SRAM AXS Setup & Adjustment | Mountain Bike Tech Tuesday 

This is one of the best repair videos I"ve seen (other than the bit about being able to independently adjust for each individual cog, which is not correct) -thanks!

Best explanation of the micro adjust that I’ve seen yet. I’ll definitely be trying to use that to dial in my new GX AXS

One of the best videos showing how to setup AXS. I also reversed the controller buttons from stock.

Important knowledge. This week I was riding and found I couldn't access my 2 lowest climbing gears. Not being TOTALLY ignorant I tried doing a micro adjustment but no improvement. At the end of the ride I found that the chain coming off my pulley was actually touching the cassette teeth when I shifted to the climbing gears. Next day I consulted with my bike tech son-in-law (in house free service!) and learned about the B adjustment. A couple of turns and everything was humming like new. He checked it with that plastic guage gizmo, spot on. The AXS tech is brilliant, though it helps if you actually UNDERSTAND it.

As far as being able to adjust each cog. That was proposed to the SRAM AXS mobile forum a few years ago (SRAM website where you could ask for a new AXS function and people would vote if they wanted it). This particular request got shut down by a SRAM admin with the following answer: "If the derailleur hanger is non-damaged and the frame is designed to industry frame-fit specifications, trim position should not need to be tuned for individual cogs. That work is carefully completed by SRAM engineers as part of the cassette and rear derailleur design process." Kind of a crock of you ask me. I know my gears would benefit greatly if I could adjust each one individually.

in 2024 there is still a note on SRAM AXS website mentioning:"Note: MicroAdjust affects position across all of the cogs. There is no independent adjustment for each cog." so unfortunately, the information in the video is incorrect. I tested this on my eMTB as well and it's imposiible to retain a value in the app per different cogs, each will have the last modified value

Awesome video. Thanks for getting right to it and explaining everything so clearly. Just tuned up my AXS and it’s shifting awesome based on your video.

Unlike other instructional videos on the topic, this one is straight and to the point. :) Luckily I didn't throw away my B-adjustment jig. I have an AXS on my Specialized hardtail and an Eagle Transmission on my new Trek Top Fuel (this week). The Eagle-T has a little wonkiness in the 3rd cog that has it flirting with the 4th cog. So I'll see if I can micro adjust that back into tune.

Awesome tutorial, learnt a lot about the AXS set up. Got my gears running so much smoother now. Very clearly explained. Thanks😊😊

I just learned so many new things about my bike

BEST ADJUST VID out here! First time w axs and you explained it so well. Of course, I stopped when I found a great one. Thanks.

This was very helpful. I unfortunately had to do a deep dive adjustment. But because of your explanation of all set screws I was able to get it pretty damn dialed in. 'thank you

Great video!! Same question about the micro adjustment on each cog, I don't see that anywhere and actually I need it. because the "general" microadjust fix things on smaller cog but it fucks up on the other end, and the other way around..

Love this video. Thank you! Been messing with my AXS and this video was very helpful.

Great vid! one question though, I think SRAM instructs to do the B screw sagged but you dont mention it or seem to do it - in fact I tend to not have much sag when adjusting as I feel the cage doesnt clear the big cogs fast enough if I do the adjust fully sagged?

Switch the auto focus off or the Blur effect on the camera next time it just goes blurry on the derailleur as its focusing on your hand that's closest! Now this update set is cheaper alot more are getting it so be nice to see more of what the derailleurs doing

Thanks for showing newbies how to make adjustments! 👌👌

When I am in my largest cog if I rotate the cranks backwards just a bit the chain will jump several cogs lower in the rear and the derailleur isn't moving. This is important that this does not happen because many times I am trying to clean technical and have to start again by backpedalling a bit which means I am always in the wrong gear requiring me to manually spin the cranks to the granny gear and get back on the bike. Should I try moving the cranks inward to compensate what I think is a chainline issue and is probably considered normal or is there another trick with AXS ? Yeti SB-140 11/52

8:05 new to this. Where is the battery in the shifter and what type is it? I’ve clearly seen the little pack that clips in back by the derailer, but not the shifter.

great explanation, thank you.

finally the info we need ! thanks make more videos related using the app.

❤ thanks guys for helpfull edit. Cheers from Norway!

Why did they remove the micro adjustment from the app?

Dude, such a great tutorial. Thanks 🙏🏽

Lots of hidden nuggets in operating the AXS. Thx for sharing!

Thanks fellas great tutorial.

Should b tension not be adjusted when bike is in sag?

Just saved this vid. Solid info here.

Quick question. I always get a noisier shift going from the 3rd from the largest to the 2nd largest and to the 50t. Derailleur hanger is straighter checked with my park tool. B screw is correct with tool under sag and the chain is the correct length. Any suggestions?

How do you setup the B-tension to account for suspension sag?

Did you set the B tension at SAG or doesn't it matter with the new white tool ?

Will this work for my GT 9 speed? I I’m using a sram 9 speed cassette on my profile hubs.

Is there any micro ajastment method for front derailleur?

Forgot say fantastic video!!

I followed these steps and its shifting a bit better except for when I microadjust to line up large cogs correctly it sends my small cogs nearly a whole cog off and I am just not seeing how to microadjust on the app. When I go to my drivetrain settings for microadjust, there's no arrow buttons for me to actually change microadjust on the app itself. I think microadjusting each cog on bigger and smaller end of cassette individually on the app instead of adjusting the entire derailluer manually doing it with the shifter/controller is needed like you say is possible but I'm unable to achieve this on the app. Any tips on figuring out the app to microadjust differently for different gears/cogs? Thanks!

