what is this creaking sound?
when exert any force on my bike, i.e. up hill riding or standing up while pedaling, i get this creaking sound. the more force the more it turns to an almost popping sound. everything's tight. everything's got lube. i was just sitting outside holding the wall and rocking back and forth slowly on it while applying only minimal pressure to the pedals and it mad this sad little 'grandma in her rocking chair' kinda sound. i know that my options are basically the pedals, the cranks or the bottom bracket. so is there any way to narrow it down and figure out which one it is? or are there other options for creakiness?
