Clavicula SE Road Compact and Standard

Clavicula SE is the ultimate innovation from the company THM-Carbones. In the development phase particular emphasis was placed on optimizing structural design. Particularly noteworthy is the spider whose geometrical and structural definition is based on a precise analysis of the load paths – with the result of an extreme lateral stiffness for best switching behavior and an excellent stiffness in the circumferential direction for loss-free power transmission. This design optimization resulted – just as a side effect – in an exceptionally stiff and light crank system.

We are particularly proud of the patented connection 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 the 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.

With Clavicula sine exceptione the company THM-Carbones is setting completely new standards and will make you experience a new reference in the design of cranks.

For the initial use on racing bikes are made available chain rings with 130 mm or 110 mm diameter bolt circle. As a matter of course all current bottom bracket systems are usable which means the Clavicula SE will practically fit any type of frame.
