I would too but there a wee lip on the lockring, its 120mm flat or 121mm with the ruler up off the lip.I'd argue it is probably 121mm
EDIT: Or perhaps scottys are off by 1mm...
EDIT: Curiosity got the better of me and it was still sitting on the bench down in the garage.
That 1mm lip is actually a rubber O-ring, so jam that ruler hard down and the O-ring deforms it to make grant total of 121mm

The Q factor on the spec sheet would be the easiest way to work it out. I probably made that harder than it needed to be. Is to do with the spacer (8130 cranks have 4.5mm spacers). As shimano are a direct mount chainring and can’t be flipped like race face ones(also fixed spindle sizes) the offset is done with spacers. BB can be shimmed a little if needed (depending on bb and frame)

I'm taking a bit of a gamble on it not mattering so much for me but it may end up more critical.
My chain will come off the idler onto the chainring 3mm out of whack as the manufacturer specifies 52mm chainline.
Its either going to work or I'll have to make minor adjustments... all failing... M8100.
Will find out in about a week.

If it’s not going to work I’ll work a trade for mt900 if you like. I bought a couple of sets

Given it's on the drive side, might put stress on the idler bearings. But maybe not immediately apparent? Guess you'll have to eyeball it.
Banshee also responded to my email.
They said 52mm chainline, and sent me this link https://www.alltricks.com/surl/what-is-boost Also said 55 may work fine, except maybe chain falling down when backpedalling in lowest gears.
So I'm going with 7100 cranks.

Thanks for all the bananas
This happens to me but I'm on a 52mm chainline with 10sp Deore. Maybe it's the Sunrace cassette and KMC chain?

Some cassettes and chains do it more. That article also had 49mm as the 'best' chainline for 142 rear spacing (prob your 10sp). But you can see it lines up with the 6th sprocket down. So it's always a compromise.
Ordered the 7100 cranks in the pushys 12% off the other night. Along with some 12sp chains, and a 51t cassette.
Forgot to order a shimano dm chainring tool though. Didn't account for that being different again. So used to the raceface stuff which uses an old isis slipned bb tool for it's lockrings.

Fear not, it is in the box with your crank.

Actually, after posting this picture, it got me thinking
When you have bought a Shimano BB in the last few years, it comes with a plastic reducer ring to fit the larger older style Shimano BB tools.
This tool does both new Shimano external BB's and direct mount chainrings.

A mate is looking to upgrade from his 2010 Stumpjumper to a mid travel 29, he loves my SC bike and was keen on the Hightower. I sent the link to the Ripmo AF, and he was like "Ibis, lol seriously?" and I'm like "Serious AF"
It's an absolute contender and looks like one of the best value bikes out there ATM. My mates 2016 Mojo has been very reliable, he's 105kg and breaks rear wheels like they're pretzels.

I was told this a few days back, that new bikes are arriving with parts missing
Bike shops are snooping around for parts to complete bikes for customers.
Never heard it was big items like forks but the bloke that told me is in the know and shifters and derailleur were the items he mentioned.
