SRAM XX1 Eagle AXS Rear Derailleur Rider Review


Let me begin by saying that I am a sucker for new technology. I am not a tried and true type of guy when it comes to bikes and bike parts. I like the cutting edge ideas and equipment. But I am an average guy with maybe above average bike skills. However, if the design or part doesn't work, I will get rid of it immediately.

This is the second Eagle AXS derailleur I have purchased. The other is living on my gravel bike. Why? Because I think they are excellent and I wanted consistency in shifting between the two bikes.

Background - I ride east coast singletrack. It's full of quick ups and downs, roots, rock gardens which require a ton of shifting, application of power, and quick moves. It's hell on drivetrains. If they don't shift well or consistency, my trails will expose the weaknesses.

Shifting - This is the job of the AXS system period. It works really really well. Why? Not black magic. Just precise engineering. Time and time again. I have been asked:

"How does it shift?" My answer is, "It's great because I  haven't been paying attention to it. Maybe that's the beauty; when it works right, it's invisible.

Adjustment - The AXS system makes it easy to adjust. No more or less than a mechanical system. Get it set right and leave it. No cable stretch. No changes. Oh, and if you bash it, it returns to where it started. I have tested that. The micro-adjust acts just like a barrel adjustment. But I think it's better and easier. It's been the most stable setup yet.

Software - Easy to set up too. But can be finicky to update. Just make sure you follow the directions. I did run into an error with it, but I deleted and reinstalled the app. As was well again. If you go fully into the software and create an AXS account, it will track a lot of data for you. This is how I quantified how much I shift. On a typical ride, I shift as much as 400 times. There is other stuff too and no doubt SRAM is gathering data for use in other products and systems.

Issues - I had a few questions. SRAM tech answered the phone and helped me.

Ways to improve - Sure. Replacement of parts if it really gets damaged. A core charge program maybe. That makes its lifetime part. For $700, many would sleep better at night.

Final Thoughts

Is it worth it? That's not for me to decide. I do like it and don't see myself moving away from it. It's been super reliable and fun to have. Sure it carries a high price tag and should. It's an outlier product. Better than a mechanical system? Yeah, I say so. Going to change your life? I hope not. Worth a look? Absolutely.
