- Hack to fix the play by using the XX1 / X01 SRAM Eagle B-bolt kit on the NX or GX 12 speed derailleur. The upgraded kit uses a bolt with a bushing rather than just a solid bolt and should last longer.

Wow, this totally fixed the cage wobble on my GX derailleur. And as an FYI, the part number for XX/XO AXS B-bolt kits works as well. The mechanical XX/XO kits were not available, so I gambled on the AXS, as that was all I could find. No issues whatsoever. Thanks!
Thanks for the good info 👍
So XX/XO AXS can be mounted to GX AXS, right?
I just ordered an X01 AXS bolt kit (11.7518.092.001) and it did not fit my mechanical GX Eagle lunar derailleur properly. The bushing is a bit wider than the derailleur itself (like 0.5-1mm), so even with the bolt tightened down, I could slide the derailleur side to side. It's a bit of a hack, but I filed the bushing down a bit and it fits fine now.
Brother 1 question. Apreciate ur work, why not grease the bushing and the oring seals ? 😀
B-Bolt kit works like a charm!
Hey Tony! The upgrade got rid of all play. Re-set my low/high/indexing after installation. Major difference. My shifting is crisper and overall drivetrain quieter! Thanx again for the assist!
Glad to hear! Hopefully it will stand the test of time 👍
@@TonyHob it stands the test of time. Over 1500 miles on my GX since the bolt upgrade and the derailleur doesn't have any play whatsoever.
My wife, who's a fairly conservative rider, wore out the mounting bolt on her NX Eagle within 8 months to the point where shifting could no longer be dialed in across the entire cassette range. I replaced her B-bolt the same time I did my GX (or the other way around - my shifting was sloppy but tolerable, but I researched the problem when we considered trashing her derailleur). She doesn't ride as much as I do, maybe 1/3, but same outcome. Zero play.
@@mediasucks Is the upgrade process on the GX the same as the NX in the video? I'm planning on getting a second hand NX derailleur to upgrade an older 2x10 lender bike and have GX on my personal bike and was thinking of upgrading b bolt on both of them at the same time.
@@plproductions8887 Yes, I actually have it on my GX now
Thank you for this awesome fix! I can confirm it also works on a 11 speed NX.
Awesome, thanks for the information 👍
Can you share which kit you purchased for your 11 speed NX?
Dude…thank you, so much! This seriously fixed my whole life!
This is a really great hack to upgrade an NX, just completed it and it feels really solid. No movement at all from the bolt pivot. Thanks for the great tip!
Glad it helped. Mine still feels solid and is shifting great!
Thank you Tony, I could not figure out why my shifting was crap for ages. Swapping out the bolt kit is far cheaper than my plan to change the derailleur completely.
Glad it helped!
Used this bolt kit for SRAM Apex (11 speed). No issues so far. Thanks for the video
Thank you for answering my first question. My other question is does the kit lock the derailleur lock the mounting plate in the correct position?
@@michaelgurd7477 I see no difference with "native" apex bolt kit.
At first I was sceptical to this, I didn't thought that it can make a difference. But I decided to try as it's an inexpensive upgrade. After installing, the derailleur required some adjustment on b screw and limit screws, but now it shifts significantly better!
Glad it worked out
Yup - Another satisfied hackstomer . . . . Worked perfectly and no more wiggle slop on a GX I just finished rebuilding. Thanks !
Appreciate the videos. I took off my GX derailleur which has been working fine to upgrade to the AXS GX kit. The GX AXS derailleur also uses this new style of bushing so that’s nice it has the upgraded piece (it better for an expensive drivetrain!). When taking off my original lunar GX mech the split ring came out along with some other washer. I thought this was some metal shard that sheared off the bolt and tossed it. Oops so I may need to buy the $10 B-bolt GX kit or spend for the $30 for xx1 bushing kit if I ever sell the GX mech or go back to it..
Good to know thanks, was just wondering whether to fit this bolt on my GX AXS!
Thanks so much for upload this tuto, I'm having the same issue with my NX!
Oh sht. This is a beauty for sure. Thx on the lolo. I went back to 42t medium cage. These long cages are ridiculous.
They seriously need to revamp the rear mech. Its like draggin ur nut sak just on one side on 27.5
Just did this mod on my new Sram GX 12 speed derailleur after seeing your Video on this problem, Sram should just fit this across the board in my opinion. My new GX derailleur didn't last very long at all before it developed play in it, yes I ride through the Wet muddy UK winter, which doesn't help any of the Drivetrain components, and yes I do maintain my Bikes.
