SRAM’s GX Transmission is more refined than X0 and XX
Вставка
- Опубліковано 1 лип 2024
- We smashed SRAM Transmission X0 with the equivalent momentum of a hypersonic baseball, we tried to drown it underwater, and we sent it to outer space. It survived it all. Now, SRAM has released the GX version of this mountain bike drivetrain, so we're checking out what they've changed so you can decide if this $1,099 drivetrain is right for your ride.

*Disclaimer:
To best describe the strength of the various derailleurs we tested, we opted to compare the momentum of our pendulum to that of other "real world" moving objects (however likely/unlikely they may be). We chose to look at momentum carried by the pendulum, as opposed to the actual force delivered to the derailleur, because we do not have the tools and equipment needed to measure that force. If Dan was unclear at any time and implied that the impact force was identical to that of a hypersonic baseball, as opposed to the momentum of the pendulum being equivalent to that of a hypersonic baseball, it is only because his physics education does not exceed that of a college physics 101 class. If James made any calculation errors in the video, it is only because he was in the middle of finals week in his physics undergraduate degree during the filming of the video, and not because he didn't take every possible measure to ensure the accuracy and clarity of his comparisons, up to and including checking his methods with his classical mechanics professor.

The spider power meter is actually more accurate than the spindle power meter (±1.5% vs ±3%), and it measures full 360° power. The spindle power meters only measure power from your left leg and doubles it to get full power.
best power meter is dual garmin rally in pedals!
Hahahah, you know what I did, I glanced over the power meter information and when I saw ±1.5% vs ±3% thought "oh, higher number, more accuracy."
Clearly didn't think that one through, thanks for pointing it out. I'm definitely not the target market for that specific product.
- Dan P.
The e-Bike ring should work with the spider power meter, 104BCD.
@@superjimnz The spider power meter takes a special thread-mount chainring, not 104 BCD - I have the spider power meter XX crankset on my Stumpy Evo, and I have the regular 104 BCD T-Type ring on my Levo. Two totally different mounting systems.
@@senallttam I meant the existing Quarc AXS DUB Zero power meter that people might already have, which uses 104BCD
I have the GX, and I must say the coating on the cassette and chain of the X0, XX models is a noticeable improvement in smoothness and noise. The GX works the same and is maybe more durable, but the shifts are loud and don’t have the immensely smooth gear meshing the other models have.
Yes, I do have scratches (some of them deep) on the derailleur, but in crashes I always managed to bend the cage which surprises me that people manage to do the opposite.
My favorite part of this will be watching the price of regular GX AXS drop
This is actually only $50 more than a GX AXS drivetrain.
- Dan P.
Hahah so relatable, just yesterday i was checking some prices
@@FanatikBikeCo GX AXS upgrade kits cost ~$400 in Europe.
@@Silkl4sh I was referring to an entire drivetrain. At this point in time one does need to buy the cranks and chain as well.
- Dan P.
@@Silkl4sh And $400 for a lot of chain slap and the DR flopping around on the older AXS.....
Wow! Very informative and answers some of my questions
Thank you
Our pleasure! Glad we could help.
- Dan P.
I have XT and it's been a little finicky the past couple rides... I know it's good but it needed a tune-up and I was bugged that it had been noisy, skipping gears etc. Then I see today the launch of the new SRAM GX transmission and am half-considering upgrading. But then I also spent an hour cleaning and tuning the derailer and it's running 100% again with shifts smoother ever, so you could say I'm happy with XT haha
I think this is sweet, but wouldn't buy for $1k to replace something already working fine. If I was building up a new bike, that's a whole other story -- I'll probably will get transmission for the next bike
check your indexing, b tension and cable tension. xt super easy to work on works greats when its tuned correctly.
@@matta8369Yeah. From what I hear, the entire XT groupset is really good.
To be honest I snapped my xtr12 spd derailleur cage in the spring and have been running my xt 11spd since and it works great. I wanted to replace it but It's been awesome even with the 45t 12psd cassette.
@@matta8369 Thanks, yes after I did that it was running amazing!
Thank god the fixed the battery issue. I was constantly knocking my battery off riding fakie down gnarly rocky rooty chutes.
We want to see that!
Great review as always thank you!
Review? You know they only test "review" sram groupsets right? This is a paid commercial video not a review. These guys are under sram shills
Thanks, glad you found it informative!
- Dan P.
