For a noise reduction it is made of nylon. For this reason, it is more vulnerabile if excessive forces act and at the same time no crank movement takes place (brake, wrong gear, etc.).
The gear should be sufficiently greased with Mobilgrease 28 (as well as at regular intervals - see our blog post).
