The engineers at SCOTT spent a lot of time analyzing the compliance characteristics of bike frames as well as finding unique solutions that match the engineering philosophy of the Carbon experts in Switzerland. As shown in the 3D drawings below, the joint between the seatpost, toptube, seattube and seatstays is the most crucial point when a frame is examined with regards to comfort. Based on this finding, the engineers analyzed and tested different solutions with regards to tube shapes, the Carbon lay-up and the attachment of the seatstays. Resulting from this analytical work, the engineers came up with a unique frame design in the most critical area for compliance of the rear triangle. They decided to attach the seatstays directly to the toptube, considerably improving comfort without compromising headtube torsional stiffness.
In addition, the engineers intentionally left out the traditional bridge between the seatstays required to mount the rear brake to make sure that the comfort through seatsay deflection is not compromised. Optimizing comfort at the front of the frame proved to be no lesser challenge for the engineers. In order to provide a comfortable riding sensation, the fork needs to give in to vibrations arising from the ground while at the same time needing to resist forces that arise from braking. The top area of the fork, including the Carbon steerer and the crown has to be rigid for direct handling and safe braking. To determine the right balance between comfort-increasing deformation and stiffness for braking efficiency, different Carbon lay-ups were developed and tested before a decision for the final version of the fork was made.
