THM's top-line, full-carbon crank with integrated carbon axle and power meter 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 329 g with spider and power meter. Clavicula SE beats all our own benchmarks and is the new reference in crank design.
