THM Clavicula SE Carbon Crankset

THM's top-line, full-carbon crank with integrated carbon axle is engineered like no other. In development THM focused on optimizing its geometrical and structural definition, based on a precise analysis of load paths.

As a result, it is extraordinarily stiff in all planes, exactly what’s required for loss-free power transmission. THM is particularly proud of the patented connection between left-hand crank and axle — THM is the first to successfully productionize a carbon-to-carbon interface at the heart of the bicycle drive train.

Aligning the fibers of the external and internal splines reduces wear to near zero and eliminates noise. Of course, it’s lighter as well, and astonishing 293 g with spider. Clavicula SE beats all our own benchmarks and is the new reference in crank design.