This is not a paid commercial, Sram pays us nothing. We're a bike shop, so it makes sense for us to make videos about products we sell. Here's a video we did about Shimano 12 speed. ua-cam.com/video/jjoFpahXTrw/v-deo.html
Here's a video of Dan saying he doesn't like AXS: ua-cam.com/video/pi9OS84reXk/v-deo.html
I personally run all Shimano brakes/drivetrain on my bikes, and have for years. Don't see myself changing anytime soon. Might switch to the new Shimano Linkglide 11sp though. Hope to make a video about it soon.
- Logan at Fanatik
I love how you can customize the entire bike from the frame up. Don't know if there's any other mtb sites like that, but that's cool I think.
I built up my bike on their site last summer. It’s so awesome. I got an allll black sworks stumpy evo
The e-bike T-Type ring is available with the 104BCD, so should be able to be used with the existing Quarc AXS Dub Zero; it is steel and limited to 34, 36 and 38 teeth though.
cool vid..!! the new GX crank arm would be even sweeter in black to match the chainring
@@irfuel 😂
i assume the sweet spot would be to mix in this groupset with the x0 casstte, which seems like it still has the xdome technology that the GX doesn't have. tangible weight savings and definitely extremely durable. I'd be interested to see if this new GX cassette holds up any better, but I have a feeling that those single piece cassettes are still king (and honestly one of the best selling points of sram groupsets, both for road and mtb)
This is what I just ordered. Considered cost vs weight for the whole setup. Did GX derailleur, XO cassette, GX chain, Used pod controller, and wolftooth chainring so I could use my xo1 eagle carbon cranks. Once more colors come out I’ll upgrade the chain.
I want to love sram drivetrains, I really do, but my cable GX AND GX AXS shift like utter crap compared to my Shimano XT. Like it’s not even close. I hope transmission improves on the shifting.
My local bike shop has had a few of them coming back for warranty replacement
My mechanical gx derailleur was replaced under warranty too.
Jockey wheels fell out…never to be seen again 😂
@fanatik does the bash guard on the chain ring work like a chain guide as well can’t see the one I have on my trek fuel exe running over that?
Composite looks nice for longer. When aluminum is scratched it exposes the bare aluminum, composite is the same color all the way through.
Would love to try one these out ixjust bought an new embt came with XT one not used it yet but always fancied one these just the price is crazy after spending 5k on the bike in a Jan sale or would been 7k so kindda assuming XT will do for a while i think just cause its brand new embt never had one before not had an mtb for a few year's now so not tried tge new geometry of them either so its going to be an experience lol
I have an Ibis V2s and I’m considering T Type, what i’m interested to know is how the crank lines up to the v2s 155mm chain-line, for instance do you space it out after removing the ibis isg05 mount as you don’t need it anymore and how close do them bash guards get to the chainstays as the rings are always very close on the Ripmo ✌️
You can run the ISCG mount, or not, just a matter of spacing the DUB BB out or not.
The bash guards sit outside of the chainring, so they won't hit the frame.
- Dan P.
Smashing from the side is a common use case but how would this derailleur do with a 1" stick stuck in the spokes wrapping it backwards?
Hey, do you have any info on whether you can change just the derailleur (for the old gx axs) and use existing chain and sprockets? Are the rollers on the new one any different then on the old one? Thanks
SRAM alleges that you have to use T-Type chains, cassettes, and chainrings. If I remember correctly the spacing on the cassette is a little different. I have not tried it with any other chains or chainrings.
- Dan P.
I mixed up X01 with GX derailleur. They must have changed the design on the GX for a reason . Battery is less exposed than on the higher price models .
@fanatik what is the chain slap like on this model? Is the clutch stronger than the previous generation AXS GX?
It is extremely quiet. The way the derailleur moves is a little different than a traditional derailleur, so you don't get the loud noise that happens with AXS stuff.
- Dan P.
i've some fine 5dev cranks and absolute black oval rings (t-type compat), am i able to buy the rest of the drivetrain ala-carte ?
So when will the bike builder allow for a Rail29 to be built up? I seriously need this! COME ON!
Cool ...... can you replace just the cranks of the GX, XO T type groupset etc with something more sexy, like some RaceFace carbon
Not yet, as the chainring is different. If I was to guess, I'd bet aftermarket options will soon start popping up though. - Logan at Fanatik
Can I use my existing Hope 155 specialized ebike cranks with the GX System?