Hard to find stock at the moment of this part, I ended up buying one from the US which made it even more expensive than it should have been.
Thanks for your video, it helped me out 👍👍
Just did this on my NX ... BOOM works like a dream
Older video but it was just what I was looking for. My gx axs is old and warn so I bolt this bolt kit and was wondering how it came apart! Thanks for the info!
@@panhandlemtb4308 glad it helped!
Thanks. Didn't make the upgrade but showded me how the GX version actually is assembled. Mine was weirdly wrong assembled 2 years (by me lol).
Glad it helped 👍
Incredible! All play gone from the bolt area. Also had to adjust my limits which really shows how much it was being pulled around before.
And if I ever break the derailleur, I can just remove the bolt and put it in the new one!!!
This worked for me as well, thank you!
The crazy thing is, the new b-bolt is pretty sloppy in the sleeve, probably worse than the original b-bolt in the derailleur body. The improvement is probably just from mashing the o-rings in there which would explain the new pivot friction. It makes me wonder if you can just jam an o-ring in the stock b-bolt assembly somewhere and get the same result.
Dude your comment helped me a lot. I bought dozens of O rings trying to fix the side play on my GX eagle. It works so well. Just replace the original wavy washer with a 15(outer diam) x 2(thickness) rubber O ring and the side play is completely gone.
This is great. I just did it on the sx model
thanks for the video... my NX 1x11 happened to unscrew and I lost that spacer plate. went on service and they donated me an used NX eage with bent cage... just managed to swap the plate and bolt and it seems to be working. I was asking on some FB groups and all i get was buy new derailleur... take it to service... I'm sure it would cost me at least 50 denaros on service...
Bonjour Tony ! j'avais un problème de jeu aussi sur mon X01 déjà équipé du nouveau system, j'ai trouvé en magasin un tube en alu de 12 mm ext et 10 int pour remplacer la bague qui coulisse, plus un peu de téflon de plombier pour l'étanchéité, graisser int et ext et serrer le tout, et c'est reparti pour un tour, 3.80 euros le tube, c'est beaucoup moins que 25 euros, merci pour ta vidéo et bonne continuation !! ;)
Thanks i changed the bold on my gx 12 speed derailleur and it worked like a treat. in my case i have to unbolt the derailleur when transporting the bike and the original snapring came off every time. 😂
I bet Sram hates this hack! Good job, Sir!
Thanks for the video! I got this upgrade and wasn't sure how to assemble it.
Glad it helped 👍
Just followed this as I've bought a new GX derailleur XX1 Chain and shifter to replace some SX stuff which came on my Marlin 8. I thought I do this before it all goes on the bike. Thanks
Nice remedy! So Nx rd is not a good buy as you need to upgrade it but its manageable.Thanks for this video.
A lot of people don't like the NX 12 speed group. I went with the GX on my hardtail and so far it is working very well
I have an X7 derailleur with what I assume to be a seized B bolt. I haven't found any good content addressing a fix, but even knowing that it's called a B-bolt is a ton of help. Once I get time to tinker, I'll see if I can follow along and get it off my bike!
Hope it works
Definitely worth it thanks for your video.
I have ordered for my NX derailleur SN: T26NOV20 the kit for XX1 / X01 Eagle (52T) rear derailleurs - 11.7518.098.005
Fits perfectly
I did this recently good result when on the hangar NO PLAY so maybe should stop the overshifting problem people complain about.
Hello, I upgraded my Gx bolt with this new XX1, but there is still play on it, like a big play, about 0,5mm in the bolt and makes the derailleur go offset by more than 2mm
Have you installed it on the bike? The play goes away when installed. If the play is with it installed make sure you did not miss anything.
Thanks for doing the video!!! Going to do this on my NX derailleur.
Thanks, glad it helped
Just ordered one. Thanks again.
Awesome!! Worked a treat! Sorted my shifting issues, big thumbs up from me!
Thanks 👍
The limiting plate of the NX/GX is completely flat where is slides alongside the derailleur. However, the XX1/X01 limiting plat has a curve at the end which appears to push against the derailleur when using the the larger cogs and creates a slight bow. I'm not sure if this is enough to affect long term wear, but I'm considering flattening the side of the XX1 limiting plate to prevent this. I only have an NX and GX derailleur, so I don't know if the XO1 /XX1 has a different design to accommodate this.
And i was about to order an eagle nx groupset, thanks for the heads up...
I am using an NX chain and cassette with a GX derailleur and shifter on my hardtail and it has been great!
