Hi, Quick question about using a chain wear tool as per my images – would the tool have to "fall down" in between links to indicate 0.75% chain wear? it's currently at an angle and I'm not able to push it down any further.
I've already ordered a park tool one due to be delivered in couple of days but would like to ride my bike this weekend.
Thank you

When the tool slips down between links, it’s 0.75% worn, and should be changed immediately. (Though on 11 or 12 speed systems, many would say they should be changed around 0.50%.) If the 1.0 side drops between the links, the chain is well and truly knackered – so much so that you’re probably damaging your cassette. Your chain has plenty of life in it. Enjoy your ride!
