Bosch power chewing up chains and cassettes

[Plummet]

Changed XT Cassette (now M8200, former M8100) and XT Chain at 2100 km. Derailleur changed from XT mechanical to XT Di2 approx. 400 km earlier.

Mondraker Crafty R, 120 Nm now, 100Nm since Update release date before.

Those are good values, you should be happy with them.

Maybe try running more chains, might get more cassette life.

Bosch powered ebike chewing up chains and cassettes twice replaced in 5000km. Mechanic states it is because of the narrower gears and chains on the 12 speed. Thoughts please?

that's awfully soon. I've just passed 2.5k km on Sram Force AXS 12 speed grupset paired with Bosch gen 5 and wear indicator shows <0.25 wear (3 teeth type one, first tooth does not want to go in yet). Immersive waxing every 300km since day 1.

Is that^^^ any more accurate than Park Tool CC-2 Chain Checker, and if so how much more accurate? I always take more than one reading with the PT CC-2 on different parts of the chain.

I think so, there's no "how hard do you push it in" problem, it's basically an old-fashioned, straightforward measurement between the centres of the rollers. Deadly accurate on any bike chain (flattop chains have larger dia rollers). You can see exactly what it is you are measuring as the centres gradually move apart as the chain wears. Silly expensive though and patents mean no Chinese copies seem to be available.

Wow lol. I’ve also said it many times, if Bosch does it you guys would lay off the restriction talk. Turns out I was right . Guess it’s not dangerous to trail access and human life if it’s bosch. You have to have over 60 posts on class 2+ rhetoric

You misunderstand, but that's fine. My stance has not changed that e-bikes should remain legal if sold as Class 1, even if I think there is room for evolution of the LEGAL definition.

My stuff is all correct, set up, etc.
I have three brand new X01 Eagle chains and wax them and was getting sizing correct and all that. This one went on about 2 mi earlier. I was in turbo mode which was accidental and in full on attack mode and stomped on it in about 9th gear which was a bit off as I should have probably been 2 gears lower and it popped the chain. Wasn't at the master link, wasn't shifting either.
I tend to agree that we're just reaching the limitations of these drivetrains at current power levels.
