Most bestest shifting

  • Familiarity: I've put it through the wringer

Have run X01 for the past 3 to 4 years and have never had any shifting issues. This derailleur rocks and I probably will continue to always run X01.

Much better than the 11s. Everyone is always saying it not, but just switch to 12 already if you haven't. Shifting is super easy and reliable, and this thing is durable. Keep things maintained and this thing will stick around for quite a while. Amazing stuff.

That dog will hunt

It shifts so clean and crisp. Why would you ever go GX?

V nice

  • Familiarity: I've put it through the wringer

Great derailleur - function is top notch, it's easy to install and easy to maintain. 10/10

spot on

  • Familiarity: I've put it through the wringer

Shifting is great, holds up well, minimal maintenance, highly recommended.

Best of the best

Eagle is really dominating the drivetrain market right now. XO1 is the best of that market

shifts as expected!

    Love the x01 eagle. Shifts great and has a great range. Deff going to put on my next bike as well.

    SRAM Win

    • Familiarity: I've put it through the wringer

    Top Notch Performance from SRAM, vast improvement over 11spd version. Easy install.


    • Familiarity: I've used it several times

    I went from a 32 in the front on my 1x11 to a 36 in the front with eagle and the math says I still got an easier granny gear. Nuts!


    • Familiarity: I've used it several times

    So far it has worked great! I already have a pretty big scratch in it though. It hangs super low and would be quite easy to tear off if not careful. I am super happy with it though. The 1x12 is the way to go!


    • Familiarity: I've used it once or twice and have initial impressions

    12 speed is the future. say good bye to your front mechs, they are a thing of the past. This part is fantastic quality, and shifts flawlessly!

    1x is the way to go for mountain biking. I cannot tell you when the last time I dropped a chain was (I do not run a guide either) When I was running 1x11 I always ran a 28t chainring. I am not a stellar climber and needed something I could slog up the mountain for 2 hours of straight climbing, and I am not a world cup enduro racer, nor do I care if I spin out of gearing on some fire road descent. There were only a handful of trails, or sections of trails where I could have used a taller gearing so that I would not spin out. Enter the Eagle! I run my eagle drivetrain with a 32t chainring, which gives me slightly easier gearing than my previous 28x42 setup, but I have yet to find a section of single track where I could run out of gears. I could not see running a 30t chainring with Eagle unless you are longing for the gear range offered by the old school 3x drivetrains. I love the responsive and consistent shifting that Eagle brings to the table as well. Well done SRAM, looks like you are always at least a step ahead.
