Check the easy stuff first, chain tension and lube, sprockets tight, brakes not binding, etc. Does it squeak with each wheel rotation?
not every rotation, more of an intermitent squeek with some weird very faint "popping" I will put it on a stand (milk crate) and rotate the wheel by hand to get a closer look. Im sure I will pinpoint exactly what it is then. I will post back with results. thanks
