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 drivetrain.

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

THM CLAVICULA SE Powermeter

By adding strain gauges and a small electronic module in the axle, powered by a lightweight rechargeable li-ion battery, we managed to keep the additional weight for the powermeter feature of our Clavicula SE under 27 g. Furthermore, you are free to ride your desired lightweight pedals.

In total, this leads to the lightest powermeter on the market with only 320 g for the compact and 329 g for the standard.

Also available with BCD 130 (Standard).
