My chain looks flabby when on the smaller sprocket.
Not sure it was like this before. You can see the picture.
From the second sprocket and up, the chain get straight.
I don't have a tool to check the chain wear.
But used the 12" trick, and have 305.5mm instead of the planned 304.8mm.
Should I remove one link? Or tighten something on the derailleur?
