Was looking at my sprocket (after riding in wet areas) noticed that water ect. is able to pass the fasteners holding the sprocket on(trickle of colored mud after washing coming from all fasteners) I checked to see if they were loose and they spun freely in the hole put the nuts were secure.....is this oh crap or you just now noticed this(like the full floating rear brake making noise) or maybe both?
Take them off and check the holes in the hub for elongation. Hopefully this has not yet occurred! Clean the threads, I like medium locktight, red is too tough, put it back to together and check them every couple rides so you'll know if they are loosening.
Are you running an aftermarket sprocket? I've heard of some countersinking to be too deep and the nut running out of threads when you tighten.
