Is it worn my guys? Or still some life in it? Gears are shifting a bit rough and it feels a bit crunchy turning the cranks.

It’s fine, needs a bath and lubing though
Yes
Yes. The little tab should not fit into the chain at all. If it feels crunchy, and you think it’s the chain, I would swap the chain. What’s that, a $20 fix?
Yes, and since .75 goes in, you likely need a new cassette as well. Change the chain earlier and save the expense of a new cassette.
Crunchiness could easily be from dirty chain. According to your photo, your chain has not reached .75% wear, however, chain wear is measured for a clean chain as dirt, especially hard and abrasive particles mask chain wear
Can somebody explain to me how to read these things?
IIRC the fancy 10+ speed ones were done at .75, while <8 speed could go to 1%, but in that case you had to replace chain AND cogs.
Drops down, no go, still hanging even just little bit, good to go.
I swap the chain when it’s at 0.40.
Kmc reccomend to swap the chain within 0.40-0.80
0.80 will be horrible.
At 0.40 straight away I feel a difference once I swap to a new chain.
At 0.40 and below, chain is not worn out yet.
As yours gets in, but not all the way in it’s half way to the max, so it’s not a crisis yet, but should replace it soon
Well it depends on how many gears you have. 0.75 is a new chain in all cases but if you are on a 6-9 speed cassette it can be fine. Check if the teeth are sharp and pointy on the cassette. If the new chain skips or doesn’t feel smooth change the cassette as well. It’s not a huge job you just need the right tools
Thanks everyone! I’ll give it a proper clean first and go from there.
1x setup done, 2×11 still fine if the other side doesn’t slip in
How many miles, and what type of riding?
I got kinda obsessed with original Ebike chain rivets being flush to link at 2200 miles. Not shifting smoothly even after adjustment. Yes, it needed replacement. Changed brake pads too, original at 900 miles 75% wear. second set at 2200 showing 50% wear. End of 2025 season tuneup. My LBS is transitioning to ski season. Seattle area.
If you have an 11 speed cassette replace the chain. If it is a 3 speed your okay.
Just about
Need to check it when it’s clean, but it looks okay in this.
I’d replace it. You’re probably at .65. Chains don’t cost much; they’re far cheaper than replacing your cassette.
Depends what speed chain you have single speed
how many speeds is your drivetrain? the recommendation I’ve heard is to replace chains at 0.75% for 8-10s, and replace at 0.5% for 11-12s and lg, in order to minimise ware on other components.
That prob is 0.5 and depending on how expensive the rest of your components are, it could be time to change in that case..
..its junk or soon to be ..
get rid of it
Change it bro!
I replace chain at .5 with the opposite side. Otherwise you’re buying a cassette also. Change the chain and see how it rides. If it’s good you’re good , if crunchy you need a new cassette also.
And what about lateral stretch?
Use a ruler, measure from pin to pin 12″ is new, 12 1/16″ ok, 12 1/8″ replace, more than 12 1/8″ mean you probably need a new ring as well.
The problem with chain checker tools is they only measure 3 or 4 inches, so , 1/16″ over 12″ equals around 1/ 64″ over 4 inches, thats so small as to be easily manipulated by slight movement
I highly recommend getting a parktool chain checker and clean the chain. I had the same tool you are using with roughly the same measurement. I was about to replace my chain but decided to check with the parktool first. Parktool showed less than 0.5 wear.
yea
Yes you need a new cassette chain and chain ring.
Measure in multiple places and take the worst measurement as your indicator for replacing the chain.
