My smaller range XT cassette weighs a ton, the XT hubs are pieces of shite.
My Sram X01 2.1 clutch isn't retaining tension but due to shitmano sueing sram for adjustable clutch which shitmano hold the patent for, It's not easily adjustable. Was running an E13 cassette, loved the range with the 9t but the top 3 are weak alloy and I ripped off a section of teeth, poor for a $300+ cassette.
So now I'm trying out GX eagle.
So far, ok.
Shifts ok. Range excellent.
Only raced one Enduro and rode Falls Creek Ignition so more endurance testing to come.
My sons bike has NX eagle, seems to work ok but it does seem pretty cheaply built.
My new moto comes with GX eagle and a single click shifter. Not ridden it yet.
I was happy with my X01 11sp Sram stuff but I thought I'd give this 12sp a go and it helps to have wheels and drivetrains interchangeable within the "fleet".
