Are Box one good derailleurs?
My XT medium is wearing in the pivots and getting sloppy.
Know nothing of Box in the real world. Planning on racing enduro in Tassie and would like good dependable power shifting on terrain.

One thing to consider, especially if travelling to Tassie to race, is the finding/borrowing Shimano replacement parts will be more likely than Box parts.

I had a box 3 on my craftworks and it was terrible.
It had more play then a Shimano tourney and couldn’t be made to not skip in 2 gears (this is with a box cassette and chain).
I ended buying a microshift shifter and derailleur and it is much better

The clutch on Box 3 is not adjustable and can't be switch off/on, it's always on.
Box 1 can be adjusted but I'm not sure if it has an on/off switch.
I didn't have any troubles with my Box 3 derailleur skipping, in fact it took minimal tuning to work. But I also don't break derailleur hangers with sheer leg force. ;)

From what I hear on RB, Shimano 11 speed is pretty dependable - I wouldn't know, I'm stuck in 9 and 10 speed world.

It looks like Box 1 derailleurs are compatible with Shimano 11 speed road shifters, but it says nothing about MTB shifters, so you would likely need to get a derailleur and shifter combo. A new Shimano 11 speed derailleur would probably set you back less than a new Box 1 shifter and derailleur. Besides, Shimano clutch is both adjustable and switchy on or off.

I agree with @creaky, it would be easier to find Shimano spares than Box components.

TL,DR spend money on bike parts!

Why is the clutch on Shimano rear mech adjustable? I’ve never felt the need to adjust my Sram derailleurs. It either reduces chain slap or it doesn’t.

It can lose tension with use (or maybe ham-fisted force?).
I've never had to tension one, but the option is there if you need to.

Mine lose tension over time. Even quicker since installing an oval chainring as the derailleur arm is constantly moving in a small arc with each pedal stroke.
I also like higher than factory tension on the clutch to keep the chain slap down. Current Deore needs increased tension from factory as I get more chainslap than with previous XT.

Maybe I’m not very observant but I’ve never had my my Sram mechs lose tension.
Is it because Shimano offer adjustment that it comes loose? Chicken or egg?

I add more tension on some bikes than others. Some can handle it, some have shifting effected. More is better when I can.
