with the 16t cog a conversion doesn’t have a gap
The gap is bloody irritating for me as the shift in gaps goes 2,3,3,2,3. I find those bold 3’s extremely annoying
A 10 speed XTR 42t cassette is lighter than 11 speed shimano as well.
Well the 11-36XTR is 270g and the hope 40t is 74g. You take a tiny cog out which might weigh 10g leaves a net 334g which is same as the XTR 11-40 at 330g.
I’m currently wrestling with whether to go 1×11 with M9000 shifter, mech and XX1 cassette. I can get the range I need with a 30t front but the 17% jump from 42t to 36t is a potential deal breaker. Longest climb I did in 2014 was 345m and I remember being grateful for smaller cadence jumps on that. I think the approx. 1/2lb of weight saving doesn’t make up for cadence issues.
For doing really long distance on my Spearfish the M9000 34/24 front makes a lot of sense paired with an XTR 10speed 11-34 cassette if you can run 10speed chains on M9000 rings
