[@MrBjorntsc]

The groupset weights are (grams): NX: 2049 GX: 1742 XO1: 1478 XX1: 1413 NX - GX = 307 NX - XO1 = 571 NX - XX1 = 636 Now look at cost: NX: $380 GX: $510 XO1: $1252 XX1: $1466 The difference in the NX and GX derailluer and cassette is 214grams. That is a lot of extra weight on the rear wheel of the bike. The total weight difference between NX and GX is 307grams for $130. Choosing GX over NX is probably the best cost vs performance you can do other than tires. Other upgrades are far more expensive. If you want to have a better riding bike, buy an aluminum frame and spec it better. The difference between entry level and mid level component quality across the board is very notable. The only problem is if your hub is not compatible with an XD driver as mentioned in the video.

[@callumyoung7785]

I disagree I think a 100 quid brand X dropper is the best cost Vs performance or maybe grips

[@MrBjorntsc]

@@callumyoung7785 kind of assumed droppers are a given. If you are riding trails without one, definitely buy one before almost anything upgrade related. No experience with brand x personally. Do you think they are pretty good?

You shouldn't worry about groupset prices. With Sram, you should be putting together drivetrains using low or high end parts where they're needed. Just sayin

[@pyakpepyak]

Could you explain how much these saved grammes give you in terms of performance of the bike? It's nothing compared to the rider weight and also the body weight can vary by a bigger amount during the day.

Get X01 Derailleur, the NX and GX cages like to twist as they are steel. X01 is alloy and much more rigid. Get GX shifter, its the same price as the NX. Get GX cassette if you have XD driver, otherwise get NX cassette Get NX crankset

Id change it to GX crankset because its made from 7000 series aluminium, while NX is 6000

[@aaronwaterman6982]

@@uwu_demon5494 I work in an aluminum mill.. Actually the 6000series is harder to setup and treat after hardening process ..the 7000 series may have slightly more strength..but much easier to process..thats why I've always wondered why they charge more for the easier 7000 series?

[@uwu_demon5494]

@@aaronwaterman6982 Oh, thats interesting! I’ve always been under the impression that 7000 series aluminium is more difficult to machine. None the less, if you compare the GX to NX, you can see that the GX is more refined. Maybe the raw material is simply more expensive.

[@flubbablubba123]

I agree with you on most points but in generall, steel is also always an alloy. Pure steel being iron and carbon would rust if not but into an alloy with other elements. That being said, alluminum alloys are roughly a third of the weight (or density) of steel but also only halfe as strong (lover yield strength). Therefore, I would doubt that the X01 is actually more robust than a steel GX.

[@davidwales9657]

@@flubbablubba123 as the alloy is a third the weight, would they not just use 3 times as much material to make up the same weight, and 1.5x as strong?

I had to upgrade from OEM SX and GX in the long run, going up to GX and the DUB crankset makes more sense. The GX derailleur and shifter have been a dream. The crank is next.

[@techdeezout9201]

I switched up the nx derailleur, shifter, and rear cassette with GX. The truvativ descendant crank is actually a gx crank just powder coated and labeled descendent. I have the nx crank and shifter as a back-up.

[@thomasandrews8033]

Very nice review/comparison! I agree with you on the 2 X drivetrain, I like them also.

[@JPDC624]

Installed the NX system on my 2019 Trek Marlin 7. It took time to get it dialed in but now it works GREAT. Make sure you align the derailleur pulleys slightly outside of the smallest cog, and dead on for the largest gear. Also, the barrel adjuster: before clamping down on the cable at the derailleur, on the shifter make sure you tighten the barrel adjuster all the way down and THEN open it two full turns, then clamp the cable.

[@Jacob99174]

Did you need to change the hanger? Or could you use the stock hanger for the derailleur?

[@TrailBreaker]

I’ve had NX and GX. The NX was up to 42 and shifted smoother than my 10-50 gx. Zero issues on NX over 2 years. GX awesome but needs more fine tune adjustments than NX. Great value for anyone looking at a “lower” level model.

[@RobBastien]

Man! I learn so much from your channel. Really enjoyed this one.

