(solved -> not chain related)

KMCx10e a couple of times, not only on my bike but on others. I get the chain and put it on with the same number of links as previously. It's the exact same model chain as the old version and I use the new missing link provided with it. When I pair the chain with a Shimano cassette (HG50)

I did have brand new KMC X10e + Shimano Deore 10S cassette.
Since both were new, within 20 miles, everything bedded in correctly and it was a silent, crisp shifting.

replacing only one of them while the other is worn is not the best case.

I changed both the cassette and chain at the same time. Maybe I’ll try the Deore instead of the HG5xx series.

Are you sure its skipping at the cassette and not the front chainring.

The skipping your describing is what has always happened to me if I wait too long in replacing a chain (happens with different chain speeds/brands/models). Sometimes it skips at the cassette and sometimes at the front chainrings (and sometimes both).

I usually start thinking about replacing chains at 1k miles, I consider myself lucky if I can get to 2k miles. I measure chain stretch about every 4 rides.

If you can, post a pic of your front chainring where the skipping occurs.

I use the Shimanp TL-CN42 chain checker (most accurate way to measure chain stretch other than measuring with a ruler). Alot cheaper than cassettes and chainrings.

Maybe I’ll go all Shimano.

That's exactly what I did on my BULLS.

I have had very good experience with Shimano products so far.

Bulls seems to use KMC pretty exclusively. I didnt check all models but everything in the Bulls "eMTB' and 'eMTB Fully' used KMC chains (KMCx10e or KMCx11e). They also use Shimano HG50 or HG500 cassettes amongst others.

I replaced the KMCx11e chain(with a KMCx11e) on my Bulls Evo 3 27.5+(Shimano Deore SLX CS-7000-11, 11-42T cassette) at 2500miles because Shimano TL-CN42 tool said it was time. I usually just measure with a ruler(although I have a few park tools which I consider useless) but the shimano tool is so quick and effortless to use. No chain skipping whatsover. I was actually surprised as even when measuring with a ruler I sometimes would get skipping at which point I would replace the chainrings and cassette and no more skipping. That being said after a chain replacement or two you might need to change cassette and/or chainrings anyways.

I was going to put an HG50 11-36 cassette on my iZip Moda anyways with a new KMCX10e chain. Ill report back on the results but I dont perceive there being any issues.

Perhaps you know all this but Ill post anyways for others following this thread. I post this because when I was replacing the new chainring(from 48t to 42) on my iZip Moda, I was curious as to the cassette engagement and it seemed all wrong applying 'common sense', these links/videos showed it was fine.

IMHO, chains are cheap(and super easy to replace), chainrings and cassettes not so much. 9000km on a chain is pretty excessive and will likely cause issues when replaced (just like you describe). If you can find a replacement chain that works if you do this, congrats. I will stick with proper chain replacement.

Por lo general, cambiar la cadena y el cassette, nunca colocar menos distancia de cadena nueva que la anterior que es antigua, es mejor tener un enlace más cadena que no menos, el KMC X10e es omnidireccional.
Check the tensioner or spring of the rear derailleur because sometimes they no longer tighten chains or have problems in the stars of these.
