THM Carbones Crank Clavicula SE Road BCD 130 2-speed
THM Carbones crank Clavicula SE Road LK 130 2-speed
The Clavicula SE is a full carbon crank with integrated carbon axle. During development, special emphasis was placed on an optimal structural interpretation. Particularly noteworthy is the spider for the chainring. It was defined exclusively by analysis of the load paths both geometrically and structurally. An extreme lateral stiffness for optimum switching behavior and outstanding stiffness in the circumferential direction have resulted for loss-free transmission of force. This optimization resulted, as it were, as a secondary effect, with an above-average stiff and lightweight crank system.
THM Carbones is particularly proud of a patent in connecting the left crank to the axle . For the first time, a material combination carbon carbon is used, which has already been extensively and successfully tested in recent years. The decisive factor is that the relative movements between the teeth could be minimized by identical fiber build-up of external and internal teeth. As a result, there is virtually no wear and no noise development at this location. Clavicula SE significantly shifts the standards set by THM-Carbones. It can be considered as a new reference in crank construction.