[@dimsoneill]

Thanks mate, great comparison and review. Have NX on my new bike so I think I will be very happy.

[@Dude-Smellmyhelmet]

Only if you are a weekend warrior. NX will fail way before GX will. Just replace with GX as parts fail.

[@QQQ80804]

Would love to see a comparison between the SX and NX. The SX is being put on a lot of mid-level bikes this season so many would be interested.

[@Fred_the_1996]

Basically the same but a tad heavier

[@uwu_demon5494]

SX is pretty trash, it works OK, but when something breaks, I wouldnt waste my money on SX, if I wanted something cheap, Id put Shimano deore 12s stuff on there instead. You can mix and match them, so I wouldnt be worried

[@YourDudeNess1988]

best thing about the nx cassette is clearly that you get replacment parts for 11-13-15 tooth sprockets. easily the first ones to wear out for me in the northern flatlands. In that case it did not matter whether i drove a xx1, gx or nx cassette. they were all done after 3000-4000km . however on the xx1 this means 400€ lost in scrap, gx around 130€ in scrap, on the nx it's just 25€ to replace the defect parts. the nx cassette combined with the gx groupset has by far the best value for me.

[@coldaleonthefrontporch6748]

I had an SX derailleur come apart after 300 miles. The 2022 replacement looked like an unlabeled NX, same pulley system and less plastic than the original SX derailleur. The new derailleur used M4 screws for the limit and B screw, the original's screws were basically sheet metal screws.

[@digorna]

I noted there is a difference in the lower pulley cover: it is bigger on NX. Maybe new GX will also come with it (as the new wifi group). This actually solves (or at least helps) the problem of the chain going out of the lower pulley and end up breaking the derailleur (many cases reported).

[@seanb6691]

my bike came spec with NX, after just 9 months some of it's parts have started to disintegrate. ripped apart the derailleur and upgraded to GX, same goes for the shifter i snapped the lever and upgraded to GX for the metal lever. worth going GX for the longevity

[@FillyDing]

For the GX DUB crankset the non drive side also has the spindle!

They brought out a 10-52T GX cassette, which means you need to use the GX derailleur which is 52T compatible, don't think the NX is.

[@btupzqo6971]

I came across it while contemplating whether to buy a bike with either the nx or the gx. I watched this video all without korean subtitles to my study English. I could clearly understanding all you explained. Thank you very much ^ ^

[@SKAMUSICFEVER]

Very clear explanation, thanks!

[@LukasEkers]

I had a chance to test out both and here is my take. The NX cassette is considerably heavier, but that's not a big problem. The main issues are quality of the sifter and the derailleur. The shifter lever is made of plastic which can break quite easily if you shift too hard by accident or if you crash, and the pivots on the NX seem to develop quite a bit of play quite quickly. The GX on the other hand offers practically the same quality as their X01 and XX1 counterparts except for being slightly heavier and slightly lower service life on the chain. I feel like the GX is the right balance between cost and quality in the long run.

[@sebastianjost]

I really like my new gx groupset but if I ever have to replace the cassette I will buy a Microspline hub and an slx cassette instead. The GX cassette is so much more expensive. GX cassette: ~140€ SLX Cassette: ~65€ Micro Spline Freehub: ~ 50€ Of course GX is lighter but at twice the price, that's not worth it to me

[@LukasEkers]

Sebastian Jost Yeah shimmano seems to be a good alternative right now

[@chrisbennett5796]

You refer to XX1 for the high end comparison but never mention X01, which is almost the same, but without the bling. It is quite a bit cheaper than XX1 though. On the rear derailleurs, did you notice that the GX had removable pins for servicing, but the NX was riveted together? Not everybody will keep their bike long enough to need to dismantle the derailleur, but personally I I have a problem with anything that can't be fixed. What about chain materials etc. are they the same? I do think you get what you pay for and I would prefer to save for GX. The different free hub compatibility is an interesting one though, that will influence decisions if upgrading, I'm sure.

[@mdhdhair]

Great review! Thanks for your opinion!! Good info!

