    contrary to picture chainrings are not included
    The “Clavicula” is a revolutionary new design of an all-carbon crank. They are designed in close cooperation with the Cologne-based design-specialist formagic.

    New production methods, never before used for cranks, achieve a giant leap in total stiffness. The crank’s stiffness-to-weight ratio is setting new standards. In-house lab testing of various high-end cranks shows the superior performance of our crank system.

    The cranks are designed for road bike applications with a 130 mm or 110 mm bolt circle diameter and for 68 mm bottom bracket width. 170mm, 172.5 mm and 175 mm crank arms available. Very large, sealed bearings allow the use of a 30mm axle. This ensures high stiffness paired with low weight. We have developed bottom brackets for all common BB-standarts, so the Clavicula crankset can be adapted to virtually any frameset available.

    Extensive testing of this ground-breaking invention was our top priority. We are currently undertaking various long term and stress tests, because as a pure-bred racing component the “Clavicula” must be able to continually withstand highest loads – be it in hard sprints or during the toughest classics.

    Both static and dynamic tests have been completed successfully. However, to aviod even the slightest risk we are currently setting a permissible total weight limit of 105 kg (231 lbs.). Your safety is our main priority!

      I received my first Clavicula about one year ago. I've ridden about 4000 kilometers with the thm carbon cranks. Now, the carbon fibre is cracked. I sent the cranks back to THM, they said that they will repair the failure. Nice support :-) .... Apart from this "accident" : Awesome cranks!!!!

  • THM Carbones has been awarded with the German seal of quality by federal research organization.

    Since 20 years THM Faserverbund-Technologie GmbH explores the best possible approaches in case to engineer high-performance and state-of-the-art components.

    The exact direction of the carbon fibre along the force flow leads to an optimal use of the material's potential. Hereby THM Carbones has been inspired by the structure of natural bones in case to reach maximum performance in comnbination with least weight of the particular components.

    Finally THM achieved being honored with the German "Innovativ durch Forschung" award.
