Why We Like The GX Eagle AXS Upgrade Kit
Masters of trickle-down technology, SRAM has impressed us again with the GX Eagle AXS Upgrade Kit. We’re installing this on our bikes right away, ditching the cables and housing that clunk around in our frames all day. Long-awaited, GX AXS Eagle opens the door for a lot more than just dentists to have electronic shifting. GX AXS uses the same proprietary wireless tech as other AXS items, so just like mechanical AXS we'll be able to mix and match the full system.
Ahead of the game, the new GX wireless shifting from SRAM enjoys all the years of testing that X01 and XX1 went through. We’re especially enjoying the crisp feel of the electronic drivetrain, and that every shift feels the same when the element of human error is taken out of the equation. Easy to adjust, the upgrade kit hooks up to the SRAM AXS app instead of having to drag out the toolbox.

Great value
- Familiarity:
- I've put it through the wringer
The GX AXS upgrade kit is the best value for getting into wireless shifting. The weight difference is minimal compared to the highest tier with no performance difference. I was skeptical about wireless at first. It is the most smooth, quiet, and fast shifting I’ve ever had. It is a little expensive, but worth it.

So far so good

- I've used it once or twice and have initial impressions
Bought this since it was on sale. Install went super smooth and everything seems to be working perfectly. Haven't had a chance to try it on the trail since it is winter and everything is still too muddy to ride but so far so good.

Awesome shifting upgrade, bad ergonomics
- Familiarity:
- I've used it several times
This upgrade is totally a game-changer … except for the paddle. SRAM obviously didn’t test this with many riders because everyone I know that has upgraded to AXS has had to buy the redesigned paddle upgrade. They should have included that from the beginning or offered a free upgrade. That’s probably why all new bikes with this system come with the new paddle automatically.

Robo-shifting
- Familiarity:
- I've put it through the wringer
Admittedly I am no expert on electronic shifting, this is my first electronic drivetrain. That said, the shifting with AXS is unbelievably smooth. Not only is it quick but you can shift under power (don't recommend doing this anything with any drivetrain) without the worry of a delayed or clunky shift. If you are looking to upgrade your existing Eagle drivetrain consider this upgrade kit. It'll transform your existing drivetrain. Plus your bike will look better with less cables and the robo-shifting sounds awesome.

Only 55 grams heavier than mechanical GX
- Familiarity:
- I've used it once or twice and have initial impressions
I replaced my worn mechanical SRAM GX rear derailleur, cable and shifter with this kit. Install was confusing initially but, in the end, easy. I weighed the parts I took off my bike (shifter, cable, tubing, and derailleur), which together totaled 480grams. So this e-shifting setup is only 55g heavier (~1/8th of a pound). So far, so good!

In love, never looking back!

I am absolutely in love with this setup. The shifting is instant, silent, and super crisp. I always hated my mechanical setup, always having to adjust the cable tension and I could never quite get it right. I felt like me previous setup was always missing shifts. Setup was insanely easy. I followed the instructions, set my limits, did a couple micro adjustments, and it's amazing. Took maybe 30 minutes to install. I'm no drivetrain expert, but I found the setup to be pretty smooth with basic mechanic skills. Very plug and play. It does take a little getting use to the new shifter. I do really like it, it's just a little different ergonomically. Not in a bad way, just a totally different feeling. Took a little tweaking to get right, but now I find myself loving it. I typically just rest my thumb on it comfortably while I ride. It comes with a really nice little multi-tool, I took that along on my first ride and spent a little time adjusting the shifter location. Super easy. The battery is great...rarely have to charge it. I may end up buying a spare just to keep in the car or gear bag, but I don't feel it's really necessary. Might just be nice to have a backup. If you're on the fence, I highly recommend it. If you're tired of your mechanical setup like I was, you'll be stoked on the upgrade.

mixed emotions! :(

the shifting is instantaneous, crisp and smooth on jeep roads. not so much if you shift under load ( alot slower than shifting with the wired gears when under load) had it since Christmas '21 but the problems for me are the ergonomics. just cant get it to feel comfortable in my thumb. i had it attached to the break lever and it was horrible. used the stand alone clamp and got a little better but still not for a long ride. ordered the paddle kit to see if it gets better my recommendation would be TRY IT BEFORE YO BUY IT.

Great product until it fails
My son bought the AXS and loved everything about it for the FIRST YEAR. In fact, he would have given it similar reviews found on this page. Then, at an enduro at Silver Mountain in Kellog, ID it started to lose connectivity between the shifter and the derailleur. We discovered that the plastic on the battery had worn down so the fit was no longer tight enough to keep connectivity. He was lucky enough to borrow a battery from a fellow rider and finish the enduro. A week later, after purchasing a new battery, he unfortunately snapped his chain during a ride. After purchasing a new chain, we found that the derailleur no longer worked. We took it to our local mechanic who said it was broken and needed to be serviced, but when I called SRAM they said that the AXS is not serviceable. When I told the customer service rep that my kid was really bummed to have worked to pay off the AXS upgrade and then just a little over a year later have to purchase a mechanical derailleur and shifter for another $300, he simply retorted, "biking isn't cheap." I agree it's not cheap. However, maybe SRAM and other developers should consider that when a new product is 3 to 4 times more expensive than the mechanical derailleur, they should build a product with serviceable/replaceable parts. So, be aware that when or if something goes wrong with this system, you just have to buy another one. IF YOU RIDE A LOT, think about the cost of replacing this derailleur every year or two compared to the cost of a mechanical derailleur. We will not buyer another AXS at this price point.

What all comes with this kit?
March 25, 2021
My current Mtb has a new Sram AXS Reverb dropper seat post which I purchased from you and I LOVE it! My question is: Will the Sram GX Eagle AXS upgrade kit work on my SRAM XG 10-42, 11 speed XD compatible only cassette? Thanks, and keep up the great work and customer service!
