**This is probably the best (clear and to the point) description of fine tuning a Sram 12-speed derailleur on youtube. No detail left out. Items covered that most videos fail to mention: --Pre-barrel adjustment position. --Removing cable prior to adjusting high limit screw. --Setting bike to sag prior to using SRAM B-gap alignment tool. Excellent videography angles and great description. Thanks so much. Now all I'd like to see is how to determine chain length on a new chain. :)
Something else worth noting is that the teeth on the largest gear of the cassette vary slightly in length and shape. When setting the B-gap its best to use the longest slimmest tooth on the cassette as the one you check against the line on the tool. When you have the tip of the correct tooth against the line all the other teeth match up in size and shape to the unfrosted portion of the tool perfectly. Also one other thing Ive found is that setting the tip of that tooth to the very top edge of the line (like barely touching it) provides best shift performance in most conditions. Great vid by the way. Cheers.
Thanks for putting this together. These are the clearest explanations and far and away the best visual perspective of exactly what is happening and why. Fantastic.
My brand new bike I got last year was shifting like an F1 car up until I had a bad crash about a month ago. Ever since then I have not been able to dial the derailleur back in. I got a new hanger which didn't help, I was about to buy a new freaking derailleur until I watched your vid. I do not have a chain gap tool but I set my distance between the cogs to 15mm (what other sources online said works well). Anyway doing that and then fine tuning by threading the barrel did the trick. She shifts like a race car again. The SRAM manual is horrible at explaining this. Before I watched this video I was sad, but after watching it I am happy. Thank you for making my life better.
Many thanks, best tutorial I came across. It would be helpful to understand how to deal with derailleur which are damaged, when to figure our if a new one is needed.
Thank you so much for this video, it really saved my day. I've watched several other videos about the basic setup of the sram gear changer, but with all the other videos I wasn't able to do a flawless setup. Since I set up my sram like shown in your video it works just perfect. Thank you so much for this.
Followed this guide today on mine- did the trick. 2 slight changes for me: a)I got a helper to sit on the bike while I was adjusting the B screw b)I didn't have the SRAM guide tool, so had to do it by eye Shifting beautifully now- many thanks.
Great vid. One thing I was struggling with and didn’t see explained on other vids was adjusting the gap at sag level. Spent a lot of time trying to get gears running properly, once I understood this, worked first time. Thanks
Thanks, just what I needed to get my Eagle setup from good to perfect. Also thanks for the English narration, my only other language is very limited Spanish so I appreciate you taking the trouble to speak what is I'm fairly sure not your first language.
Good video thanks, I’m installing the NX version over the next few days- it was interesting to see you didn’t Line it up exactly on the high gear. I bet you were delighted when your friend smashed your $250 mech,
Excellent video. I recently stripped and cleaned my GX Eagle cassette, chain and mech and the shifting was terrible when ir einstalled them. After watching this a few times the shifting is now perfect, and much better than before!
@11:01 min - chain is not synced with cassette teeth in the largest cog. You can see the chain riding up on the cassette. The biggest pain in the ass with Sram eagle shifting.
Greg Knipe lucky you. That is not the case with me. Eagle is a great product until you start abusing it/riding fast. I’m guessing the long derailleur cage is super sensitive to vertical alignment. Never had many problems with 11 speed but I have been plagued with issues from racing enduro and bike park days.
Great video. Could you also add how to adjust the B-Gap without the proper tool ? It's not so easy to find,. Having the B-Gap adjusted properly with the red tool, maybe with a caliper or a ruler, you could point exactly where and how much measure. Thanks
Fantastic! Great explanation of the different important steps. This is my go-to quick reference guide whenever I have issues with the finetuning of my Eagle drivetrain.
Perfect timing, just had some trouble on a ride this weekend and needed these tips to get me straight. Thanks for the information. Ill get connected to your forum as well. I appreciate your channel.
Thanks for the super helpful video! I have a question: when I am in the 50tooth sprocket, if I backpedal more than a few turns my chain drops down a few gears to the middle of the cassette. I tried playing a little with the B-tension screw but still getting the dropped chain. Its very frustrating when trying to ratchet my way up a technical climb or if I'm rolling backwards a little on an incline Is there a way to set up the derailleur so it doesn't do this or is that just a fact of life with the SRAM eagle (I have NX) derailleurs?
There are a hundred other rear derailleur adjustment videos on RUclips. Yours is the only one that starts the adjustment process on the low gear. All others start at the high (smallest) gear.
Thank you very much, this was extremely helpful. Even though I will be having the NX drivetrain installed, possibly with some GX components, this information is applicable across the whole SRAM Eagle line, as far as I'm able to discern.
Did you notice that at 11:02 in your vid where you are doing multiple gear shifts that at the top 50T cog your chain is out of sync with the sprocket? You then upshift and immediately down shift back to the 50T and it is then in sync? Any thoughts on why that is happening or just life with Eagle?
hi. 2 questions: 1) shouldn't you be compensating for sag? 2) do you experience any chain rub when on the 42t sprocket? i find that the 42t and the 50t cogs seem very close together and when sitting on the 42t one, the chain touches the inside of the plate
