THM Carbones Clavicula SE Road Powermeter

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, 293 g with spider. Clavicula SE beats all our own benchmarks and is the new reference in crank design.

 

THM CLAVICULA SE POWERMETER

Clavicula sine exceptione — No rule without exception!

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

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

 

Please note that the delivery time (with PM) is currently around 8-10 weeks

Also aviable with BCD 130 (Standard).
