I mounted my fixed gear bike and I would like your opinion about the installation of my chain.

The noise in the following video is made by my chain (and nothing else) and I am not reassured. I first thought the run of the chain was not correct but yet it seems it does. I checked that my chain can move vertically more than +/- 0.5 inch (halfway).

Here are my components (they are all new):

Here is the video, how does it sound ?

  • What's the cog? – Nathan Knutson Mar 30 at 6:35
  • @NathanKnutson : I don't have the precise model, it's a used cog that I bought in a shop. It's in steel and has 19t. Do you think it could lead do a misalignement of the chain ? How can I check that the tooth are still good ? – Smilia Mar 30 at 11:34

At first I thought the chain was rubbing on the wheel, if its a new chain then it might not have been greased. Don't use wd40 if its not greased, it will wear it faster. Try White Lightning.

Have you checked your chain line? Sometimes if your chain line is off you can hear the inside of the chain links rubbing a bit too much against the teeth on the cog and the chain ring.
