The wheels are as follows (going by a decent set of gram scales):
Meta 55 XTs wheels (not completely stock)- 1895g + 2642g = 4537gXT Hubs
Equalizer 27 Rims (19.5mm inner width)
SRAM PG970 Cassette
2.4" Nobby Nic Evo (converted tubeless with a Joes strip)
2.35" High Roller + 180g tube (not the fat one that comes with it!)
XT Skewers
Centerlock rotors (180/160)
The XM321s on the 5.5.1 come in 68g heavier per wheel than the Equalizers (for the extra 2mm width)
Hardtails - 1725g + 2088 = 3813gXT M775 Wheelset (19mm inner width, 1721g for the pair including UST valve, excluding skewer and rotor)
XT Cassette
2.0" Specialized Captain Control 2bliss (Spesh come out big, it's wider than the 2.25" Nobby Nic it replaced, wider than the 2.1" High Rollers too)
XT Skewers
Centerlock rotors (160/160)
The Control tyres are the puncture resistant ones too, could probably use XTR rotors (90g saving) and some wider tyres and still save 1.5lbs or so. 180g or so saved with a carbon bar, 100g saved with titanium railed saddle. Must be getting near 28lbs actual weight?
"What is the difference between your two wheelsets?"
Well Pro IIs on XM719s are the same width, not tubeless, probably quite a bit stronger and ~150g heavier at a guess? Given Pro II on 4.2d come in at 1803g and aren't UST compatible. The XTs are on my hardtail so I was more aftwer light weight
