THM Clavicula SE Road Carbon Cranks | 160-175mm, from 293g

Full carbon crank with integrated carbon axle  |  293g with spider (Compact)  |  Patented carbon-to-carbon axle interface  |  Now available in 160 and 165mm, up to 175mm.

Clavicula SE is THM's top of the line full carbon crank, built with an integrated carbon axle and a geometry defined by precise load path analysis.

The result is extraordinary stiffness in every plane for loss-free power transmission. THM is particularly proud of the patented carbon-to-carbon interface between the left hand crank and axle, the first successfully productionized carbon-to-carbon connection at the heart of a drivetrain.

Aligning the fibers of the external and internal splines cuts wear to near zero and eliminates noise at that joint. It's lighter too, at 293g with spider for the Compact system, making Clavicula SE THM's new reference in crank design.