Great video. Do you have one showing how to get the chain length right? I added a Wolf Tooth 44 GCX to replace the 42 on my X01 1x11, and replaced the chain with a new chain two links longer, thinking two more teeth should mean two more links, but it seems too long.
I got the NX Eagle without a crank. I took a good mechanic in town for the installation, but noticed that the chain was visually too long, the COG 50 didn't "stretch at all" - but the detail is that her tension was perfect! and the feedback is also OK. So in cleaning, I decided to check, and she was 8 links after the junction, making the standard measurement of COG 50 and crown .... I removed the 4 links ... Out of curiosity, I went to see the feedback and to my surprise, I was very far from the COG and had to realign ... loosing screw B ... (flustering) Until then, ok, but I noticed that the chain seemed less intended and to my surprise, get off the pedal and it seems that it is "beating" much more! more loose! My logic is that with the long chain, bolt (screw) B needs to be tightened, pulling the gear and letting the chain much tighter! But and now? return the 4 links and intend or use as directed? (google translator, I´m From Brazil)
at 11:02 it is clear that there is nothing right with the chain with the 50t pinion, the same thing happens to me sometimes, do you know that it is due?
Wow...gonna have to try this on my XX1 setup today. Totally new to bikes as I come from motorcycle background. I can build engines without problems, but this is like black magic to me. :D
It's easy ;) For sharing your cycling moments join our group facebook.com/groups/sickbiker/requests/ For getting help and halping other join our forum.sickbiker.com/ :)
I watched a Sram video and they said your supposed to use the red gap tool while sitting on your bike in the recommended sag % for your rear suspension and then have a friend set the gap while suspension is compressed into the proper sag, have you seen this ?
If i size chain length the manual says it also looks like your setting. From the factory my chain was one outer en one inner link too short as what the manual says
He said it was a new one :) I put degreaser in mine (carefully on each barrel, not just spraying it), let it soak for a minute, and brush each side with a nylon brush. Rince it with water to clean the maximum, then with paper towel each side until it's perfect. Then I dry water that is left with a blower. Grease it with a droplet on each barrel, turn the chain for 30 sec, let the grease sink in barrel joints for an hour, and one full rotation with a paper towel to catch grease excess. It sounds like a log of work but it doesn't take more than 10 min. The chain always looks brand new, if you're doing it regularly it easier than if you wait too much. The trick is to wipe off grease excess (only barrels need to be lubricated) so it doesn't catch too much dust.
For some reason there are two different versions of the b-screw adjustment gauge. I have the other kind, and it works a little differently but the basic technique is the same of course
The concept is that because of the wide differences between cog sizes on the climbing end of the cassette, the gap between the jockey pulley and the cog needs to be greater for for the chain to hit the ramps on the next larger cog. Before SRAM was issuing the tools, I used to adjust the B-screw with the chain on the second cog, loosening it just enough for the chain to make the jump to the first.
Great tutorial. My question is why does the chain jump off the low gear when peddling backwards? Functionally shouldn't matter but it just doesn't seem right that it does. Thx again,
What the hell, mine doesnt shift up or down any good, I can adjust the derailleur a lot either way and get is to work shifting 1 way ok but then the going the other way is completely off :( any help?? chain length is good and b screw is fine
Hi, Thanks so much for your video tutorial. It worked great on the derailleur kept jumping out or hard to shift to smallest cog. I also have 1 question for and hope you can help. While biking and quicky biking uphill, from small cog (4/11) to (7/11) large cog. I got problem with chain skipped gears and make loud noises while hard pedalling. I'm wondering if you have any suggestions with that please? (New bike 2 months old). Thanks.
Actually, I would do BOTH limit screws before putting chain or cable on. Manually push the derailuer to the low gears and hold in place while adjusting the limit screw. Thats how the Barnett institute teaches the process.
@@samh8525 in order to do both... keep the shock at my sag level and adjusting the B-screw... do I need to get a second person to help me, then? I was wondering if any of you knew how to make this a one-person job?
At 10:09, I see that the chain did not sit correctly on the 50 sprocket for 1second. The chain rides on TOP of the sprocket teeth instead of meshing with them. It is a common problem of the Eagle "technology".
I've been using Eagle 12 speed for near 3 years and I have seen the same thing occur on my bike when tuning on the rack - but it has NEVER acted up or created a problem when on trail and under riding conditions - and I live where the granny gear ratio's are used pretty often (and I'm an older guy- lol)
@@sherwoodispower i had same issue this past weekend with new chain and very lightly used cassette in the stand...i spent 30 min trying to get it right.......but it worked flawless when doing test ride in the 42 and 50 with high torque climbing in the back yard testing
Had the same problem with eagle. Almost nobody knows this, but 2 biggest sprockets on the cassete are actually narrow-wide. Chain in the video is missalligned by one tooth.
Thank you for the video very useful any advice for a LT woo Ax group I did buy it from AliExpress I am in the process of installing on mi bike a marlin 7 2019 I am doing an up grade from 3-9 to 1-12 thank you