[@JoJo-yr6io]

I bought a 2022 status 140 it came with a full nx group set. After using it as is for awhile I first upgraded the shifter to x01. Big improvement with shifting feel much more crisp. Then I wanted the 520 range of the gx cassette so I had to purchase a bontranger comp line 30 rear rim (cheapest option to get XD hub) and then a gx cassette, because the nx cassette uses the old style hg hub driver, which will be on the rim of your budget nx spec Mbike.. I also purchased a xx1 oil slick chain because the nx chain got rough after a couple months of riding out in Santa Cruz with regular cleaning and lubrication still..(could of got a Gx that preforms prob 95 prescient as good but the xx1 was 40 bucks more so what the heck). I just recently purchased a gx carbon crank set to save on some rotating mass climbing up them hills. long story short... If your not catching where I'm going, spend the extra thousand bucks and buy a Gx equipped bike. If I would have done this I would of saved time and money, in the long run. But on the positive side of things, you will learn how to work on your bike and install all of this cool stuff you upgrade eventually, through watching KZbin videos and reading manuals. Because as you will learn fast after one trip to a bike shop they charge for everything and just having them work on your bike will add up in itself to hundreds of dollars. I still will go to a bike shop for wheel spoke straitening. But learning how to do 99% of the adjustments and work on your own will be priceless in the long run journey of fun shredding out on the trails. Buy GX period.

[@cybrsrce]

Before NX Eagle was available I went GX with a Sunrace CSMZ90 11-50t. At the time it was $70 (US) and is actually 26G lighter than the NX cassette. Sunrace 11-13-15-17-19-21-24-28-32-36-42-50 vs NX 11-13-15-17-19-22-25-28-32-36-42-50 if anybody was interested.

[@StraightLine_MTB]

One thing I found with the NX vs GX is the NX rear derailleur was floppy and make the bike loud. I warrantied it but the new one had the same issue. GX never had that issue otherwise NX was fine and shifted nicely.

Just wanted to let you know that I just upgraded from the SX to the GX rear derailleur and holy crap what a difference.

I love my 10t and use it a lot. I'd happily pay a bit more for 500% gear range. If I could get NX with XD driver and 10-50t I'd pay the extra, but then I way as well shave some more weight and go GX.

I have the complete Nx setup on my Treck Roscoe 8 2019, you will be spinning your legs on down hill descents, I never had that problem with my old 3×8 setup back in the day, I'm not sure if it's all of sram groupsets, what you need is a much bigger chain ring than say a 30 or 32 tooth, but then like you said, that would ruin your up hill shifting, that is a excellent question!! In my opinion 1×12 is good for uphill, but horrible if you really want to crank down hill, because the tiny chain, just can't seem to keep up!🤔 I wish someone would answer your question!! And if any parts are worth upgrading from GX to XX1 or XO, besides the weight factor! I would really like to know also, because I'm about to get a Santacruz Carbon Chameleon S Plus with a Gx Groupset....

[@fredsanguino703]

Recently I bought the sram eagle nx transmmission and after the first few pedals I agree with you that this transmission needs several kilometers to work perfectly. I also agree that the 10-tooth pinion is not necessary in XC and very rarely in a marathon; unless the marathon goes through many stretches of road.

[@medicjoe79]

would you consider setting up the NX groupset with Sunrace 12 speed cassette? Understand the Sunrace is lighter.

Nice review. All the Sram 1by systems work great. I’m still running a GX 1by 11. Love it. I do not agree about doubles what so ever. I don’t like them. Never have. But I am a old single speeder at heart, so I might be a little biased. 1by systems opened the door for bike designers to tweak rear suspension designs for the better, unobstructed by a stupid front derailer that always drops the chain, or jams, or chain-sucks in the mud, or... Uhg, ok, I’ll stop now. 1by systems also gives you a great place on the bars for a dropper post lever. Thanx for posting you video.

[@davidwales9657]

Get an X01 derailleur

[@scherzo0o]

Well, I would. And not because of the weight. But because with 10 teeth on that smallest cog, you can put a 30 teeth front ring, and you have a 30 to 50 ratio for uphils. Preserving the same 3x ratio for the smallest cog leads you to a 33 to 50 (realistically, 34 to 50, since I haven't found a 33teeth ring)... which is less that 1.5 ratio for climbing. Now I have a complete GX line, with oval 34 front ring from Garbaruk, and it pays off. It's true, I'm riding a lot on long flat surfices, and that 34 to 10 helps a lot.

