Concept
Geometry and component specification are carefully selected so that the alpenchallenge can be ridden almost anywhere. The position is comfortable enough for long rides and the gearing chosen to help conquer the steepest climbs. The frame accepts a wide range of accessories, as well as being compatible with all three wheel sizes common on modern bicycles.
Reliability
Not having to constantly adjust and maintain your bike helps you enjoy more time riding, and spend less of it in the workshop or stopped by the side of the road. Our frame uses proven technical solutions, and we build it with dependable yet light parts such as fast-rolling tires and wheels with Shimano drive trains and brakes.

iSC
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.
triple butted

Triple-butted tube set made of a 6000 alloy. Triple-butted means that the tube has three different wall thicknesses.
