Questions and Answers

When can I buy it in South Africa?
From March 26, 2021 selected shops around the country will have it in stock.

How do you pronounce the AXS portion of the groupset name?
AXS is pronounced the same as the word, “access.”

What are the main benefits and key features of GX Eagle AXS?

  • Wireless electronic shifting with engineered hardware for a new ergonomic experience based on touching a button rather than pushing a lever.
  • Faster, more consistent shifts. Letting you shift when you want, under load, without ever having to plan around terrain.
  • Gathering useful data, telling you how many shifts have been made, how frequently each cog is being used, helping you make smarter choices on chainring size, and more.
  • Eagle is a complete drivetrain system that was developed to be an integrated high-performance ecosystem. The engineering and testing that went into the development provide for maximum performance, safety, and long-term durability to ensure a great consumer ride experience. We guarantee this performance when Eagle drivetrains are used as a complete ecosystem.

ccs-62657-0-89184900-1616509370.jpg

What is included in the GX Eagle AXS upgrade kit?
Derailleur, Controller, MatchMaker, Charger/cord, SRAM Battery, Battery cover, and a Chain gap tool.

When is SRAM GX Eagle AXS available for retail aftermarket purchase?
We will begin providing product to the market on March 26, 2021.

Are there different colour variants available?
GX Eagle AXS will be available in GX’s lunar colourway.

Can I fit SRAM GX Eagle AXS to any mountain bike and what are the compatibility requirements for GX Eagle AXS?
All current bikes and frames compatible with Eagle today will be compatible with GX Eagle AXS. GX Eagle AXS requires an XD driver body for cassette installation, just like the majority of our current 1x drivetrains. GX Eagle AXS cranksets use SRAM DUB bottom brackets, compatible with almost all current BB standards.

How does SRAM GX Eagle AXS connect and integrate with other wireless components that SRAM makes?
All AXS components can connect to one another using our proprietary encrypted wireless network. The AXS mobile app is used for personalization of the component controls and to serve as a single access point for all SRAM AXS connected products. Additional connectivity included with AXS is ANT+ and Bluetooth.

Does SRAM GX Eagle AXS have smartphone connectivity?
AXS components have Bluetooth connectivity through the SRAM AXS app. If there is a firmware update, it can be handled through the app. There is no dongle.

ccs-62657-0-04213000-1616509956.jpg

What prevents an AXS groupset on one bike from wirelessly interacting or interfering with an AXS groupset on another bike?
SRAM AXS uses a fully encrypted, secure and proprietary SRAM wireless protocol that has been proven in the real world in our road drivetrain applications and more recently on the World Cup circuit.

Is SRAM AXS waterproof?
The GX Eagle AXS system is completely water and dust proof to the IP69K international standard. Initially developed for construction vehicles and food sanitization, the IP69K standard validates systems that require regular pressurized cleaning. For a mountain biker, it means no hesitation to head out when the weather looks less than ideal. When washing AXS components be sure to avoid high pressure washing, like other components on a bicycle there are many moving parts with lubrications that can be washed away with aggressive washing techniques.

Are RED eTap AXS shift levers compatible with GX Eagle AXS rear derailleurs?
Yes. All AXS components can connect to one another. You can use SRAM RED eTap AXS shift levers to build a drop bar bike with an GX Eagle AXS drivetrain. The GX Eagle AXS drivetrain is also compatible with the road BlipBox and control buttons.

What chainring size options do you offer with SRAM GX Eagle AXS Groupsets?
Aftermarket complete group sets will come equipped with a 32T chainring on GX Eagle AXS. Aftermarket Eagle chainrings will be available in 30T, 32T, 34T, 36T, 38T.

What cassette size ranges do you offer for GX Eagle AXS?
SRAM GX Eagle AXS uses the X-DOME Eagle cassette with a 10-50T or 10-52T.

Is there a cassette available with an 11-tooth start so I don’t have to change the driver on my rear wheel to XD?
SRAM offers a PG-1230 Eagle cassette which utilizes the HG splined driver body interface. This is compatible with all of our Eagle drivetrain parts as part of the Eagle ecosystem. However, for optimum performance the XG-1275 cassette is used in the GX Eagle AXS offering.

Will a new RED AXS road chain work on a SRAM Eagle drivetrain?
No. SRAM EAGLE chains and SRAM RED AXS chains have different dimensions and are not cross compatible. The derailleur, Cassette and chain should always “match”. When using an Eagle cassette or derailleur, use a matching Eagle chain. When using a SRAM RED cassette and derailleur, use a RED chain.

Are SRAM GX Eagle AXS PowerLocks different from SRAM RED eTap AXS 12-speed PowerLocks?
Yes they are. Eagle PowerLocks can be easily differentiated by the word “Eagle” stamped on the side.

What is the max cog size that is compatible with GX Eagle AXS rear derailleurs?
52T. GX Eagle AXS derailleurs are designed to be used with both Eagle 10-50T and 10-52T cassettes.