Thanks for sharing, I need this kit for m'y NX derraileur too!
did it work?
thanks
If anyone is wondering, this mod doesn't work on SRAM Eagle SX. The limit screw plate is different and this one doesn't fit.
Thanks for the info 👍
Si yo que iba pedir uno kit para mi cambio sx ya esta comprobado que no sirve
Que lástima
Thank you!
May work on the post 2022 model
Add GX jockey wheels and you get a decent derailleur.
Is it worth coating the o rings with a layer of silicon grease? They are expensive - $38 for a bolt. Gotta love Sram.
It will probably help, on the other hand it could attract more dirt. I agree, that price for the kit is ridiculous!
Tony, is there a need for grease on the bolt? If so, how do you take it out? I just watched your video and followed through without considering this. Cheers!
if you are referring to the bolt and bushing assembly, it does not need to be taken apart and greased
@@TonyHob thanks! Not inside, but does the outside of the bushing need a bit of grease?
Just to share another findings: I have tried to use X01 DH 7-speed B-Bolt on GX Eagle and it doesn't fit. It has exactly same length, but bracket collar or bushing has to be different..
It's pretty hard to find these parts noways, everything is sold out...
Thanks for the info and update 👍
Brilliant video. Thank you.
Hi Tony, I tightened the b-bolt to 11nm (according to spec) and the derailleur can swing a little bit on it, if I tighten it to 12nm then the derailleur doesn't swing at all. Do you know if it should be tightened just enough to let it swing freely or should it be tightened fully until there is no swing at all? BTW, I'm checking this with no chain on.
Mine does not swing at all once mounted
Have you fixed this?
@@manzthatrmanz23 I left it at a point where it is not fully tight to allow a bit of swing in case it is required. No issues so far.
@@rgarzari ok thank you
Should we be greasing the b bolt inside and outside the bolt sleeve. My derailleur has endured 5 years of xc and trail riding and fear my derailleur is toast because mine still has play after the x01 b bolt upgraded. Great video, thankyou.
Hoping the grease will take up the remaining slack in the bolt assembly
@@JP1THUG I don’t think the bushing and bolt necessarily need grease but it would not hurt and could be beneficial. My only concern is that it could attract dirt.
@TonyHob hey there, I've just taken it apart and greased inner and outer sleeve and derailleur internal interface. Reassembled and there is no play now what so ever, so happy. My concern was there regarding that to but figured the grease and o ring seals together will keep that assembly water and dirt tight.. thankyou for the assembly video
NX is possible, but this bolt doesn't fit on the SX. The washer in the middle of the bolt is about 3mm longer than the width of the body of the SX B bolt hole. I cut the washer 3mm and put it on the SX.
Hi, Is that still working for you? How about B-Bolt plate?
hello tony if you install the xx1/x01 b bolt kit to a NX do i still need the wave washer you installed in your previous videos?
No, the kit includes everything you need and does not use a wave washer. It is really the best way to go
Does the b-screw have to be readjusted after changing this?
I did not have to on mine
Hello,
I have the same problem with my NXEagle Derailure and thinking about upgrading the bolt! Maybe you have been using the upgraded derailure for an year now! Want to know about your experience about it.
Thanks in advance.
It’s still working perfectly for me
Hey, love this upgrade, my derailleur’s GX, I imagine it’s plug and play as well? Can you put the link for the gold colored one please? Thanks, great video!!
It will work on both 👍
@@TonyHob Thanks Tony!!!
Great video. I see in the comments that you added a bit of grease to the outside of the bushing even though not called out in the manual. Is there any reason why you didn't add a bit of grease inside the bushing as well?
Good point. I actually did add a light coating of grease to the bushing but did not include it in the video.
Hey Tony, im thinking about trying this to fix a problem there the b plate is slipping past the little nub on the derailleur. Do you think the tab on the B plate sits higher and will fit better in the hanger?
Not sure if it will help. I am out of town so I can’t compare the two
@@TonyHob I’ll let you know my findings!
Thanks so much, SRAM is very annoying. My shifter on the handle bars is only shifting 10 out of 11 shifts now after 2 months. I've already had it apart because it was binding up and not shifting at all... I hate NX
I ended up using the NX cassette with a GX derailleur and shifter. It works really well. NX, not so much
Your issue could be a result of how the bike shop put it together. I have the NX drivetrain on my Giant Trance and have had no issues.
Hi Tony, so those kits are cross compatible? I have Sram X01 DH 7-speed. Could I use that kit on it instead?
My understanding is that they are different but I have not tried it myself
@@TonyHob Thank you
Great video. Do you know if this XX1 upgrade will improve the GX version? I noticed the GX version has exactly same parts but different model #. Not sure if the tolerances are different.
