|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!
