Video: SRAM's Wireless Eagle AXS Drivetrain Explained


SRAM Eagle AXS Quick Hits

Is this stuff waterproof? It is, at least as much as a mountain biker would ever need it to be. The components come with an IP69K international standard rating that validates systems that require regular pressurized cleaning. Lake jumping? No. Spraying off mud? Zero issues.

How long will the batteries last? That depends on how much you shift, of course, but SRAM says to expect 20-hours (or more) from the derailleur's power supply and two years from the CR2030 that's in the remote.

Do you need to download the AXS app? If the last thing you want on your phone or iPod is another app, then no, you don't need it to use the AXS drivetrain. But you'll need it if you ever want to play with different button settings.

Is my drivetrain going to get hacked? Highly unlikely, but that tinfoil hat does look good on you. The shifter and derailleur, as well as the Reverb AXS and its remote, all talk to each other through an encrypted wireless network that SRAM says is proprietary to them. In order to change the functions, you'd need to have the app, know the targeted derailleur's serial number, and have physical access to do the pairing. If your riding buddy does all that, I think he deserves to be able to play a prank on you.

What's this Eagle AXS drivetrain compatible with? Any bike that can run a normal, 12-speed mechanical Eagle drivetrain can be AXS-ified as well. You'll have to use the now common XD driver, of course, but that's it.

What does the Eagle AXS group include? You'll get the AXS derailleur and shifter, and it also comes with the cranks, chainring, cassette, chain, charger and cord, and the Chain Gap Tool so you set it up correctly. Oh, and some batteries, of course. Interestingly, SRAM is only offering the group as a whole kit, for now, but I'm told that individual components will be available around four weeks from now.

What's up with that rainbow colored chain and cassette? I think it looks neat, but it isn't going to be for everyone. AXS XX1 will only be available in what SRAM calls "oil slick" but the slightly heavier X01 group can be had in a more subdued black finish.

Batteries surely mean that it's heavy, right? The batteries weigh just 25-grams each, so not really. An Eagle AXS XX1 group is said to come in 5-grams lighter than its mechanical sibling, putting it at 1,451-grams without a bottom bracket. X01 is 15-grams lighter overall, so it weighs 1,487-grams without a bottom bracket. SRAM declined to provide me with individual component weights.

When is it available and how much should I sell my organs for? The roadies will be able to get their AXS components pretty much today, but us dirty mountain bike types will need to wait until sometime in April before it's on the shelves. An entire Eagle AXS XX1 group will go for $2,000 USD, while the X01 group sells for $1,900 USD. You should probably just save up instead of selling your insides.
