Chain has begun to rattle: problem?

Hi folks,

My friend borrowed my fixed-gear bike and decided that my chain was too loose for his taste. He pulled the wheel as far back in the dropouts as he could and cinched it down. A few days later I noticed that when I tap the chain it makes a little rattle noise as if something has changed. The chain looks like it's in decent shape but I have not checked for stretch. Do you guys think I have a damaged chain?

Chains are pretty tough. I'd set it up correctly and see how it rides, then see if further investigation is warranted.

What has changed is the lubricant is drying up.

Dry, or wax-type lubes are particularly rattly after just a couple of rides.


A more-substantial lubricant will cure this, and it has nothing to do with the chain adjustment beyond the fact that the vibrational frequency of the chain varies with tension.
