Hi,

I need a hand.
My bike has started making a nasty grinding noise.
When i have my lid on, it sounds like the gear box, but going up and down my road with no lid, its definitely coming from the rear sprocket/chain.

Its making a rattly grinding noise, my chain was mega loose..

Tightened it up, its still there, if i flick my chain it makes a little chinking noise which i assume is normal.
But the grinding when i move surely cant be, well i know its not right.

Help please.


Andy
