Upgrade / F.O.L.D. GEN2
The second generation FOCUS Optimised Linkage Design is more progressive than the previous F.O.L.D. linkage design, so that the puncture protection at the end of the suspension travel is even stronger – for more stability in demanding terrain. This is made possible by a change to the guide and Mainlink lever. However, you will still experience the chassis as sensitive. Another advantage is the lower standover height of the frame made possible by the F.O.L.D. upgrade.

C.I.S.
Fully-integrated C.I.S. cable routing ensures a tidy cockpit. All cables run through the special stem and headset directly into the frame. Perfect braking and shifting is guaranteed at all times.
