Chains for fixed gear bike noise problem 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):

Surly steamroller frame
chain 1/2 x 1/8
miche Bottom bracket 107mm
miche primato adavanced drive

Here is the video, how does it sound ?
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.
