Light and stiff frame building with iSC
( integrated Skeleton Concept )
For the ambitious cyclist who attaches great importance to direct handling, good propulsion and the best possible
efficiency. Thanks to the use of the highest quality carbon materials – with the function-specific application of highly rigid and high-strength fibers – BMC develops a very light, performance- oriented iSC carbon frame.

With a neat combination of different carbon fibers and their alignment, and by applying stepped tube profiles, we achieve increased vertical compliance while maintaining high levels of lateral and torsional stiffness.
Tube junctions perfectly tailored 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.
Tapered head tube - with a minimum increase in weight, a disproportionately higher fork thickness results.
