Question:
I have XC mtb with an XX1 mechanical drivetrain. My bike guy is trying to sell me on a $400 GX AXS 'upgrade'. Is it worth it to make the move to electronic? I don't consider it to be an upgrade, as I'd be losing XX1, and gaining weight.
What say you?

AXS XX1 and GX is absolutelly the same thing. They different only in cage.
Just buy AXS GX and swap cage with Garbaruk cage for example. You will receive XX1 weight with half of price )
In GX AXS cage maded from steel and weight about 120gr, Garbaruk alu cage is about 40gr.

I think the OP is thinking of moving from the mechanical XX1 to GX AXS.

@kervelo, yes but question about loosing XX1 and gaining weight )
AXS XX1(GX with Garbaruk cage) is 370gr derailleur and 70gr shifter.
Mech XX1 is 270gr derailleur, 120gr shifter with cable and 30-40 gram cable housing etc.

He did mention that the cage was the only difference. And the Garbaruk option seems reasonable.
So, are you suggesting that after the GX transition (with 3rd party cage), I'd be near the same weight?
Also, I have a Force AXS on my gravel rig (which is fine), but haven't ridden electronic on MTB. Everyone seems to rave about theirs, so I am assuming that you also fall within that group?
Thanks!

I am in a similar boat to the OP with XX1 mechanical currently and thinking of AXS. Weight and cost are the nagging factors.

Presumably this weight saving is for replacing both inner and outer cages, plus new pulleys are required to work with the Gararuk cage? So actually quite a lot of money??? Maybe just a light inner cage gets you most of the way towards XX1 AXS mech weight from GX AXS?

It would be really interesting to know the most ecomonimcal way to lighten GX AXS as X0/ XX1 AXS seems like throwing money away for very little.

Gararuk cassette and a cheap ebay chain seem like the best value items to round off a mechanical XX1 to AXS upgrade but happy to be corrected if other have tried these cassettes and dislike them :)

edit:

GX AXS rear mech 443g
https://r2-bike.com/SRAM-GX-Eagle-AXS-R ... -speed-52T

XX1 AXS rear mech 350g
https://r2-bike.com/SRAM-XX1-Eagle-AXS- ... speed-52-T

R2 has GX AXS inner cages and jockey bolts at 44g. Assuming a carbon inner cage is available at around 10g that could be ~30-35g saved for £20 (going by Fibre Lyte/ J&L prices).

Remove the GX AXS battery cover is -12g.

So a lighter inner cage and removing the battery cover gets GX AXS within 50g of XX1 AXS potentially for about £20.

I also notice Ratio do a reasonably priced cage and jockey wheel kit for AXS at similar weight to Garburuk but less money:
https://ratiotechnology.com/product/sr5 ... leur-cage/

I'd be interested to hear more about the inner and outer cage combos eg Garburuk/ Ratio if anyone has tried these. How well do they work and how were they to fit?

Thanks!

That is really helpful, thank you!

Did you just use the stock SRAM jockey wheels from the GX mech in the Garbaruk cages? I.e. you only need to buy the Garaburuk cages to drop 60g?

The Garburuk cages are listed as 42g, the same as your XX1 cages, so I wonder where the extra 10g difference is? Mounting bolt only or something else?

@DanW, yes in bolts and pulleys. I change only cage, use GX pulleys with small adoptaion :)

"use GX pulleys with small adoptaion"

What do you need to do to get the GX jockey wheels working with the Garbaruk cages?

@DanW, there are small knob in metal plates of pulleys, you have to remove it ) Nothing special, just few minutes of work )
XX1 pulleys does not have this knobs.
