I'm on 1x9 with a bottom gear of 30/34. It's manageable on the steep tech, but hard work in a lot of places. I reckon that a 32/42 bottom gear would be fine, and I don't miss gears higher than 32/11 (I ran a 32t ring for a while).
Surely a 1x10 is going to work out a bit lighter than 1x11? Although it doesn't seem to be cheaper..
A bit being weight weenie territory though isn't it?
Are you heading to the top end groups or the functional ones?
Nice range of 10-42 will give you a big spread and lots of choice on chainrings for terrain
Mix and match a nice crank SRAM cassette and 11sp shifter and mech of your choice
Weight weenie - yes. My XC race bike was just too heavy at 28lbs so yes, I'm going back to weenie-ism for this one.
And for that reason, I'd be choosing XTR I think, assuming there's a benefit. An XTR mech and shifter isn't prohibitively expensive. But I'd probably keep the M970 cranks.
I like the xD idea but not sure if a freehub is available for my Bontrager Mustang wheels.
Ignore the weight.
Go with 1x11, upgrade kits are cheap. Less gaps between gears and/or bigger overall range. If budget allows go for an XD driver.
Edit: if you have the unfortunate weight weenie mental problem then especially check out SRAM XD cassettes.
I went for a Garbaruk cassette - https://garbaruk.com/ 11 speed - good range, weighs 2/3rds of Xt and you don;t need to switch to an XD hub. Been on my fat bike for a few months with no issues.
Cheaper than SRAM too.
Get the extended mech cage to match.
I went 11 speed purely for longevity - I can see 'top end' 10 speed either disappearing or gettign expensive the way that 9 speed has.
11 speed shimano mech has the same pull ratio as 10 speed, but handles big sprockets better.
Ignore the weight.
No, weight is important to me on this bike, not interested being told not to care about it.
However, I may care about weight, and I may be prepared to buy long lasting XTR components, but $260 for a consumable is a ****ing piss-take.
Looks like XT 10sp is only 11-36T anyway, which isn't worth the change. An 11sp M8000 cassette seems to be 430g or so, about 130g more than 9sp.

Well get rid of the rear hub, buildit on a DT or something and go Eagle!!

£170 for a cassette?

I edited the comment. 😀 There are 11-42 10spd cassettes and stuff like extender cogs but the jumps are pretty darn big.
That's why I wanted you to check out XD.
XT M8000 11-42: 447g, 69,26 € right now at bike-discount.de, the aluminium 42T cog will wear out the fastest.
SRAM XG-1150 10-42 XD cassette: 394g, 85,32 €, ALL STEEL!
Top end components are not expensive because they're long lasting, sometimes quite the opposite. Some will compromise durability for weight savings.

Is the XTR long lasting? For less you can have a steel 12sp GX or for half a GX11.
XG-1175 Full Pin Cassette – 325 grams – $144, €150, £115
11sp 11-40 XTR
I've seen xt 11x shifter, mech, cassette and chain for under $300 aud. That's my next uograde. $260 for just a cassette is actual Cray Cray
The OP was probably looking at the 11spd XTR M9100...

I was commenting on the Garabuk one.
I like the xD idea, but then there's the freehub issue.
That's easy.
Get a new wheelset too, save some more grams!

If weight is a significant issue then it's cheaper than an XD driver+ SRAM cassette. Particularly if you want a 50t largest cog.
I don't want a 50t large cog, 42 is plenty. And of course you don't need a new xD driver every time.your cassette wears out.
fair enough. You were asking for lightweight solutions in your OP, there was no mention of price being a consideration (beyond 10 and 11 being similar prices).
You want cheap, light, high performance... Then just buy a 2nd hand 11spd SRAM setup off someone who's upgraded to Eagle.
My last X01 11spd mech cost about £70 in superb condition, shifter £35, cassette I picked up a barely used one in superb condition for under £100 and a new 11spd chain isn't much either.
AND... The only drivetrain lighter than an X01 11spd is XX1 11spd! And that's only by a few grams...
This "How much for a consumable part" logic is bollox by the way... 9spd cassettes at £30 a pop is fine, but I used to get maybe 600-800 miles out of them offroad before they were trashed. I've had 5 chains and well over 2500 miles out of an X01 cassette before! Also you don't have multiple chainrings to wear out either...
Surely if you're trying to save weight then the Mustang wheels will need to go too?
If you've got 2.1kg of wheels then I'd replace them with something around half a kilo lighter, ideally with an XD freehub and cassette (I know mikewsmith absolutely creams himself about Sram stuff but they have done this much better than Shimano) with the shifter and mech of your choice (if you can afford it my choice would XTR too, but XT isn't much heavier and quite a bit less money).
A Sram GX cassette is an OK weight, lighter than XT. If you're feeling flush the top end (X01/XX1) Sram cassettes seem to last like nothing else. I've gone through three XTs on my other bike in the time I've had one Sram XX1 cassette, although I did have to replace the biggest (aluminium) sprocket on it after 3 years.

I thought that was a bit strange too. I'm not a weight weenie but the bike will feel a lot better if you upgrade the stock wheels and get something ~500g lighter vs if you lose 50 grams on a cassette or something... Which you will never ever feel.
The Mustang wheels do need to go, but that's a bigger expense, and I'd rather not be forced to do it all at the same time. Although mine weigh about 1850g or something IIRC, they are quite narrow.
50 grams on a cassette or something… Which you will never ever feel.
The point about weight weenieing is that you have to do it all. You won't notice 50g on a cassette but you will notice 50/100/150g saving on everything.
Weight weenieing on a budget is about choosing best value for money. I saved a load of weight by going 1x9 (at zero cost), now whilst upgrading to 1x11 will cost money and add some weight back it will still be lighter and not overly expensive - not compared to new frames or wheels etc; but importantly it will also improve the ride giving more gear range.
9spd cassettes at £30 a pop is fine, but I used to get maybe 600-800 miles out of them offroad before they were trashed. I’ve had 5 chains and well over 2500 miles out of an X01 cassette before!
I've heard this before about 11sp and also that they don't last any more. I'm not sure why. It may be that given the lack of chainrings you spread the wear across more sprockets - certainly this is the case on 1x9, I use far more of the cassette than I used to.
And of course you don’t need a new xD driver every <span class="skimlinks-unlinked">time.your</span> cassette wears out.
I'm, guessing you are on about the people who didn't lube them at the start very early days? Again put some anti sieze on there and do it up as it's designed and then you can remove it and reuse it.
If you don't want to go with new wheels right now then just get any 1x11 upgrade kit with a non XD cassette. When you change the wheels just buy one with an XD driver, shouldn't cost any extra over Shimano. Buy an XD cassette then, your current one will probably be worn anyways. You can get a lighter AND more durable cassette then, and when you will start a new thread some time from now "which 12spd groupset to go with" you'll have an XD driver already.
Good point.
But I’d probably keep the M970 cranks.
dont forget to budget for a NW ring
If he goes NN it will be lighter
Well I do get the WW bit
I train and race in the mud on 1x10 xtr and race on 1x11 xtr.
I love my M980 1x10 (11-36), hard wearing, great quality, changes faultlessly under load and lighter even with XT cassette.
The 1x11 xtr (11-40) is ok. It has more range but the quality esp the cassette doesnt seem so good and the changing is fussier. It's heavier and although the 40 means I can use a 32t front more easily its not life changing.
I've not sold my 1x10 when I've 'upgraded' and suspect I'll go back to it in the end.
