Clavicula SE is a full carbon crank with integrated carbon axle. In the development phase particular emphasis was placed on optimizing struct ural design. Particularly noteworthy is the spider whose geometrical and structural definit ion is based on a precise analysis of the load paths – with the result of an extreme late ral stiffness for best switching behavior and an excellent stiffness in the circumferential d irection for loss-free power transmission.

This design optimization resulted – j ust as a side effect – in an exceptionally stiff and light crank system. We are particularly proud of the patented connectio n between left-hand crank and axle. It's the first time that a carbon & carbon material combination is realized which was tested thoroughly and successfully in the last few years.

Decisive advantage: This solution minimizes the relative movement between th e teeth thanks to the identical fiber texture of the external and internal toothing. As a result wear-and-tear is practically zero and there is no source of noise development. Clavicula SE clearly outshines all benchmarks so fa r set by ourselves. Indeed it can be considered as a new reference in crank design. Clavicula sine exceptione – without limitation – is synonymous with a new kind of smoothness and outstanding utilization of load path s. A highly promising forerunner for the next technologically oriented development step to come.
