I tried searching but couldn't find any luck, please forgive the n00bness.
In a nutshell, with one pedal in the down position the chain is snug and good, though 180* later with that same pedal now up, the chain is much looser. I have not noticed the issue before but I cannot get the chain on tight and snug without making it too tight for part, or part of it is tight and the other half of the pedal is loose.
Is my rear wheel not true, bent, chain messed up, crankset (brand new), etc?
Thanks in advance.
