Pro tip: I thought the Park Tool chain checker was overkill for a home bench, but 3 worn chains say otherwise
I laughed at a buddy in Dayton who told me to stop guessing with a ruler and just buy one, but seeing my commuter chain hit 0.75 percent at 1,800 miles sold me. Now I'm curious how often you all check yours, every other month or just when shifting starts to feel off?
Checking at 1800 miles on a commuter is smart since those miles add up fast in all kinds of weather. Also look at the chain rings and cassette, because a worn chain wears those down too and a new chain on old gears will skip. Keep a log of miles so you know when to check instead of guessing.
