THM-CARBONES CLAVICULA SE

£1236 - £1344 (scroll down to configure this product)
Clavicula sine exceptione! No rule without exception! Our flagship 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 productionise 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 at 293 grams! Clavicula SE beats all our own benchmarks and is the new reference in crank design.