It’s actually known in the industry as “tickle down”
-bean the cat
This only makes sense on a complete IMHO too expensive. The only benefit is shifting under load which no one cares about except XC racers. The climbs here are so steep i dont shift a lot from lowest to hardest and the other way around at the top and bottom of the trail. The only thing i care about is the chain staying on. I break the stuff regularly and a full gx derailleur is cheaper than any replacement part on the transmission so it absolutely makes no sense for Enduro riding IMHO. The old mechanical and axs stuff is good enough. I love that they bring this new stuff out because it makes the old XO1 stuff so cheap. Now i can get a XO1 derailleur for 159 EUR and a gx for 88 EUR and a XO1 cassette for 248 because. My only fear is that they discontinue the GX mechanical.
Where do you get the compatible bottom bracket?
I get the that the GX is heavier, different materials, and cheaper. But the title says it's more refined. Somehow after watching the video I missed the "more refined" part. Anyone have an idea?
i want all gx transmission benefits but i'm not going electronic. i hope they come out with a super hardy analog version
One of the main points of transmission is that there’s no adjustment needed and install is easy. Therefore it has to be electronic lmao 😂
@@aledska oh thats all? I never have to fuss with mine's adjustments. I have had to replace after a good bashing though.
@@TheLeesto then don’t go electronic and keep getting regular derailleurs the future is going electronic 🤷🏻♂️
@TheLeesto cables are never going to be as precise as a programmed motor. Therefore all transmission will definitely be electronic.
Does the clutch still suck?
if I just want the GX derailleur, shifter, and battery it should just bolt right up to a 2023 roscoe 8 correct?
At this point you have to run the Transmission cranks (chainring) to use this system and get all the shifting benefits. We have not tried it in any other combinations.
Which is to say you need to get the entire drivetrain, unfortunately.
- Dan P.
So removing the sacrificial and going straight for bending your frame is a good idea? Yet more tech I won't be buying
Just put the GX on my E-bike it's a game changer!!!
Was wondering if the deraulier is attached or held in place say when swapping out tires. Kind of looks as though the axle holds it . Thanks
The derailleur bolts to the frame like the hanger normally would.
@@or-ian6973 are you sure it is bolted ! It sure looks like if you remove the axle the deraulier is unattached
@@or-ian6973 will do . Cheers
Small detail but it’s either chain guard or chain guide right? Doesn’t look like both will fit.
Oh shoot, that was something I wanted to mention in the video, looks like I forgot to. You are correct, one or the other.
- Dan P.
nice 👍
It's pretty crazy how Sram's new T-type brakes don't require any rotors.
According to the Fanatik Bike Builder
Uh oh! Shoot us a message at sales@fanatikbike.com with what you were building and we can look into it to try to fix the issue!
I've seen a transmission derailur combination with sram red axs front 1x chainring.. Pretty sure they work together.
don't believe sram when they say you need to buy a new crankset for your drivetrain. At the most I could see you needing a new chainring, but wolftooth will have you sorted on that.
Any SRAM chainring with 0 mm offset would be just fine i guess as the Transmission chainrings have 3 mm wider chainline.
@@dvoobyep Wolftooth now has a chainring for flat top and proper spacing for older sun style cranks
@@Aniqa101except flat top chains are narrower. But Wolftooth has you covered for that as well
where I live because south Africa has horrible trade agreements the sram t-type groupset sells for 3.5k usd (on sale, 4k full price ) so i could only ever dream about it ,
That's okay, normal derailleurs work great!
- Dan P.
Sounds like you have an excuse for a flight to the us or Europe. Still cheaper!
For those of us who don’t race, what will be the main benefit of shifting under load? Lazy shifting?
Hahaha, in my opinion, yes. You definitely don't have to think as much about what's happening down there. With the electric stuff (AXS as well) there's no sensory feedback from the cable through the shifter about what is happening at the cassette, so it is harder to get good shifts. Transmission kind of solves that problem, but with AXS it always felt pretty pronounced to me. Lot's of clanging around down there.
- Dan P.
I talk about that in here:
ua-cam.com/video/pi9OS84reXk/v-deo.html
- Dan P.
Technical climbing is a situation I’ve found it helpful, but I also am a racer that wants the other performance benefits so it was a good buy for me 🤷♂️
Yeah, good point
What's the clutch strength like? Chain slap expected as in mechanical GX?
