Striving to create a full suspension frame which works as a Marathon/XC bike requires rider studies, engineering studies, as well as longer research and development times than that of a hardtail front suspension bike. Due to the increasing demand from MTB riders for this kind of Marathon/XC bikes, Kyklos completes it’s MTB range frames with the jewel, Flexx. This is the result of direct feedback and specific testing taken with professional riders to develop the Kyklos Flexx. The 4 bar rear linkage system has been well tested and shown to be the most suitable type of suspension system for this Marathon/XC application. It has a remarkable lightness and responsiveness in conjunction with the dedicated geometry and use of XC FOX Pro- Pedal racing shock. Together with this concept of a Marathon/XC bike; Flexx combines new techniques such as Fit BB press 92. The steering headtube is 1”1/8 to 1”1/2, external cables, just like the hybrid concept stone.
