The mystery has been already solved: There exist two different large Deore XT sets of matching 12-speed cassette and derailleur: the cassette can be either 10-45t (Vado SL 5.0) or 10-51t (premium e-MTBs). The derailleurs are different, too, even if both are part of Deore XT groupset.Ouch. it is a not a1n 11-50 but a 10-44 or 10-45. Next time I get the wheel off I will count teeth - but definitely not a 50.
So I should be ten percent faster for the same cadence in my highest gear..... and therefore be able to coast up the walls I thought I could climb with the 50 I don't actually have. I'm still happy.
But embarrassed. (I've got a Shimano Deore derailleur. Some builds come with a Sram Eagle - and that can include an 11-50T)
The interesting fact is the rear hub needs no special driver when the smallest cog is 11t but such a driver is necessary with 10t cog. For that reason the 12-speed 11t SRAM cassette is mounted on a simpler hub than the 10t Shimano is.
@Rás Cnoic here has "mountainized" his Vado SL by swapping the chainring for a 38T one.
