What did I do?

Blorp Blorpmonger /

Tightened my chain a bit because chain kept popping off. Made it too tight because I was going slow. Loosened chain. Still going slow. Noticed these metal flakes on the rear sprocket. What did I fuck up?

You ruined your bearings your races on inside of your hub probably

Re: What did I do?

looks like nuts/bolts for the sprocket have rubbed on something.

wheel not lined up straight? i.e. not pulled straight with the 2 tensioners?

going slow- perhaps something upset with the brake mechanism?

could be jamming on.

Best of luck, Adrian

Take it all apart, clean & inspect the parts for integrity. Make sure on re-assembly they are in the correct order and adjusted properly. Do it before you continue to ride and have even bigger problems.

Sprocket teeth appear to have a very pointy profile, which is a good indication that it may be time for a new chain and sprockets, which may be the source of the metal flakes.

It's NOT comming from the chain but from the brake support

Re: What did I do?

The dust probably isn't coming from the chain , but it still needs to be lubed . That's if the op wants any life out of it and the sprockets .
