THM Carbones Crank Clavicula SE Road 2-speed + Chainrings 50 | 34
THM Carbones crank Clavicula SE Road 2-speed 50 | 34 compact
The Clavicula SE is a full carbon crank with integrated carbon axle. During the development special emphasis was placed on an optimal structural design. To emphasize here is the Spider for the Kettenblattaufnahme. It was defined both geometrically and structurally only after analysis of the load paths. An extreme lateral stiffness for optimum shifting behavior and excellent circumferential rigidity for lossless power transmission has been created. Through this optimization, as a side effect, an above-average stiff and lightweight crankshaft system emerged.
THM-Carbones is particularly proud of a patent in the connection of the left crank with the axle . For the first time, a carbon-carbon material combination has been used here, which has been extensively and successfully tested in recent years. It is crucial that the relative movements between the teeth could be minimized here by identical fiber structure of external and internal teeth. As a result, there is practically no wear and no possibility of noise generation at this point. The Clavicula SE significantly shifts the standards set by THM-Carbones. It can be considered as a new reference in cranking.
The cold-forged chainrings from Praxis Works enable precise shifting over a long period of time. The advantage over milled pendants, is the possibility to shape the tooth profile optimally and to make it more durable by the forging process.
The LevaTime chainrings are the product of many years of intensive testing and fine-tuning. The final result is a set of the best and fastest shifting chainrings available.
On LevaTime chainrings, several shift pins are optimally placed in places to provide a perfectly timed shift. Synchronized shift ramps on outer chainrings are matched with a matching inner chainring and allow the chain to switch cleanly upwards.
