Carbon fiber crank Clavicula M³

Clavicula M³ is a modular full carbon crank with interchangeable carbon spider. By changing the crank-spider it can be used either with a standard bolt diameter (130mm) or a compact (110mm) variant. Clavicula M³ is also available with the SRM power meter – just change the spider and you´ve got the lightest SRM crank in the world.
All common BB-standards can be adapted, this still holds true with our newest addition to the Clavicula family. It goes without saying that it is light – 325 g without spider – including the SRM system only 740g!!! – less than many other cranks without power measurement.
