X01 Eagle AXS Upgrade Kit

If your bike is already equipped with a SRAM Eagle drivetrain, the X01 Eagle AXS Upgrade Kit allows you to make the switch to wireless electronic shifting without needing to buy the entire AXS groupset. The kit includes the XO1 Eagle AXS derailleur with battery, the Eagle AXS shifter (SRAM calls it the Controller), and a battery charger with charging cable. These components are all you need to make the switch, which means you can continue using your existing Eagle cranks, cassette, and chain to save yourself a bit of extra cash on the upgrade.

If you're reading this then you're probably debating why you should make the switch to electronic shifting. Doesn't that make my bike more complex and harder to maintain? The truth is, it's actually the opposite. AXS shifting removes the hassle of routing cables and housing through the frame, and you'll never have to worry about cable stretch or wear. This means crisp, responsive, consistent shifting that rarely needs any adjustments. You'll also enjoy a cleaner cockpit thanks to one less cable, and you can customize the buttons on the shifter to do exactly what you want. Setup is as simple as mounting the derailleur and setting limit screws, installing the shifter, and then powering on the system and pairing the two.

If you're concerned about the durability of the Eagle XO1 AXS system, don't be. Compared to mechanical Eagle groupsets, the Eagle AXS derailleur has been contoured around the frame design a bit more. This translates to increased chain wrap, which improves both load distribution and durability, reducing wear and tear on your chain and cassette for better longevity of components. Dually, this new positioning offers a whole 10-millimeters of increased clearance over mechanical Eagle rear derailleurs, meaning your less likely to bash it on a rock or encroaching root. If you do smack your derailleur against something, there's a special Overload clutch that disengages the motor in the event of an impact, allowing the derailleur to move whichever direction it needs to in order to protect the internal motor. As soon as the impact is over, the derailleur automatically reengages and shifts back to where you were, without skipping a beat. This built in protection gives you some serious peace of mind when you’re dropping big dollars on a groupset.

An ever-critical question with mechanical groupsets is battery life. All day epics packed with steep climbs and rowdy descents mean a whole lot of shifting, and can be trying on a battery, but SRAM is confident that the derailleur can run for 25+ hours from a single charge. The battery is removable, so you don’t have to bring your steed into your living room to plug it in, you can simply pop the battery off of the back, and bring it in to be charged easily with a USB device. SRAM’s AXS battery remains the same from its derailleur to RockShox Reverb AXS dropper post, so if you’re sporting both on your bike you can swap the batteries around, should one run out of juice before the other. In the front, the shifter runs off of a single watch battery, and claims to have over a year of life from a single battery, keeping maintenance low.

When things get wet we can get weary of electronics, but the Eagle AXS groupset is built with seals designed to keep things working flawlessly, whether you’re booking it across a lofty stream of snow melt, or get caught in torrential downpour at the summit. With that said, much like any other components, we don’t recommend hitting it with a jet stream to wash it, as you may be able to damage the seals.

With the small price difference between SRAM’s XX1 and XO1 Eagle AXS Upgrade Kits, you’re likely wondering what the difference may be. While on SRAM’s mechanical groupset line you found a slight difference in performance between the two, and a major weight difference, on the AXS side of things you’ll find that the two derailleurs perform equally. The difference you will find is in weight. SRAM’s X01 Eagle AXS group is built to be much more robust, holding up to more demanding terrain and trying conditions, and as such it’s got a few extra grams above the XX1 model, which is designed to dominate the cross country race scene. Despite the addition of batteries, both the X01 and XX1 AXS groupsets weigh less the traditional mechanical Eagle groupsets.

Works!!

  • Familiarity: I've used it several times

That's all that really needs to be said. This is my third bike with electronic drivetrain components( 1 Etap Red, and 1 Di2) and it works just as flawlessly as those two! I was concerned with the ability to quickly dump gears when caught in too high a gear coming out of a creek bed or unexpected climb but this thing shifts just as quickly as you can hit the button. Additionally, being able to fine tune the alignment and not having to worry about cable issues is one of the best and most overlooked advantages of electronic systems.

lives up to the hype

just a warning on the picture, at the time I am posting these we are showing with crank, cassette, and chain, it does not include those.
This kit includes - shifter, derailleur, 1 battery, and charger.
I'll give more of a review later but wanted to make that clear. A couple rides on it and totally worth it, was actually not expecting it to be as good. Shifting is fast, precise, exact. It was easy to set up, even I could do it easily by watching their video on youtube. contact me with any questions you have on it.

Had a chance to install and ride so here are my initial impressions. I hate that I really love it, yea really. I didn't want to love electronic shifting on a mtb, I mean come on, it's a mtb. but it was easy to install, and easy to tune, and I'm no master mechanic. I've ridden hard and even raced for a few weeks now and it's been fantastic. fast, crisp shifting. it did take a little getting used to the different feel to shift but after a ride your brain gets it down. It is expensive, agreed, but if you are spending as much on your mtb as you do on your car whats a little extra to get the best.