Could they maybe make a B-tool that doesn’t break?

Thanks for the detailed explanation. I just took delivery of a Canyon Spectral CF 9 with AXS GX. As others have alluded, I cannot micro adjust individual cogs with app v2.0.27. My main problem is that when I put the chain on the largest gear and back pedal, I hear a rasping noise and the chain drops to second gear. What could be wrong? I haven't discussed this issue with the friendly Canyon support yet due to other priorities.

Great Video! New Subscriber, Thanks guys…. 🇺🇸

As always, Great video/tutorial! Ive seen and heard that gx axs works perfectly with shimano 51t cassettes. Have you guys dealt with this combo before?

I have all the gears adjusted perfectly except for the 2nd cog, and it makes the same sound as in 6:47. Is this something you have seen with AXS? It's too bad the app doesn't allow the Microadjust for that one single cog.

Being able to micro adjust every gear is so spicy. Thank you!

Are you sure that micro adjustment is possible on each cog? As far as I know, when it adjusts, it's the same as if it were cable, it messes with all the cogs at the same time, not individually.

Hi 👋 there I watched your video regarding the sram asx setup. I have couple question. I have problem setting up my asx derailleur. I have 2017 Rocky Mountain Element 970 RSL. My Stock group set are XT cassette 11spd 11-46 T, XTR rear derailleur And race face crank. I upgraded now Sram PG-1230 NX Eagle HG 12spd Cassette 11-50T And Sram ASX XX1 upgrade kit. The problem is I won’t stay at 50T cog I goes down.

Just wondering if anyone can advise what the default value is for microshift on the app to start indexing, as the only way to have shift okish from 1-10 is value 28/31, but then it won't shift up from 12-11 unless I go 2 clicks less, which then causes issues at 2. It's a new asx unit along with a new hanger, and b tension set at sag, before anyone asks, never had then issue with my previous Axs unit.

I'm thinking the Rear derailleur hanger causing it. I'm using the stock rear derailleur hanger that comes with the Shimano XTR derailleur. Should I buy SRAM hanger? Or any advice? Thank you

Is it possibe to limit the SRAM AXS to the smallest 9 or 10 cogs only? I’m looking for a solution to my son 20” bike. His hands are small for the mechanical shifter.

When you use the white tool on a full suspension bike, what's the correct way to do it well? Talking about the sag, because once you're on the bike it changes completely

Good of you to mention it, but having the shifters reversed from stock is going to confuse a whole lotta people re: microadjsutment.

Great video. Are you sure you can micro adjust for each gear? Not seeing that feature in the app at all. However, it looks like on road bikes you can. thanks

So I'm shifting but the chain doesn't move up the cassett. I have to push it again and sometimes it then jumps to gears. I guess I need to do some micro adjustments right?

Micro adjust does not work per gear, it is global for all gears… I have spent two hours trying to adjust it perfectly but still lower gears are noisy..

Shouldn't B-Tension be set when the rider is on the bike (under load)?

You forgot to mention that the B-gap adjustment, for a full suspension bike, must be done at sag, per SRAM instructions. Adjusting the gap on a stand is not the correct method. Thanks for the video.

Like numerous others, I have problems accessing either the highest or lowest cog on the cassette. It seems to be one or t'other! The derailleur hanger is not bent, the limit screws are in the correct place and I have the correct spacer on my BB. The App no longer allows you to microadjust individual gears as you ascertained in the video. The screen on the App does exist but does not respond when pressed in any way. In my case the chain catches slightly on the second to smallest cog when I put the chain in my smallest cog. Neither the normal microadjustment, nor resetting the limit screws allows enough movement for the chain to shift completely clear of the second to last cog. The recent Firmware Update has reinstated the microadjustment of individual cogs on the App. However, it would seem that by adjusting one gear, all the other gears are affected. Much in the same way when you do it in the normal way with the controller. One old school hack that people may want to try is to set up their derailleur so that the problem is with the smallest cog. That way if you install a small washer or two between the rear derailleur and the derailleur hanger, the derailleur will be effectively moved out by a millimetre and will sit in the centre of the cog. It sure worked with mine! Thanks for the best video on YT regarding setting things up on AXS... 👏🏽

WRONG. you cannot individually trim each gear independently. Micro adjust effects all gears.

you CANT micro adjust each gear individually . Only on roadbikes

So this messed something entirely. I didn't see anywhere in the video where it says if it will not go into your highest gear. Nowhere in the app does it show to fix that. Limit screw is set to allow it to go down further and it will not shift up that far

The bike is solid and my Ebike conversion went great. ru-vid.comUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Very smooth ride at 30mph with no problems (135 miles ridden so far). The picture is a bit deceiving - there is WAY less space in the center of the frame than it shows. The suspension connection takes up the entire thing. So I needed to attach my battery on the bottom of the frame and my controller on the top. Instructions for assembly were lacking but honestly it wasn't too hard to figure out even though I have very little bike knowledge. Watched some youtube videos on adjusting the disk brakes but that was it. Still, I am loving it and very happy with the purchase.

The bicycle that starts moving in a gear that corresponds to the terrain can be called safe only. This is easy ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qprII2Y-dGA.html

Lol too expensive for my bike...

Don't know which screw is the B tension screw
