Ka-CHUNK! Again with the chain noise. But it can mean so many things. Sometimes it's a tight link, which we covered last time. But when you go in to investigate, you may not see the telltale stiff link. That may be because your chain got twisted during the ka- CHUNK. A twisted link is easiest to spot by looking lengthwise down the chain, and it's almost always the narrow link. When you find it, fold the chain 180 degrees with that twisted link at the apex. Use the lengths of chain in each hand for leverage to twist the link back straight. Look lengthwise down the chain again, and you can check your work. As long as it wasn't too severe, you can still trust the chain, but check your shifting to see what caused the harsh shift.
