integrated skeleton concept

-
The skeleton concept iSC (integrated Skeleton Concept) has been around since the first legendary promachine. Since then, the concept has spent over a decade being refined and redefined. The idea is saving weight by supporting the top tube at the seat tube and increasing the stiffness where it is needed. In the front triangle of the frame. With the help of the latest in FEM (Finite Elements Method) computer technology, we can tailor each tube junction perfectly to the distribution of forces. Cleverly selected skeletal reinforcement elements at the nodal points and the spread of the top tube distribute the impacting forces perfectly and result in BMC's typical crosslock. distribute the impacting forces perfectly.
