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:

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.

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.

In love, never looking back!

Familiarity:
I've used it several times

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.

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.

Amazing

I was lucky enough to grab it when it was in stock. I don?t regret getting rid of the old cable actuated derailleur. Electronic shifting is the future. Very crisp and accurate shifting. Im still on my first charge of battery going 6 hours Of riding. Very easy set up and I?m glad I upgraded.

Install was ridiculously easy. Shifting is magical... Never miss a shift and barely lift a finger to trigger it. I put a lot of miles on my bikes and group sets and switching to SRAM's electronic group sets was the best investment in my riding that I could make. Love the compatibility, value, precise effortless shifting and would recommend this to every rider out there... #SRAM#AXS#mullettbuild

Pretty Rad

I seriously considered buying AXS a few times but couldn't stomach the price. When the GX came out I was sold. I was amazed how quickly it shipped given it was supposed too be backordered. But I had it in a week. Performs flawlessly and I have yet to dump the battery mod ride. I've had a couple of crashes since installation and no bends or breaks. No malfunctions to speak of. Pretty uses to the paddle shifter now and pleased with it.
