Thun’s upgraded composite parts in a league of its own

Thun is now lifting its bb-sets’ composite parts to a new level of excellency. This comes after advocating composite cups and sleeves for decades – particularly in view of the disadvantages associated with steel cups.

Now, all composite parts are upgraded in terms of the material that they are composed of. Within its corporate language Thun refers to the new material as “Composite A”, while the actual name of the new composite remains confidential so that the competitive advantage is protected.

The new material, which technically is a so-called RM-material (RM stands for reduced moisture), makes Thun’s composite parts even more resistant to climate related changes in terms of temperature and humidity. Since bb-sets produced by the German manufacturer and self-proclaimed global market leader are specified by OEMs around the world, Thun’s objective is to adapt its products to the regional needs of different markets.

Also, Composite A withstands ultra-high assembly torques which makes the assembly of Thun bb-sets more fool-proof than ever. Still, Thun recommends sticking to the assembly torques mentioned in the respective assembly instructions for best results. Moreover, the material does not require any changes of assembly processes at the bicycle manufacturers’ assembly lines.
