Has anyone done the sums? I've seen a few things that would suggest XX1 is a few pounds lighter than XT (eg Santa Cruz Bike Builder thingy) but I doubt there's that much in it
So anyone got drivetrain weights for XT double / XTR double / XX1?
thanks
I know the difference between the SLX and XT chainset is about 4 grams at best! I think the last time I actually weighed them. I haven't spent the $$$ on anything higher up the range to definitively divulge anymore...
Surely a fair test is XTR 1x10?
XTR 1x10 with a top guide is significantly lighter than 2x10.

Why? That's a far narrower range than XX1, and is a bodge really anyway.
XX1 is more akin to 2x10 XTR.
There's definitely less than 'a few pounds' in it, XX1 is about 200g lighter than XX, which itself is slightly lighter than XTR. XT a little more, about a pound difference there, and your wallet will be far lighter.
why?
I'm interested in how much lighter XX1 is vs XTR double - personally I wouldn't run 1 x 10 (although I know a lot of people do).
I was looking for the weight of the XX1 GXP crankset yesterday and in the process stumbled upon this

But there's also a dude here
Who has done a few comparisons.
Not why to you Charliemort, totally understand the question, why was to superficial who said the comparator was 1x19 XTR.
Because 1x11 is obviously going to be lighter than 2x10. And if you're THAT worried about weight then you're probably already running 1x10 anyway.
I'm not sure why 1x10 is a bodge, either.
Clearly there are a lot of things I don't quite understand.
Because 1x10 XTR doesn't formally exist, you can merely convert it. But it's more of a compromise than XX1.
njee - yes, realise that! think we posted about the same time, my why was to superficial also. Didn't realise 1 x 19 was out yet though!
yes I know XX1 would be lighter - question was how much. Looks like about 1 1/2 lbs lighter than XT double (which I currently have) or 1/2 lb lighter that XTR double
But with XX1 you don't need a guide. You don't have to faf with front shifting and you can put the Reverb remote under the bar in the front shifter position. After you've ridden a bike with that set-up it's like going back to the dark ages using a 2x10 etc.

😆 yep, that's how things move now.

Not so sure myself. History is usually written by the victors, and the battle for our drivetrains is still ongoing.
I think for some riders there's still place for 2x10 or similar. There's room for both IMO, certainly don't think we'll see 1x11 drivetrains on all bikes any time soon.
I was always a 3x9 rider but after my dream build was nicked, I decided to give 1x10 a go. I am a convert. I do occasionally miss the extreme high/low gearing but I'll happily trade that for a complete lack of chain suck. Clutch mech & top guide also mean no dropped chain so far either.
I run 2x9 on my main trail bike, and 1x9 with a top guide on my winter hack hardtail. Works for me, although I suspect i'll go 1x10 or 1x11 on both when they wear out and the prices come down.
TBH I'm increasingly tempted by the features offered by XX1 including it's weight, but the cost is still enough of a deterent, the "halfway house 1 x 10 solutions: XX "Style" aftermarket rings and modified 10 speed 11-41t Cassettes, etc hold some promise and I think are an indication of the "proper" products that will be coming out over the next 24 months.
Of course proper weight weenies never "just" but a whole groupset, there's always grams to be saved by chucking more money at aftermarket trickery or removing an unused ring or sprocket...
I'm waiting for the day when 7 speed makes a formal comeback as the "Super-light" solution by getting rid of ~30% of the Cassette mass and then we're basically back to about gearing we all had in 1991...
As it is I'm still sticking with (heavier) SLX - 2x9 until something that functions/weighs more like the current XX1/X01 can be had for something like current XT money... probably a way off yet...
What I'd realy love too, is to see Campag get back into the MTB drivetrain market, I doubt I'd actually buy their products but having 3 main players in the market might precipitate some faster and more innovative product developments... This 2 horse SRAM Vs Shimano race is a bit dull and slow at times TBH...

I'd be highly skeptical that it's THAT much. Given the cost of XX1 and the price of cassettes you're going to throw an awful lot of money at something in order to chase a few grammes. If you discount one shifter (circa 132g) the front mech (120g) and a chainring (33g) you're nudging half a pound, but then you need to remember that you're going to fit a larger cassette (XX1 40T vs XX 36T) and sooner or later you may well opt for the belt and braces approach of a chain guide anyway (circa 50g - 100g) then you're saving less than half a pound at the cost of a new drivetrain, £300 a throw cassettes, a new rear freehub etc.
Surely it would be a cheaper option to try adapting an XT/XTR 1x10 setup to see how you get on with it first?
I was under the impression that xx1 was the same weight as xx.
jeepers - never said i was going to buy XX1 - just curious.
Santa Cruz bike builder no longer has full build weights so I suspect it was wrong anyway!
