Your rear sprocket looks serviceable as well. Cleanliness apparently reaps benefits.
Your technique looks more precise than how the manual recommends pulling of a single link away from sprocket and estimating deflection.
Tony is so involved with his never ending chain saga that he actually gave me an o-ring chain from his supplies.
Thank you Tony!
This is the very chain that ended up being installed on plumbstraights bike here when we geared him up (down?) for my "easy trails" with a 55 tooth rear sprocket. So Randall, your chain comes with an interesting somewhat convoluted pedigree.
And Tony your generosity keeps reaping benefits.
How old and how many miles on that chain? It looks as supple as one of Randall's Hickory shirts.