I think this video should be renamed have to adjust the Eagle drivetrain!
It's 4 years old video and it's still the best explanation
Very easy to understand and very useful

this is by far the best clearest easiest to understand tutorial I have seen on SRAM derailleur adjustments..and I've seen a bunch! thank you... 👍👍👍
I adjusted my derailleur according to your method and it worked better than it was when it was brand new!
Great video!
Thank you!
Excellent step by step for this, a lot of guys afraid to mess with the hi-low screws or go way too much without watching lower cage movement.
This gentleman's guide should be on official SRAM's youtube channel!
Wow even for 5 years old this is great content. Better than SRAMS video in my opinion. I’ve recently learned how to do all this. Great skill to know
Best tutorial I saw till now. It explains a lot of possible flaws, other tutorials don't deal with. Great.
I want to thank you !! By far the best adjustments and great explanation and camera views . Finally got my setup smooth flowing! 🔥
Ive adjusted my Eagle drivetrain multiple times with this video. Best video out there for this topic... easy to follow and actually works :) thanks
Best video I've seen on how to adjust Sram 12 speed
Thanks man, as a lifetime user of shimano and now switching to sram MTB groupsets, this is really helpful
Great video Daniel. I couldn't get the shifting on my xx1 perfect like in your videos. I hope now I will.
The best vids like this one always include the common mistakes made, very helpful.
Finally somebody who explained exactly what I was looking for!!! Thanks a lot

You are awesome 👏, even the the SRAM channel didn’t go through the adjustments in as much detail as you did :)
Best video for adjustment on the web.... Thank you so much, PLEASE keep posting bike maintenance tips.
Ryan Alexander agreed 👍
Thank you so much. I hope this helps me get my new chain/cassette actually working properly. Not thrilled about the issues I have been havinh

I did the same mistake. But corrected it by listening to the chain noise that reduced only when i did fine tuning. So the noise tells you the story
Great vid man - that chain riding up on the 50T looks a little quirky though.
Why shall we not align the two centers?
Thanks, just what I needed to get my Eagle setup from good to perfect. Also thanks for the English narration, my only other language is very limited Spanish so I appreciate you taking the trouble to speak what is I'm fairly sure not your first language.

