The chain ring is one of the central drive components of your bike. It is the direct connection to your bottom bracket and ensures that your chain or belt moves smoothly. Due to the constant loads when riding, the chain ring is one of the wearing parts on your bike that you should check frequently and replace if necessary. You can find the right spare part at CONTEC!
