Wear and tear



The CBD timing belt drive system stands out because of its low belt pre-tension and easy handling; however, even these characteristics cannot fully exclude the possibility of wear and tear relating to age and intensity of use.
 
  • Check the timing belt and the sprockets for defects before every use. Using a worn-out or damaged component can result in injury or damage to the CBD.
  • If you notice any wear and tear on the timing belt and/or sprockets, find a bicycle retailer who can check the condition of the timing belt drive system and replace the worn parts if necessary.
  • The following overview gives specific examples of wear and tear and the corresponding actions to take.
