To answer a few queries – just had my first ride on the full set up tonight.
The Alu sprocket cannot be detached.
XTR chain rings do fit the crankset as they are both 96bcd.
I fitted XTR shifter because for £30 more it’s very worth it.
Very simple to install and set up.
The shifting is very close because it’s a different set of ratios from SRAM 1×11. I felt like I hadn’t changed gears at times, when I had – I’m used to running SRAM 1×11. Weirdly 32×42 (I.e. Lowest gear) on XT feels slightly different from SRAM. It’s a very quiet set up too.
Initial impressions are very good and I can’t fault the value.