I am not experiencing what I consider excessive or undue chain slap, but I also never felt like that was the case with mechanical GX, which I have run for a long time. So maybe we have different tolerances for what that means.
Anyone else have any feedback?
- Dan P.
@@FanatikBikeCo I definitely noticed less chain slap noise after switching to Transmission.
Has anyone mentioned that the cassettes are now using pins in the three largest cogs (in XO and XX) where in the previous AXS generation all the cogs were machined from one piece and pinned only to the largest cog?…and that the chains are now basically copies or SRAM Red road chains…
You are correct regarding the cassettes. Regarding the chains, if I remember correctly there are differences in the chamfering of the plates on the T-type chains vs the Red chains.
- Dan P.
@@FanatikBikeCo yes seems right due to the differences in shift ramps from the road to mountain cassettes. The flat top links that are found on the Red chain looks the same so maybe they are taking the same chain and passing it through a different machining process once the chains are linked. So it may reduce their overall cost as far as designing and producing a completely different chain from a separate segment of cycling.
Pay more, get less??
Where do they get these prices? 1600 USD VS 1000 USD? The Shimano XT m8000 is 90 bucks. XTR M9000 Shifter 100 USD. Works amazing and I can shift through the range with 2-3 presses.
is this new groupset compatible with a specialized enduro expert s3 2023???
Unfortunately it isn't. The current Enduro does not have a UDH rear end so you can not mount transmission on it.
What shifter do you like most?
I personally like the new "pod" better than the old paddle remote.
- Dan P.
Can you use old cranks and upgrade the sprocket with this new system?
It uses the 8-bolt pattern, so if you have the XX1 cranks intended for power meters, I think so... if you have the standard 3-bolt you will need to wait for an after-market solution. Also, I believe it's 55mm chain line now, which many recent bikes already were... but 53mm might not work exactly as intended.
@@superjimnzcorrect. Wolftooth has the right chainring now for 55m flat top setups using older dub cranks
So the power meter not built into the unit, its an optional extra?
Correct!
- Dan P.
why isn't Shimano coming out with their own wireless transmission?
Shimano does their own thing in their own time. It took them ages to come out with 12 speed group. Just installed XT 12 speed on my MTB and it is so goooooood
Is there an oval chainring option with Transmission?
Do believe Wolf Tooth will have some oval options, but nothing stock from SRAM
What’s messing me up is I don’t want to pay for xo but I hate the gx crank, chain and the cassette lol. I hate the chrome! lol. If I can find xo a bit cheaper, I’m sold
Wolftooth makes a compatible chainring now for older style dub cranks. 0 offset. So buy the GS derailleur, xo cassette and whatever cranks you want.
@@or-ian6973 ended up getting a deal on xo
Is there any way to rebuild my specialized chisel to install udh?
Unfortunately, no, there isn't.
- Dan P.
pretty sure sram can easily make a cable actuated on this one, they just prefer not to. gotta love those no hangers
They have a patent filed for one they just have not done anything with it
Wouldn’t work the same. A lot of the benefits are in the software.
@@or-ian6973 it would work exactly the same the only thing the softness does is stop people from shifting multiple gears at the same time if you are a decent rider you can learn how to do the same thing but also be able to shift faster when there is no load getting the best of both worlds
@@nickrossi7454 what about the safety features? Wouldn’t have those. Would it work …yes. would it be the same or better than a hanger style derailleur? I really doubt it.
@@or-ian6973 what safety features
Arent bash guards on XO also composite? You said at 1:38 that GX are composite and XO are Aluminium, but I think they are the same. XX and XX SL are Aluminium tho.
They are aluminium on the XO Transmission version!! I have it on my bike!!
@@TheDiablosix6six really? That's nice, I assumed they are comp from looking on the photos, I'm still waiting for my XO mounted to new Propain Tyee, so your message made me a little more happy, thank you :)
Yes, good catch! The X0 and GX share the same bash guard, the XX uses an aluminum version. And I was wrong, they are not compatible with the chainrings from the other other model.
- Dan P.
@@Afera_88 Sorry I thought u said XX!! They are plastic!!
thx God, the small replacement part is only 20$. Still, if I destroy my mechanic derailleur I just replace it. And I can do it a few times. Example, retail price: this beauty x0 - 660 euro, mech xt - ~110euro. The reasonal choice for most of the ppl is simple.
