PSA: I just learned that a properly tensioned chain should only deflect about half an inch, not a full inch
Read it in an old Park Tool manual I found at a garage sale for a dollar. Has anyone else been over-tensioning for years without realizing it?

Yeah, that "half an inch" thing is what my local bike shop guy always says. He told me a super tight chain puts extra stress on the whole drivetrain, not just the chain itself. It can wear out your rear hub bearings faster because everything is under so much pressure. I used to crank mine down until it felt solid, but I was definitely wrong. Makes you wonder what other basic maintenance steps we've all been getting wrong for years.
