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)

probably the chainring being bent (if you are having a rhythmic side to side movement of the chain).

if the chain is tight and slack, when the drivetrain is moving then it means the chainring is not centered on the crank.

Have you made sure the chainring bolts are tight?

Is this a conversion? You might need a new BB with a different spindle length.

he said it wobbles when spinning. incorrect BB length would not cause that.

(come on and use your brain!)

yes my bike is a conversion, and when the bike is spinning the chain moves out of its place, looks wavy. the top and bottom chain isnt parallel with each other when spinning.