X0 and GX are super close in price right now to justify GX over X0. 1100$ for GX and if you do minimal research X0 can be found new from a shop for around 1350$…
From a show? What kind of show?
can i run the xo crank set with the rest of the drivetrain being the gx t type?
Are you talking about the T-type X0 crank set? If so, yes.
The old X0 crankset/chainring allegedly doesn't work with the new chain.

Also, the chainline would be off with the old model.

Man, those gray cranks look like cheap plastic on video. I'm sure in person they look better.....I hope.
Looks weird next to the burnt umber pedal I think too.
Does moving to this transmission mean that I'll have to ditch my 5dev cranks??
Currently, yes. I can only imagine lots of companies are working on T-type compatible aftermarket chainrings and will be available before long.
- Dan P.
@@FanatikBikeCo deal breaker for me...for now
@@DZigWolftooth has such chainrings now. I’m keeping my x01 carbon eagle cranks.
The older cassettes were one piece on the GX. I have one on my 2016/17 trek fuel ex 8. Now the GX cassettes are all pinned which is bollocks. Considering I paid a premium for the bike. Does annoy me to no end that the quality is going downhill rather than setting bars.
Cool. Now Sram, trickle it down even more to cable operation. And make it affordable.
A lot of the key features rely on the fact that it’s electronic, so cable operation would get rid of those features making it more like a normal sram gx
Being not affordable is also another flex factor for those who can.
Your a big old dummy 😂
You already have existing cable options. Why do you folks always want everything, but also want it cheap?
@@slowcyclist4324 I want the direct mount technology but without the electronic bullshit. And I don't want to sell a kidney. Pretty simple really.
Have to disagree re mech impacts... Ime it is mainly the cage taking riding impacts and either clipping that on rocks or hidden stumps etc or sticks getting stuck in cage & wheel. Laying the bike drive side down isn't the concern for potential consumers!
And basically saying you didn't test real world impacts for 'video entertainment' doesn't really cut it for a review & test video!
I guess it's good you admitted (after the fact) the impact testing was purely for entertainment (and obviously garnering sales!) & not a serious review video. Missed opportunity to really test this system v traditional.
Good that the cages swap easily tho... So well done sram. How long the support parts for remains to be seen of course.
Can these be mounted on a non UDH frame? I have the BMC URS LT Two that came with the SRAM AXS GX 12sp, love it but tired of bending the hanger 😛
Test rode it today… was pretty under whelming, shifting is way slower than expecting and under load shifting is no where near as refined as Shimano. But I look forward to testing the cable version when released.
I really don’t think there will be. The shifting comes from the software, and does the crash safety features. Seems like most of the advantages would be lost going to a direct mount mechanical derailleur.
it's too big, doesn't matter if you can stand on it (rear mech), after few months of riding it'll be destroyed I guess.
exactly what's happening with GX AXS rear mech.
I've upgraded my rear mech to XT 11s and it works great now
My xx1 transmission cage bent like a tin can...
Hi Brooks, sorry to hear that, that's frustrating.
We don't have the GX cages in yet, but if you decide to keep using the derailleur, it might be worth trying the GX cage. With the steel back plate and no cut-out in the front plate, I suspect it's stronger. If you just need to replace it asap, we have the X0 (and XX) ones in stock:

- Dan P.
Yeah, I'll stick with mechanical. My next replacents gonna be Shimano. Their clutches are way better anyway.
I replaced my gx mechanical with xtr mechanical
The new axs crank arms look ugly compared to the gx cranks I have on my bike now.
what I want to know is how bad/well this works with a shimano cassette and chain.
My guess is horribly. Chain dimensions of the links and the cassette ramps are totally different.
Both companies are now using similar technology and ideas to achieve the shifting while under load.
@@MTB_CRZY i found out it would work perfectly fine if not for the 3mm offset difference on the new ttype and the artificial limitation of less micro adjust than axs to make it incompatible on purpose. Oh well. No money to sram from me.
Just space the derailleur pulleys 2mm inwards and you're good to go.
Will the GX work on a 2023 turbo levo ?
Yep, they have an e-bike specific option. - Logan at Fanatik
The problem is the majority frames can’t run T-Type. So the industry has presented a problem either the masses buy a new bike or they slowly wait for manufactures to adopt UDH design. I suspect Shimano isn’t ready for UDH or their version isn’t ready.
If I could convert my 2023 Polygon T8 to UDH I would and I suspect thousands others would too!
