Hey all, I posted this question over in the PB mechanics thread but thought I'd throw it on here too.
So I was selling a used bike and I measured the chain the way I learned to do it decades ago with a ruler. I got 3/32 of stretch in a foot. The guideline I was taught years ago back when I worked in shops was under an 1/8 you could put a new chain on and it would work fine with existing cassette.
The guy buying the bike asked if he could have a shop look it over, the mechanic measured it with his little Park measuring tool and said it would need a new chain and cassette which would be $150 with labor.
I bought a chain from them and put it on and did the "pedal hard in the small cogs" test and got no slippage.
So I guess this is kind of a poll, what is everyone's policy for cassette replacement? The shops I worked at always gave the customer the option of trying just a chain if it was within that 1/16 to 1/8 window, are my methods antiquated?
Thanks for your responses

The xo1 11 cassette on my other bike won’t be replaced till it fails. Don’t got the money and something cheaper adds a lot of weight that I think is more of a hinderence than the occasional slow shift and a bit of noise. I imagine with 12 speed this would only be more true.
