Kind of curious what part of your current set up is letting you down. I am in the minority here, but I don't think 1x 11/12 groups are a huge leap forward.I've been searching for hours, so I can upgrade my hub and install this 12 speed cassette. My current 135mm Shimano hub doesn't quite make the grade. I likely need one that is 142mm+, but I can't seem to find one that supports my existing 9mm QR frame.
Well I'm new to the drive train side of things. I had the thought to update my old MTB from an English BSA, to a modern day SRAM Dub. That install went well. So next was my SRAM bundle, consisting of the GX 12 speed shifter, NX 12 Speed cassette (fits on a Shimano/ non-XD hub) and GX 12 speed deraileur. All of those installs went well, with exception to the cassette. It all packs nicely onto my 10/ 11 speed Shimano driver, but once mounted onto my frame the last COG sits so close the frame that there won't be room for a chain. I looked and noticed the cassette locking nut is about flush with the axle locking nut, and generally I see a locking nut protrude out, in most other people's builds. Maybe it's how I have the cassettes and spacers stacked? In either case when I adjust the deraileur to try and line it up with the final cog, I have the alignment screw fully backed out and it still won't come out far enough to line up...likely because there's no spacing between the cog and my frame.Kind of curious what part of your current set up is letting you down.

I'm basically uneducated in many Bicycle components, but can tell you about tearing apart dirtbikes, from many years of motocross/ woods racing...that said, I'm not sure what is considered Micro Spline, but have heard very much of XD. Sunrace and SRAM both make a 12 speed cassettes that fit a standard Shimano hub. By my recollection those had about 12(?) Splines.Doesn't every 12spd cassette require a XD or Microspline freehub? I doubt you'll find a hub with one of those and a QR axle end cap.
It doesn't help the confusion when manufacturers screw up the specs. I saw on Norco's website the other day that they listed a rear qr axle on a frame as being 9mm. Um, no.Well, the first problem you have is that 9mm is a FRONT HUB standard. Not a rear hub standard, which would explain your inability to find such a beast. 135x10mm is the rear hub standard.