Wireless derailleurs are bike industry hair splitting when it comes to the term 'upgrade'.
when considering the overall effectiveness and efficiency of both wireless and cable systems the difference is negligible . it's like the difference between cloth seats and leather in a car . both will perform well but one will cost waay more due to the coolness factor.
Of course when someone pays much more because of they are enamored with prestige , they will argue endlessly , searching for even the minutest difference to justify their purchase .
It's fine to "upgrade " if you can afford it but dont fool yourself into believing it's that much better . It ain't !
When I see people standing on the derailleurs im seeing the frame flex. Id rather have a replaceable bendable link than 100% force going into the frame.
GX cassette look cheap imho. Coating looks exactly the same as old HG53 DEORE cassette. Other than that it's nice
Hahahah that was my first thought as well.
- Dan P.
For the price difference between the GX group and X0, I would take the GX and swap the cassette for a Garbaruk one. Then it's lighter then X0 and still much cheaper...
I truly question why X0 is even there if you look at price/weight now they released the GX version. It's just not worth it anymore...
Agreed. But garbaruk doesn’t have a flat top compatible cassette. Maybe you’re thinking of the regular AXS stuff.
Cheaper, but still pretty damn expensive.
Agreed
Agreed but everything is expensive these days. When I compare it to things like food and gas I’m not that upset about it.
@@or-ian6973 I'm seriously considering a Pinion gearbox for my next bike. Expensive, but needs no tuning and very little maintenance, and will likely last the rest of my life.
Just waiting on what Pinion can do next. Imo that's the future. If I want something new, I'd rather get really something new.
What is the point in spending $1300 on this thing when my mechanical shifts flawlessly?? Just another piece of bling, I guess. Not for me
This is made for xc riders as it shifts well under pressure. You guys don't need it
Trust me, once you ride with it, you’ll know. My wife who rides a Top Fuel 9.7 XT recently tried my Fuel Ex 9.7 with the XO and she wouldn’t ride her bike after. So I had to put the GX on her’s lol. It’s a game changer and makes a HUGE difference even if you’re just cruising along. It’s effortless and just so dang smooth. Words cannot describe it. I’ll never go back to Shimano or mechanical.
So you can't run a mullet setup with a T-type?
You can.
- Dan P.
ask your friend how many "old school" drivetrains he had broken in the same amount of time?
Uh, I just got a 12spd deore derailleur on sale for $40. sram is going in the wrong direction...
Are we supposed to be shocked that you got a cheapo, low-end part for $40?
Still way too expensive.... Wtf
You most certainly did NOT hit the derailleur with the equivalent of a hYpErSoNIC BasEBaLL. Momentum and kinetic energy are not interchangeable terms.
But it would have been correct to say we smashed it with the equivalent momentum of a hypersonic baseball, yes? Do you say that because the implication was that it was that it was the same amount of energy as a hypersonic baseball?
- Dan P.
@@FanatikBikeCo I mean, yea it’s equally useless as saying it could withstand the momentum of a cruise ship traveling at something like 0.00001 m/s. The impact strength of a part is not at all represented by the change in momentum it can withstand. The issue is due to force being equivalent to the time rate of change of momentum. In the case of hitting it with a hypersonic baseball, the impact duration is so extremely fast that the force is enormous. In the laughable counter example, the impact with a barely moving cruise ship would take an eternity allowing for a low impact force across a long duration.
Please see the Smarter Every Day UA-cam channel to see the immense destruction of a 1000mph baseball. Fanatik is one of my favorite biking retailers, I just don’t like the massively misunderstood physics. I wouldn't comment if it wasn't egregious. The AXS derailleur is awesome, it doesn't need the extreme exaggeration, even 134 mph baseball would destroy it, to sell it to many riders.
@@brandonb6164 Thanks for taking the time to better explain, and for sharing Smarter Every Day's video-that's pretty wild. That claim did always seem too insane to be true. I don't completely understand what you're saying, but I'll keep digging. James spent a good amount of time trying to figure out how to best represent what our pendulum was doing with a real world comparison, I'll talk with him about how it could be done more appropriately. Thanks for watching our videos, and my apologies for the misrepresentation; it was our intent to be as accurate as we could with our janky set up. Once I have a better understanding of what you're saying I'll update the video descriptions with a clarification.

@@FanatikBikeCo That’s such a nice response, I really respect that. I bet that attitude has helped contribute to the success of Fanatik. Looking forward to seeing more content from you guys.
