Weird Crunching noise in rear tire

[GabrielGoes]

Recently i started to hear this crunching noise every time the tire rotates at a certain point, i went over the sprocket, sprocket nut which used to be loose, the chain re-adjusted, but i only hear and feel the knocking or crunching noise on the left side/ on the chain side, what could this be? tires arent rubbing anything eaither..

your chain and sprockets need replacement. this sound is a worn sprocket/chain combo. believe me, I've had it before, on multiple bikes and know WELL the sound of one.

Bad wheel bearing.

Put the bike on the centerstand, grab the top and bottom of the wheel, try rocking it sideways. If it moves at all, it's a bad bearing.
