- Drive train weights – XT / XTR / XX1
Surely a fair test is XTR 1×10?
Why? That’s a far narrower range than XX1, and is a bodge really anyway.
XX1 is more akin to 2×10 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.Posted 4 years agojonxmackMember
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.Posted 4 years ago
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 doublePosted 4 years agoboxfishMember
I was always a 3×9 rider but after my dream build was nicked, I decided to give 1×10 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.Posted 4 years agocookeaaSubscriber
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 – 2×9 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…Posted 4 years agoPJM1974Member
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
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 1×10 setup to see how you get on with it first?Posted 4 years ago