$2000 for a drivetrain is incredibly ridiculous. Used AXS for about a year. Went back to cable GX/XO combo and have not missed AXS at all.
This one is almost half that cost, $1,099.

That said, the GX/X0 combo is what I typically run, and it does work great.

Yess i think i gonna Go Back too. What was Ur Point going Back? For me ITS the weak Clutch in the gx ( should have gone for x01).
Calling a coating expensive is pretty funny. These "coatings" like hard anodize, anodize, TiN, electrolitic, electroless, DLC, Kashima coat... whatever.... there should be nearly 0 price difference between any of the coatings. One might be $100, and one might be $200 (as an extreme example) but companies that do surface treatments charge for BATCHES of... 100... 1000 or more? whatever. So $200/100 parts = $2 dollars they paid for that "coating" per part. If their batch was 1000 parts (which is a tiny batch, they paid 20cents!) Just because its desirable and people pay extra for SHINY is all it is.
Now if you want to have 1 done... its full price but that is never the case with mass prod. parts.
All that effort to try to shift as good as Shimano XT😂
I didn't realize how heavy the new Transmission derailleur and cassette were. Combined they are 332g (X0) or 513g (GX) more than the X01 11 speed! Thats nearly a pound more unsprung mass on the rear wheel compromising your suspension performance and wearing you out. No thanks.
Okay
Hmmm, I'm getting smaller differences. Comparing GX mechanical to GX Transmission, only looking at derailleur and cassette, I got a 200 gram difference.
Here's the weights I'm using.
Mechanical:

Transmission:

I totally agree with your point, but it doesn't seem as dramatic as what you found.
- Dan P.
BTW all the weights on our website are determined in-house.
The X01 Transmission cassette is 110g more than the 11-speed X01. The derailleur is 216g more.
That being said, I doubt you're good enough of a rider to notice any difference. You'll notice more of a difference in the 52 tooth upper gear.
Never liked Sram and Most of All
I Hate Electronics.
even if it will trickle down to $50
i still dont want Electronic transmission on my Bike period
All shills only hitting on the upper part of the derailleur instead of the lower part which is the second most likely part to bend after the derailleur hanger of old, ridiculous pointless crap testing just for marketing.
The GX just looks so bad though. Stick with normal AXS. No reason not too.
These new transmissions look just like derailleurs.
So now we have cockpits and transmissions on bikes.
Guess we need to call our legs power plants or something.
Please stop bike industry
Don't forget that snacks are fuel
Yup... I hit the derailleur arm on a rock and it broke very quickly. Back to Shimano XTR as it's equally as durable. When you brake your derailleur you brake it at the cage and never at the body. So why make the body beefier and leave the arm as weak as before (and more more expensive)? Also, warranty wouldn't know about such things (and yes, there are already more broken cages out there than I can count) because people just have to buy a new one and cannot file a warranty claim on such occasions. Yes, you do have scuffs on the derailleur cage but it never brakes either on the old derailleurs. It's the cage that's the weakest point and also, sometimes you hit the cage and the dropout bends. Get a new one for 15$ and you're good to go. This is just false claims. The transmission isn't more durable, just way more expensive.
Those GX cranks look butt ugly. The colour makes it stand out like a pimple and the logo on it looks like an afterthought.
Too heavy and expensive and really I think they've dropped the ball with this one
When you compare all parts involved it’s actually not that much heavier. Especially if you stick with carbon eagle cranks and a wolf tooth chainring
Electric motors and Bluetooth. I miss the old days when there was a difference between bikes and moto's. I think things have gone too far.
Can you should me which moto has a derailleur and 12-speeds? Thanks.
No, but I can show you a pedal assist bike that now uses a sequential gearbox which has been technology used in motorcycling for 50+ years.
The point is options. You don’t have to do it. Companies want to innovate. They can’t sell the same thing over and over forever.
show mw the inside of your seat stays after a year and tell me if your frame manufacture will cover the damage from the shitty drivetrain. SRAM is dodger crap.
Are you saying there will be too much chain slap on the seat stay?
More refined for less money... Oh wait, it's clickbait. Nevermind.
How so? That's what the whole video was about. Battery is tucked away, smaller motor, durability looks to be the same, all for $500 less. Not refinements?

I am infinitely more likely to give this a shot now that its not $273826 for the system.
