THM Clavicula SE Crankarm with PowerMeter

Clavicula sine exceptione — No rule withoutexception! Our top-line, full-carbon crank with integrated carbon axle isengineered like no other. In development we focused on optimizing itsgeometrical and structural definition, based on a precise analysis of loadpaths.

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

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

THM CLAVICULA SE POWERMETER

Clavicula sine exceptione — No rule withoutexception!

Our top-line, full-carbon crank is thebenchmark for lightweight crank sets for years. With adding strain gauges and asmall light electronic module in the axle, powered by a lightweightrechargeable li-ion battery, we achieved to keep the additional weight for thepowermeter feature for our Clavicula SE under 27 g. Furthermore you are free toride your desired lightweight pedals.

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