[@SeaCowsBeatLobsters]

Good point

[@jsv438]

I really want the use of the 10 cog. I WAS going to go oval, but I went from a 30t chainring to a 32t Absoluteblack and now have no desire to try the oval. Now w/the 32t I get more out of my 10, WOULD like a 10-52t instead of the 10-50 I have--next cassette I'll do that. ~JSV

[@NDemanuele1]

Interesting video, I really appreciate it! I just bought a Ripmo, NX build. I'm wondering what do you think about the durability/reliability of the NX compared to other drivetrains? Thanks

[@reallybigphilly]

I'm not SickBiker... but have a full NX drivetrain (with the exception of a GX chainring up front) and it lasted 3500km before I swapped out the chain and cassette (also did the front chainring to be thorough but I dont think this was absolutely needed). After all this distance I did get an issue with my NX rear derailleur, but according to my local bike shop this is due to a manufacturing error so it will be replaced under warranty. I decided to pay the delta and upgrade to a GX derailleur for a wee bit of weight savings and slightly (!) smoother shifting, and because I can afford said delta, and I am a bit of a nerd... but until the manufacturing error became apparent I never really had an issue with the derailleur's performance. I swapped the chain for a KMC X12 for the looks (black and chrome links) and the cassette for a SunRace CSMZ90 for the looks as well as the weight though.

[@Svenmpa]

I am changing from NX to GX because the weight of the cassette. And by saying that, I am changing just the cassette. And that is because of the weight of the NX cassette. GX is like 25% lighter where it matters, on the wheel and also on the wheel and therefore unsprung weight ( riding FS bike). Yes I have to change the driver body of the hub, but that is like 60€.

[@tduic]

Then it's best to buy Sunrace 11-50 cassette, becasue it's way cheaper than GX and NX, it's solid, and it weighs 524 grams which is 100g lighter than NX. And you don't need a XD driver then.

[@cannondany]

Yup, consider the Sunrace, though the Eagle cassette provides great shifting performance.

[@Dude-Smellmyhelmet]

@@tduic It works but it's not best to buy the Sunrace. An Eagle cassette shifts much smoother. I'm not sure about anyone else but I wore a sunrace cassette out really quick too

[@JorgeGutierrez-no1lr]

Excelent review! I am suscribing right now.

[@JonFairhurst]

I bought an XC bike with NX components. When I upgraded the wheels, I went with an XD free hub and 10-50 X01 cassette. The weight savings is significant and the 10T sprocket is great on pavement. It’s a 10% jump, which is significant, and with a 34T ring, I no longer spin out when riding to and from my local trails. The NX shifter and derailleur work great. (And AXS is crazy expensive.) If I upgrade the crank, it would be with a Raceface carbon crank and an oval ring, rather than XX1 or X01.

[@KapitanPisoar1]

I ride the 1x11 X01 and I have never dropped the chain while riding in 4 seasons I am using it. Most reliable drivetrain I have ever used.

[@bigfootandbananaman4746]

KapitanPisoar1 I ride a 1x10 xo drivetrain and I have also never dropped my chain

[@user-mh7xb7dt4f]

I have to say nx is terrible I work in a bike shop and I've seen everything from worn out mech pivots after only a few 100 miles, cassette cogs folding with shifting under load and shifters just outright failing. They almost never work properly from the factory and when setup correctly with srams b tension tool and cable tension is correct it never wants to shift properly in gears 1 to 3. Srams gx is the sweet spot for price to performance and reliability and every re occurring issue we deal with on nx is pretty much just solved by swapping parts for gx and the updated gx this year is nicer also definitely worth the extra cost.

