Note: The crank with 130BCD will be delivered, instead of the 110BCD version shown. Delivery includes the crank with integrated axle only. Other products shown like chain rings and bolts serve solely illustrative purposes and will not be delivered.
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 anexcellent 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.
THM is particularly proud of the patented connection between left-hand crank and axle. It’s the first time that acarbon & 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.
Indeed the Clavicula SE has passed the first stress test with flying colours, setting new standards with an excellent stiffness to weight ratio. This result shows that THM-Carbones adhere steadfast to their philosophy of offering products meeting the highest quality standards only. Clavicula sine exceptione – Clavicula without limitation.
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.
