Hi all.

Went on a weekend trip recently & on our way back the bike started making a very strange noise coming from the front sprocket area.
It almost sounds like the chain is running at an angle... a strange grinding sound.
I've checked tensoin, lube, etc.
The copper-like "guide" on the inside of the front sprocket cover is slightly (very slightly grinded)
Any suggestions of what it could be or what else I can take a look at?

is your rear wheel running straight or your sproket not damage rear one?

If you are happy that the chain is ok and both sprockets are secure and also ok - loosen the chain off and check for play in the drive shaft bearing by grabbing the drive sprocket and focing it up/down and side to side.