[@SeaCowsBeatLobsters]

THIS source: am mechanic

[@jsv438]

AGREE! The NX is really not for pro quality or high-end mountain bikes. For a little more ANY bike gets a serious upgrade going to GX. ~JSV

[@drcobayo1]

What’s your opinion about mixing the slx cassette (with micro spline of course), Shimano chain (I think sram is a little more wide) and shifter/derailleur Nx (o other sram). I change the rear hub of my brand new Cannondale Fsi carbon 5, because the quality of the rear hub (formula ain’t good), and take the opportunity to upgrade to a shimano slx cassette because the price of a gx cassette vs the slx. For me works just as good, maybe best of two worlds, but I’m sure you have more knowledge than me. Thanks!!!

[@Sphoxros]

Glad I went with an E*13 TRS+ cassette, paired with a X1 shifter and derailleur :). Feels great, looks great, and just works.

[@zacharysmiles1308]

Ok I still run a 2x drive train on my 29er hardtail, in long gravel or marathon kind. It still seems like there are gaps that would trash my legs on climbs. Am I crazy in not wanting to pay more money for less gears???

[@Asthbendriel]

no, you're fine. I also had a 2x system until my brother in law's drivetrain died recently and I passed him my 2x drivetrain and bought a 1x to check it out. 1x works fine, it's easier to clean and easier to pedal standing without switching gears that much but man, at least a few times in our weekend rides I do miss the gear range of 2x, since we do 40-60km natural trail rides and we climb quite a bit, always between 1000 - 1500 meters of elevation gain and even a 2x9 with a wide range cassette has an easier gear to climb than 1x11 or 1x12 with 11-50T cassette, and installing a 30T chainring makes the whole system too slow.

[@Jabba1625]

Same, I miss the 2x drivetrain and if I'd not brought a trail/bush basher I would gut the 1x as soon as it died, then go back to the 2x. I think double chainrings still have a place on XC bikes, just a personal opinion, not forcing that Idealogy

[@sebastianjost]

I have recently bought a new bike switching from 3x9 to 1x12. Due to Chainline I never used more than 14-16 different gearing ratios on my 3x9 drivetrain so I don't really miss anything. You do need the 10T cog in the rear though. Otherwise the system would be to slow for me as I love in quite a flat area and have to ride 15km to get to any mountains or even hills. On a road/gravel bike I definitely prefer the close gearing range of 2x systems and I can definitely see why some want that on their MTB too. So I'm glad Shimano decided to still offer 2x with their new 12 speed drivetrains

[@flubbablubba123]

Nice detailed video - I like it. I am running a NX Drivetrain on a Canyon Strive (Enduro) and I actually have some issues with the NX cassette. The fact that the casette is not one piece makes the individual gears come loose and cause rough shifts and annoying clicking sounds. Re-torquing the cassette with the specified torque is not helping. Using more torque may cause the freehub to slip through which is obviously bad(!!!). Only a complete dissasembly of the cassette, thorough cleaining and reassembly could get rid of the issue for a certain time. I had to do this twice over 1800km of riding so far. Since I do ride some rougher stuff and bike-park laps, this may explain why this happens that often. I would gladly upgrade to the 1-piece GX cassette but the additional obstacle of having to change my freehub body is annoying. Also this is where clearly NOT all eagle components are fully compatible / interchangable right away. This as far as I know is the one exception to the rule I guess. So my advice is: If you are into occasional bike park visits and riding some rougher stuff, consider going at least with the GX cassette right away. Also the 10-tooth gear helps in fast park sections and the entire cassette being one piece is just better overall. If I get a new bike, I will make sure it has at least a GX cassette right away.

I'm in UK and looked at the santa cruz bronson £5000 and it got a nx drive train on it want the bike but that has put me off don't want spend that much on a bike then start upgrading a drive train think wait till next year's model see if it changes surely they could of put at least gx on that bronson

[@flubbablubba123]

@@Macca78 oh wow I would say you absolutely dodged a bullet there. For such a price I would expect it to come with a GX casette and hence XD drive body standard.. My bike was about 2200€ so it is somewhat understandable to have a low end drive train installed..

Great video, bro! Tks!

[@oscarjaviersolanosantana4774]

thanks a lot, bro wide clear for further desitions

[@51249ca]

Gimme a better fork/shock combo with NX over “cheaper” suspension with GX, but that doesn’t exist with bike manufacturers unfortunately

[@mrvwbug4423]

A lot of OEM hubs can be converted over to XD pretty easily these days, so you can upgrade to GX when the NX wears out, or you get tired of spinning out at under 20mph.

