Hey everyone,
Building MTB up... I located an XTR crankset online or arms... I am using a P2Max NG PM with a woftooth ring already... question is does the crank arms kit come with the lockring for the chainring... or do I need to order the complete crankset to get the lockring as well... it doesnt actually specify anywhere I could see..
Thanks
XTR Boost crank arms only

it comes with lockring
by the way, xtr crank arms fc-m9100 and fc-m9120 both have 52mm boost chainline for 1x setup,
the only different is q-factor
fc-m9100 have smaller q-factor, 1x with 52mm CL, 2x setup with 48.8mm chainline
fc-m9120 have larger q-factor, 1x with 52mm CL, 2x setup with 52mm chainline (and 2x setup with 48.8mm CL if you use m9100 2x rings)
if your powermeter and frame doesn't require extra q-factor clearance, then you can use m9100