Awesome - was about to book my bike in for a gear tune up, but followed this video and now as good as new!! Thanks for sharing mate👍👍
At 8:35 the B-screw adjustment is complete and shown with the plastic template gage from SRAM. This same dimension can be set with a caliper to 14mm for 1x7, 1x11, 1x12 speed (1x= single front chain ring) for example a X1 or GX derailleur will work too, not only Eagle with the same red-colored template or 14mm. See SRAM online, downloadable manual: 95-7518-008-100 Rev A © 2019 SRAM,, pages 21 -25

Fantastic! Great explanation of the different important steps. This is my go-to quick reference guide whenever I have issues with the finetuning of my Eagle drivetrain.
BEST Video so far for setting the drivetrain!!! Thanks!!!!
Yup, that's the key, you got to release cable before high limit screw. Nice job, good video!
Excellent vid. Thank you. Your clear presentation is one of the best I’ve seen.
Very clear and detailed instruction ALL details shown clearly and NO stupid music best i have ever seen
No entiendo ni hablo ingles,y aun asi el video es excelente! se entiende muy bien y es muy intuitivo! Gracias y seguid asi!

I wish i had found this video sooner thanks!
Great video - love the colour of your chain and cassette. Thanks for sharing.
Thank you so much. I have just adjusted my drivetrain. I have the Sramm NX 11 and the video worked perfect for me.

Hello. Did You find a way what's happened? I have the same problem
At 10:09 it does the same thing. Mine does the same, and i lost some time with this problem, but now i see it here....so it's a design flaw.

Jose Collazo that happened to me when I took off the chain, I just changed direction and it stopped.
The best video of adjustment I've ever seen !!
Just what I was looking for, I made the same mistakes! I feel like the sram b-gap tool can be printed out on a basic printer?
Thank you so much, best video out here to get this system adjusted!
lol , i was adjusting towards the bigger cogs .. THANX MATE. you saved my day
Thanks , best vid ive watched today for setting up my new sram nx groupset ,never quite sound as smooth as yours but job done, much appreciated ! 👍🙂
Can you do a video on how to set chain length on a full suspension bike ?
Perfect, thanks! My NX Eagle upgrade is dialed in now.
Thank you. Amazing video, very logical adjustments, very smooth!

maybe the crown u use is not the right for your chainline, 3mm offset for boost 6mm for normal i think.
en el minuto 11:02 se ve claramente que no engrana bien la cadena con el piñon 50t, me sucede lo mismo a veces, sabes que se deba?
Jose Collazo a mi me paso lo mismo cuando quite la cadena para limpiar, sólo cambie la dirección y Santo remedio.

What a great video. Very easy to follow and clear instructions too. Thanks for posting.
Very helpful video but how do you keep the bike in the sag position when setting the B gap ?
Strap it together. Can use gorilla tape if you don't have straps.
Hi,
Thanks so much for your video tutorial. It worked great on the derailleur kept jumping out or hard to shift to smallest cog.
I also have 1 question for and hope you can help.

Adjust your B screw.
Much easier to adjust the b-gap with the tool if you have someone to help you, you can just sit on the bike and have the other person adjust the gap.

Actually, I would do BOTH limit screws before putting chain or cable on. Manually push the derailuer to the low gears and hold in place while adjusting the limit screw. Thats how the Barnett institute teaches the process.
If I am just changing the rear derailleur and using the existing chain, I do not need to adjust chain length, correct?
As long as the gearing stays the same you should be good
really well done. hits all the points.
How do you compress your rear shock in order to adjust the B-screw? Does the shock need to be compressed while doing so?
Alejandro Gomez - same thing I’m wondering.
Let the air out of the shock and position the bike at your sag level...
@@samh8525 in order to do both... keep the shock at my sag level and adjusting the B-screw... do I need to get a second person to help me, then? I was wondering if any of you knew how to make this a one-person job?
