They do not lock,, they clutch
Clutch on,,more chain tension, say,,,four times more on average...
Clutch off,, no extra tension, clutch off is just like any other non clutched derailleur....
If it was LOCKED you could not down shift....
The New revised Shimano XT M8000 rear derailleur has an external clutch tension adjustment screw,, I am waiting patiently...
