Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

not enough grease on your BB threads, or it could be a chainring bolt. Or it could be coming from your seat and sounding like it's from the BB area.

How is your chain tension? Sounds like it could be too tight or maybe just a tight spot.

yeah, if it's not gremlins and if regular grease doesn't work, try some anti-seize compound or a little loctite.

Or it can be chain alignment, that is the most probable cause of your noise.

What kind of metal against metal sound? Is it a rattling? A squeaking? A grinding?

Have had a similar experience ever since adjusting the chain tension. I've been hear/feeling a slight knocking coming from the cranks. Checked out the ring, the chain seems to be in line, but seems a little "off" in one spot...how to correct this?

It sounds like your chainring might be bent. Pull it off and put it on a flat table or a priece of glass or something. If it's bent at all, it will cause a wobbling and there for cause your chainline to be off a bit each revolution.

it sounds like when a bike has a front deraileur and the chain is slightly rubbing against it. i figured chainline was the cause and i checked all that crap right away and it seems fine. i'll just tinker with it and eventually the noise will go away.