Danny. I live and work here in Poland, as an American defense contractor. I am in Miroslawiec, and bought a Trek Excalibur 8 with SRAM SX, 1x12...it never worked. Chain slipped under any tension, I could never stand out of the saddle, and I was constantly struggling to find the gear. I bought it in Pila. I bought the bike to use everyday for commuting and fitness, for about 50 KM per day. I bought SLX, then the cheap pedal broke at speed down hill, I crashed, and damaged my SLX deraillure. I am thinking of going back to SRAM...Should I get the NX in 1x12? Thank you and love your channel.

[@rolux4853]

Get GX! I don’t know why he has a grudge against them. NX is useless to me, since it doesn’t work with the amazing XD Freehub.

[@bryanesmith8739]

@@rolux4853 Except the guy you are replying to probably has a Shimano freehub, so he would need NX.

[@azmtbiker9267]

My entire drivetrain is GX except for cassette (11-50 NX). I have just over 3,000 miles on my 16 mo old 2019 TREK Fuel EX9.7 and haven't had a single drive train failure (drivetrain is 1 x 12). Made the first very slight adjustment on the rear derailleur about a month ago (I think due to cable stretch)... On a scale of 1 to 10 (1 being easy paved commuting, 10 being balls to the wall DH and sending everything) I'm probably a 7 in ride style. Have replaced the OEM chain, a GX chain, and about to put on another GX chain when it comes in next week (so averaging one chain per 1k miles). I also have a back up rear wheel (same as OEM) with a 11-50 NX cassette that gets rotated in when I break a spoke. Bottom line, spend the little bit of extra for the GX components.

[@serhijmudrak7780]

Hi, thanks for a good review. I have a question about material of a cassette and chainring, is there applied the same material on GX and NX chainrings or GX and NX cassette?, if the answer is yes it would significantly affect a durability of those parts.

[@jorgegomes1023]

Thanks, fantastic review.

[@roobendoraisamy]

Thanks, i got an NX.

[@turtlerumble7357]

I use the NX 1X12 and it works great. It is robust and very precise but my use is moderate and I do not compete. The additional weight is not a problem, on the contrary since my practice of mountain biking is also to strengthen my muscles. I think the best system is the one that fits the use we make of it. Whoever absolutely wants to make time will move more towards a lighter system. As for my experience, I have used for years shimano and I prefer eagle but the most important is to have a diverse offer to find what corresponds to his expectations. The paradise of one can be hell for others ...

[@Jabba1625]

I like my NX eagle drivetrain but miss Shimano, although I absolutely hate Avid/SRAM brakes. The weight is such a beat up, unless you race and are rich or well off, I always refer people to the fact, how did bikes weigh 15 -20years

[@morganjenkins4924]

Do you know if I could add this to a 10 speed hub?

[@TonchoTonev]

@@morganjenkins4924 yes you can

[@sebastianjost]

@@Jabba1625 you can mix SRAM and Shimano 12 speed components in any way you want. They are completely compatible as many tests have proven. So whenever something on my new GX drivetrain breaks, I'll probably replace it with an Shimano XT or SLX part. Most Shimano parts are also cheaper.

[@Jabba1625]

@@sebastianjost nice to know, I'll wait for my NX to die then try it, thanks for that bro

[@bombastic5499]

So I have a question, I have a XO1 NOT EAGLE with gx NOT EAGLE cranks, is the gx better?

[@Legacy40k]

Thanks for this video. I've just ordered a new full suspension bike, and it comes with NX - was wondering what my options were for upgrading it in the future. Sounds like it's worth it to skip up to XO if I'm going to upgrade parts rather than just GX. The main issue is if I want to upgrade the cassette - which requires a whole wheel/hub change. But it could be run with the NX cassette and XO parts if I really wanted.

