Changing a trek 12 speed to a 10 speed???

[Lampy]

Hi all
I’m a newbie but got a question.
I’m at a stage where I have just fitted a new shimano chain to my 12 speed. It’s noisy in the lower gears. Sounds nasty.
I have changed it back to the old chain and it’s fine.
I measured the wear at 0.65 and it’s the second new chain which is the trek o one for this bike.
I’m guessing it’s the cassette that’s now worn so I’m thinking shall I change it to a 10 speed cassette. I can get the M6100 which is the same tooth range 10-51t as original.
Will this work and what else will I have to change apart from the chain.
I’m guessing I will have to set the derailleur with new stops etc.
is it better to just get a new 12spd cassette.
I don’t need all the gears but I do use the extremes at times ie 10 and 51.
Bloke at a shop told me mine is a micro spline.
It’s a 2020 trek powerfly 12 speed.
Shimano cassette M7100.
Any thoughts out there.
Cheers lampy

Keep riding the old chain/cassette until it skips.. you might get another 1000km out of it.

I’m also thinking of going from 12 to 10 in the future on my Cube but it’s the indexing that will be the problem.
Think you are going to need new shifters with 10 clicks over the same cassette width which on mine raises another problem as the shifters are part of the break leavers.

11 speed xt linkglide is the ducks nuts for e bike drive trains. It's robust, cost effective and works well.

Ps shifters aren't a problem. Just buy the right configuration unbolt the old and bolt up the new.

Shimano Microspline is just for 12 speed, 10 speed will require an hyperglide freehub, 10/11 speed derailleur and 10 speed shifter

Yep, but also and easy thing to change.

I’m hoping to kee riding on the old setup until gather the stuff for a new drivetrain. May just have to replace the 12 cassette as it seems to work well main reason for change to improve things and maybe bit more robust.
Now I’ve mastered chain changing I guess I may just have to change chain more regularly. I was hoping the chains might last longer on less gears as more room for more robust chain.
