Intransigence respective light weight and rigidity – thats one of the cachets of the germany company THM-Carbones. There are 3 famous products of them: Clavicula cranks, Scapula roadbike fork (Scapula Review) and Fibula rim brake, All of them share the same features: they are really lightweight and enormous stable.
THM realized this thorugh the ingenious use of carbon fiber. Carbon bikeparts allow really low weights combined with an extraordinary firmness (in relation to the weight).
Below, I will explain some issues concerning the Clavicula cranks.
The Clavicula was primarily designed for the use with a roadbike – but today, there is also a version available which is compatible with mountainbikes. The optimal use for this high-end bicycle component are time races and triathlons.
THM successfully completed many tests which were checking the stiffness of the Clavicula ( -> test reports).
With only about 420 grams total weight, you will beat your competitors.
But this performance isn’t a cheap thing – you have to pay about 900 Euros for this bike part.
And you have to pay attention while mounting this crankset. Like all other carbon-made bicycle parts, you strictly have to follow the stipulated torques! If you are applying this component with more power as required, you can damage or destroy it!
Furthermore, it’s quite important that you make a allround-check concerning the integrity. Before every cycling tour!
Carbon bike parts are sensitive and – even the smallest – harms are leading to a serious lack of security while driving!
Of course, there are many other carbon cranks available on the market.