What is the Overload Clutch?
The GX Eagle AXS derailleur is smart enough to protect itself thanks to its incredibly resilient Overload Clutch. In the event of an impact, the motor gearbox disengages, giving the derailleur freedom to move, and instantly returns back to its position for a seamless experience for the rider. The primary purpose of the Overload Clutch is to protect the derailleur shift motor, but it serves to protect your derailleur and derailleur hanger from damage as a by-product. A very helpful by-product.

How robust is the GX Eagle AXS derailleur?
Several design features increase the robustness of the GX Eagle AXS derailleur. The gearbox and motor clutch, the shorter cage, more chain wrap, and more precise shift control all add to a more durable system. We also have extreme water and dust proof qualities built into all our AXS components.

Are 11-speed RED eTap derailleur batteries compatible with GX Eagle AXS and SRAM RED eTap AXS derailleurs?
Yes. Both groups use the same SRAM batteries.

Only done approx 100km so far. Tested on all sorts of terrain.

 

Flawless and crisp!! Couldn't be happier....

Mine arrived today .....

 

Any tips for a novice bike mechanic?

 

 

Spent the whole of Easter sunday installing  :wacko:

 

The physical installation wasn't so bad actually but when it came to the set-up and adjustment I really struggled.

 

 

The main issue was the middle jockey wheel clashing with the 2nd biggest cog on the cassette.(I fitted a new chain which I lengthened by 2 links to accommodate a previously fitted bigger chainring.

 

Couldn't seem to avoid the clash despite wearing YouTube out!!!

 

Eventually opted to refit the original shorter chain which worked but left me with indexing problems only to discover that I needed to re-adjust the B screw.

 

After that and some minor indexing she worked and I had to set about placating Mommy.

 

Did an 80km ride to Northern Farms with our mtb group and the AXS performed like a steam train - not a beat missed - just have some minor cockpit adjustments to be made and I set to enjoy.

 

PS

I also installed the new Rocker paddle. Highly recommended!!

did you do it at 30% sag ?

 

how did you do the B-limit screw ? you did the 3mm gap or used the provided tool ?

I didn't do it at the 30% sag - good point though it seems to be working well (must the B screw be set while at 30%?)

 

I used the provided tool.

Let the pressure out the rear shock so its sagging....

I so don't need this...But oh sooooo badly want to do the upgrade

 

My current mechanical GX ain't bad bad although I was considering transitioning to the M8100 XT setup for shift crispness however, this seems to be a total game changer...Damn you SRAM for tempting us with this!

Jbr

Apr 6, 2021, 5:22 PM

I first rode it without doing the sag and doing the 3mm visually (more like 5mm) and it worked fine, did it again with the sag (took most of the pressure out the shock but still had to apply pressure to keep the shock at 30% sag) it works just as good ;) can’t say it works better or worse but when in doubt, just follow the manual ????

Sorry to tell you this... but it is game changer. I loved my force axs on the road bike from the start so I was expecting to like it but I’m really impressed on how much it makes a difference, now I just want to ride my mtb every day...

Such a pretty sound.

 

Now I am considering getting one for my Shimano XTR machine - just not entirely sure if it will definitely be compatible???

Everything I have found is that it is compatible whether you use the mechanical group or AXS.

Thanks Mate,

 

There was some discussion about using the correct chain, which is the only part that comes into contact with the AXS other than the bolted connection (I think)

your chain is more in contact with your cassette (generating traction) than with your derailer (pulley wheels juste guiding your chain). I would stick to the XTR chain as long as you're on the shimano cassette, and then the day you go for a sram cassette get the XX1 chain.

 

BTW today I added a little more gap than the recommended 3mm at 30% sag on my shimano/AXS setup, shifting is smoother. I must be at around 4/4.5mm gap between the pulley wheel and the closest tooth on the biggest cog when the chain is on the 2ond biggest cog. Best setup I've had so far. I found it was a bit rough changing to harder gears with the 3mm gap

Are you not lining up with the pulley axle centre as per the supplied tool?

The supplied tool doesn't fit on my XT cassette when the chain is on the 2nd largest cog

 

Not sure how it's supposed to fit between the cog and the chain on a sram system if the gap is the same between the two cogs...

 remember the SRAM cassettes are made of steel; so the thickness of the sprocket will be thinner than the alloy sprockets on the XTR cassette. There's also ramps and pins on the XTR cassette that will make the space between the sprockets smaller.

The distance between the centre of the top of the teeth from sprocket to sprocket is very similar across the Shimano and Sram products even though the gap isn't the same. That centre to centre gap is what makes it possible to use Shimano derailleurs and shifters with Sram cassettes and vice versa

Thanks for that DD

 

You’ve inspired me to order another one for my XTR shod bike. (Even got a better deal)

 

Hope to have it in hand and installed before our trip to Clarens next weekend. ????????????

I ordered a second one for my Stumpy and installed it at 23:30 for a ride the next morning hahaha... the AXS units work so well. I barely had to do anything (I replaced a normal GX Eagle derailleur).

Did the GX AXS upgrade last week.

Impressed beyond measure.

Survived Cape Munga Grit...40 hours of torture.

No issues with the shifting, and the battery is still good.