I have it on my GX 12s right now. It works great
@@TonyHob Did you notice any other improvement on the GX though? Also do you think these would be compatible with the GX AXS?
@@GokkunGuru well it shifts perfect like it should and the bolt is two piece (has a metal bushing) instead of one piece, no other benefit that I know of. No idea about the AXS
Thanks , now I know how to deal with it 😉❤
Any idea if these fit 11 speed nx derailleurs?
Dose this kit work for a 11 speed sram derailleur?
Not sure
will this fix the issues I've been seeing of NX RD's overshifting? The one skipping on cogs when upshifting to the smaller cog?
Only if it’s due to play in the mounting bolt
I find it difficult to understand why any play should develop in this bolt, as there shouldn't be any movement here (other than when you adjust b-tension of course). As far as I can see, the only reason for the derailleur to rotate around this bolt would be if the spring in the clutch assembly isn't capable of holding the chain tight, and that the entire derailleur is free to rotate backwards before the chain slack is taken up by the spring. If so, I'd say that this is a design flaw that SRAM should correct asap.
thank you for the video.. I somehow lost the o ring so I had to but new kit but its really strange there is no manual on sram website how to install it.. shoulnd you use any grease?
I put a very light coat on the outside of the bushing but edited it out because I don't know if it is even needed. The old bolt did not have any grease.
The only B-bolt kit I can find in UK is the xo1 DH 10 spd.... has anyone successfully used this version to fix shifting issues with NX derailleur?
Hi Tony! I bought a new bike in January with a GX derailleur and have been fighting it since day one. Mine has the wobble which causes it to shift like crap. I'm assuming the X01 bolt kit will work the same as the XX1 kit as both use bushings and look identical other than color of limit screws, do you know what the difference is, I'm guessing materials for weight is all. The XO1 is cheaper($24) is why I ask.
Thanks Tony this will be awesome to fix this problem!
X01 - 11.7518.080.000
XX1 - 11.7518.076.010
XX1(gold) - 11.7518.076.000
From what others have commented it works the same. I went ahead and pinned one of those comments to the top.
@@TonyHob I can confirm it works perfectly! No play whatsoever, I'm stoked! Thanks you Tony!
I got the gold. Cause I'm a pimp.
Does the xx1 x01 and x1 b bolt kit work on the sram sx eagle? Mind broke yesterday and i can’t find the right one for my derailleur.
I would think so but I don’t have an SX to confirm
Update: it doesn’t work with SX
where to order this xx1 b bolt kit?
doesnt there need to be grease between the b-bolt and the metal cup ?
I don’t think so. It’s a pivot bushing so it should be fine as is . A thin layer sure wouldn’t hurt though
I changed it. The wheel cannot be removed. The screw is stuck the derailleur. (sram nx 11s)
Hey Tony what’s this kit running for?$$$ I just bought an NX 12spd derailleur setup.
this is the one I bought: amzn.to/301rif8
Tony's Hobbies thanks I appreciate you sharing the link.
Nice video - we should use Shimano, they don’t do stuff like sram does…
After 5 rides in the wet my pulley stoped working because of dirt in the bearings and now I installed the bolt shown in this video…
Using my Shimano XT for 3 years before and didn’t have to do anything! Just works like the first day.
I have two bikes with Shimano XT drivetrains, best bang for the buck out there
So 3 years on, hows it holding up? I assume well
Continues to work so well that I hadn’t even thought about it until this comment, LOL!
Thank you for sharing!
Great video! Any idea if this would work also with SX derailleur?
I would think the dimensions are the same but don't know for sure
Hi , I tried with Sx derailleur and does not work , the screw is to big for the bolt hole in the derailleur.
Do you know what the sizes are for the; Orings, Wavy washer, and Split washer? I'm trying to find that information.... and that for posting this.
Check this video at the 2 minute mark th-cam.com/video/6oFeT0rteHc/w-d-xo.html
@@TonyHob Thanks very much on the specs, ordered the wavy washer do you have any idea what the spec is on the flat/split lock washer?
Sorry, I don’t
@@TonyHob No worries thank you for everything else.
I did this and the derailleur is really hard to move. It doesn’t move smoothly from the pivot point of the mounting bolt. When I shift up it’s really hard to press the shifter. Why could this be?
