistance. The characteristics are completely progressive which results in a chassis that offers a lot of stability in rough terrain. This allows you to handle any trail while the chassis still provides comfort for long laps. Furthermore, the lower standover of the JAM gives you more space to play on the trail.

  • For your inner child

    The JAM is made for your inner child: Playful and intuitive you get the most fun out of every ride. The geometry is well-balanced for your rides in tough terrain: An agile handling merges with a lot of safety resources of the chassis providing confidence in rough downhills. You are perfectly-seated in the middle of the lightweight carbon bikes to be in control of any situation and to easily pedal up all the steep hills on your ride. The FLIP CHIP at your JAM's linkage can be used to adjust your geometry to an even more aggressive riding style. The small adjustment of the head angle from 65,5° to 65° changes your whole set-up making it even more downhill-oriented.

  • Integrated and lightweight

    It's all about the details: In the down tube of the lightweight carbon bike, you can store your essentials thanks to our I.C.S. (Internal Compartment Solution) technology. One easy click and a cover on the down tube opens up. Within the down tube, your equipment fits in the integrated tool bag that you can easily take out if necessary. Furthermore, the specially developed C.I.S. (Cockpit Integration Solution) design ensures a clean cockpit and constantly seamless shifting and braking. All cables run from the handlebar into the stem and through the headset into the frame.
