Clavicula sine exceptione — No rule without exception! Our top-line, full-carbon crank with integrated carbon axle is engineered like no other. In development we 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. We are 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. And, of course, it’s lighter, 293g with spider. Clavicula SE beats all our own benchmarks and is the new reference in crank design.
