The “Clavicula” is a revolutionary new design of an all-carbon crank.

New production methods, never before used for cranks, result in a giant leap in total stiffness. The crank’s stiffness-to-weight ratio sets new standards.

The sealed bearing bottom bracket attaches outside of the frame using the standard BSA threads. This design allows the use of larger diameter bearings and a wider bearing placement. In combination with the 30 mm diameter axle these modifications make for a very stiff drivetrain.
