The clavicle SE is a full-carbon crankset with integrated Carbon axle. In the development, special emphasis was placed on optimal structural design. Special mention should be the Spider for sprocket carrier. It has been defined both geometrically and structurally only by analysis of load paths. Here an extreme lateral rigidity for optimal switching performance and excellent rigidity in the circumferential direction for lossless power transmission originated. This optimization was, so to speak, as a side effect, an exceptionally stiff and lightweight crank overall system.
Is especially proud of THM-Carbones on a patent for the compound of the left crank to the axle. For the first time here is a combination of materials Carbon-carbon is used, which have been tested very extensively and successfully in recent years. What matters is that here the relative movements could be minimized between the teeth through identical fiber construction of external and internal gearing. The result is that there is virtually no wear and no possibility of noise at this point. With the clavicle SE permitted by THM-Carbones standards are significantly shifted. It can be considered as a new reference at the Kurbelbau.