I’m not sure. Maybe others will chime in with ideas. Does it move freely with the cable disconnected? Also make sure the backing plate is in the correct position
Hi just wondering why do not have to add grease to the bushing / bolt
You can if you want. The bushing is greaseless and maintenance free as far as I know. Otherwise you would have to clean and re-grease it periodically
@@TonyHob Thanks, just picked up a GX as part of a mixed GX/NX set - have installed this bolt from new. The old bolt was showing signs of wear already despite no use
having same problem so just wondering if this is still working for people if so ill order the kit, if not change groupset , would appreciate if someone could let me know thanks
Yeah mate, works perfectly. Absolutely no play when i attached to my frame. No shifting issues that i had before.
Been using this since I made the video and still working perfect
Did this entire job… same wobble and play
@@bellamyren-2547 could be the derailleur body itself is worn.
Man, that was awesome!
I purchased the x01 and tried this and think I got the wrong one. Maybe it is for an 11 speed or something. I have play front to back on it. It does not go away after mouting it. I have a thin gap. Any clue about this? Also, I cannot get it off now no matter what I do. It is stuck on after I pushed it on. Any help would be great. The one I got is the 11.7518.080.000
It’s a different part number from the one I used (I put the link in the description) but looks about the same. You should be able to carefully pry the cap back off with a small screwdriver to remove it
@@TonyHob It was tough trying to to get it off for sure. I ended up finding a little spanner wrench from some crappy kia piece of furniture and it worked. I will return that one and get the one from the link. Wish I saw that part of your description sooner lol. Time for attempt #2
Did you grease the bushing prior to installing?
yes, a very light coat
Thanks Tony!!! Appreciate it.
worth it on the Gx Lunar?
Only if you are having problems with it
This works in the SX one?
Someone in the comments said that it worked for them. I haven’t tried it
@@TonyHob It doesn't work i read some comments saying that the hole is different! I repaired It with a bigger o-ring now it doesn't move anything!
Thanks for letting us know. I hope you find a good solution.
Would the NX b bolt fit in an XX1 derailleur?
Yes, but it would be a huge downgrade 😂
@@TonyHob 😂😂 yeah true. Well good to know just in case I can’t find the proper one. Thank you!
Hi, great advice. I installed that on my NX. Though I had one issue. At 06:35 you are installing the "hook" of the bbolt kit. At my kit that hook came in 2 parts: hook and the metallic-tooth-washer that was bit wider than the socket. On your movie the washer is already in place (socket). Did yours came in parts and if so, how did you manage to join them? Finally I have just mount the the derailleur bolt with the hanger and by this the washer was squeezed into socket...though not evenly :/ (sorry if my tech English is not clear)
My bracket, or "hook", is only one piece and it snaps onto the bolt. I don't think it makes any difference if is is 2 pieces. As long as the derailleur is working once mounted you should be good. The washer on my bolt was already in place too. Try using a small amount of grease on the rubber washer/seal so it seats better into it's socket when you mount it. It sounds like your kit is a little different than this one but should still work.
just ordered the stuff
Hope it helps 👍
Any idea how to remove the X01 b bolt?
From the way this one installed, the b-bolt plate should just pull right off. It’s just snapped in place
thank you!
Hi excellent video. Would you recommend this for GX too? How obvious should the play be to warrant this?
Only if it is affecting shifting. My GX is working fine as is but it is only a couple of months old. Time will tell
@@TonyHob Great video Tony, thanks ! Love reparing my gear. I have a GX (2018) and I will be ordering this same kit. It should do the trick. Will let you know. Ride on !!!
@@doumbugy Hi, Would you like to share how the kit works with your GX derailleur after the upgrade? Have you noticed anything?
Genius.
Nice!!
Did anyone tried this upgrade on 11 speed X1?
EDIT: I went with Eagle AXS cause it was available. Unfortunatly when I clicked bracket, there is little bit empty space. Looks like 11s tube in deralieur is a little bit narrower. I used extra spacer from old set on the last big o ring and it get better. I will check if it works with time...
Check the comments. I think someone said it works
Como hago para compar ese kit gracias
El link está en la descripción
Ese kit de actualización me sirve para sx gracias estaré atento a surespueta
La verdad que no sé
What happened to the larger red O-Ring ? Where does it go or was it not used?
You really should watch the video before asking questions that are clearly in it... 🙄
th-cam.com/video/mcnpBxeb4Nw/w-d-xo.html
@@TonyHob I watched 3x and yeah just caught it and was about to delete my question but you already got to it. Thanks for your prompt reply, much appreciated. Still struggling to get my split ring off my NX... seems almost impossible even with dental picks !
how the fuck do you put that spring washer back on the bolt when you put it back on the derailleur hanger?