[@TCK12310]

either go xo or shimano xt. I'm chucking my xo and going over to shimano xt with a dt 350 hub soon

[@diegorojas9811]

I have NX and runs super smooth 👌🏻

[@jadeloff5557]

I'm just going to say after riding on both these group sets and racing multiple enduro races one both I would rather pay the extra for GX I think it's all just more sturdy feeling

[@lucadobrin3850]

Fun fact I bought my bike in 2019 with sram nx groupset and the derailir started to move around and won’t tighten and this happend to my casset asweel but on gx this dosnt happen

[@benjaminblum1172]

what should i tell, my combination is a nx dub crank, an nx 12speed pinion for my hg freewhell hub, a nx shifter, a gx rear deraillour and a gx chain.

[@juliastrasser3766]

this video helped me a lot. thx

[@ThePep678]

The biggest difference is the smallest cog being 10 instead of 11 teeth. If you are racing this is a big deal. Riding a 30 tooth on gx is equivalent to riding a 33 tooth on the front with nx. So your top speed is greatly affected by running nx. It really stinks to be running a 34 in the front and spinning under 30 mph with NX. If your all about fun NX is an amazing value and groupset especially if already have a shimano freehub.

[@l0gphroe]

...or you could just purchase it with a 38 tooth chainring :-) It comes with the following options 30, 32, 34, 36 and 38.

[@JohnSmith-qv6hp]

Biking down firetracks you need low gearing my 3x10 never failed me there climbed as good as my 1x12 nx but much better top speed

[@Iheartdgd]

Gx is the best bang for buck groupset you can get for a mountain bike as far as I’m concerned..that’s all I run at the moment is Sram Gx

[@captaintraction4024]

Your a genius! Btw, same

[@Dude-Smellmyhelmet]

Try putting an X0 shifter in the mix w GX derailleur.... I rarely damage a shifter so I figured I'd go a step higher on the shifter and I'm glad I did. So smooth and snappy

[@captaintraction4024]

I just put an xx1 chain on mine, made a huge difference! Here is a list of what stuff you will notice highest to lowest difference: 1 cassette 2 chain 3 shifter 4 derailleur

if i want to upgrade from nx to gx, do I have to buy new wheels as well?

[@frankiemazzei8882]

Think you just need a new driver body or hub

[@AubreyOutside]

For the cassette only - You do if your rear wheel hub cannot take XD. If your wheel is XD compatible or already has XD you’re good to go. Everything else is cross compatible

Hack we did on our shimano free hub wheelset. We bought Gx shifter Gx crank Gx RD Gx chain NX cassette Perfect upgrade for people who want to save some $

[@alpd7638]

I would recommend going for the X1 chain

[@Jonilink]

I literally JUST bought those parts today minus the cranks cost me $270 at my lbs.

[@drmoynihan]

Jeffrey, My new Commensal Meta TR 29 is arriving in 2 weeks. When I bought it I asked about an upgrade from NX to GX, but they told me that it was simply sold as it was. To get upgraded to GX would have cost me about $1,000 more (extra stuff that I didn't care about upgrading). It comes with the GX Crank, I am upgrading to a SRAM twist/wrist shifter (thumb injury), and I am wondering if I would find upgrading from the stock NX to GX Derailleur for $125.00 would be worth it. I would be leaving the NX Cassette on it. What do you think? Is there any real difference between the NX and the GX Derailleurs? And is the GX Chain really any better than the NX. Maybe I'd just upgrade to GX and save NX Chain as spare. P.S. I know that upgrading to a full GX from NX would include new wheel/hub, etc - so I will only go that route if I really want 10-50, rather than 11-50.

[@Robinators]

I have sram nx 1x11, next derailleur im gonna buy GX, because its more robust. Same goes for shifter( or some XO stuff, if i can get them used and cheap). not planning to go 12spd, because 11 is still cheaper. And probably switch out those NX cranks for some shimano slx or XT, because of cheaper chainrings! :D Cheers.

[@cannondany]

Yeah. The NX Eagle became quite affordable, but those older groupsets are now even cheaper. Agree.

[@Dude-Smellmyhelmet]

Yes. GX derailleur and X0 shifter. Great combo

[@jimheitzman]

I have a set of Rival 1x11 brifters and an SX 1x12 RD, can I use an NX cassette with these?
