MTB rear derailleur for double chainring Shimano 12V. SLX M7120SGS

Having introduced 12-speed cassettes on its top-of-the-range XTR groupset, Shimano is now extending this to the very popular Deore XT and SLX groupsets.
However, this isn't the only change, and it's indeed two brand-new groupsets that the Japanese brand has just presented.
The rear derailleur will be available in two versions, for single or double chainrings.
The length of the clevis remains unchanged, but the angle with respect to the frame is different.
They are perfectly identical in all other aspects of their design, and both use 13-tooth rollers mounted on bearings.
