5 Details About SRAM's Wireless AXS Components

Feb 7, 2019
by Mike Levy

After years of rumors and Instagram teasers, SRAM's wireless Eagle AXS mountain bike drivetrain is finally a real, live thing that will be on the shelves this coming April. 12-speeds, a few batteries and circuit boards, and most notably, no cables or wires to be seen. Instead, you push a button and the shifter tells the derailleur what to do via an encrypted wireless network. An impressive amount of work and technology went into moving the chain from cog to cog, but all you'll hear is a soft 'vvvvt' sound as it all happens between your feet.

It's as neat as it sounds, and also just as expensive as you'd expect; the XX1-level group goes for $2,000 USD and includes titanium bits and a carbon fiber derailleur cage. For reference, that's $500 more than mechanical XX1, around $500 less than an XTR Di2 group, and $100 more than the X01 Eagle AXS that skips the fancy materials used for the top-tier drivetrain. The wireless Reverb dropper uses the same technology, and it goes for a whopping $800 USD or more than twice as much as the Stealth version.

Want to know all the other details and specs? They're covered ad nauseam in my 'First Ride' article, but below are some of the stranger Eagle AXS facts.





n a
With six years of development behind it, there've been many AXS prototypes. This is just a select few.

#1 - AXS might have debuted a few years ago if Eagle didn't happen. It was only a decade ago that 2x10 drivetrains were supposed to be the way to go, and just six years since SRAM did the 1X thing... which, I'm told, is actually around the same time that they had a prototype 11-speed electronic drivetrain up and running. It was still very early days and the decision was made to put resources towards the mechanical 12-speed Eagle group rather than a wireless system.

SRAM says that they kept a small team beavering away on it, but who knows what we'd be riding right now if they had decided to go electronic five or six years ago?



n a
Because they're electronic, the AXS parts have to go through all sorts of certification that drivetrains without circuit boards don't require. This is the inside of the Reverb seatpost's head.

#2 - Like all electronic devices, SRAM has to have each and every battery-powered component certified in every country they want to sell AXS parts in. The certifications vary depending on the country and the device's specifics, too. What are there, circuit board police, or something? Not quite, but you may have heard of the FCC (Federal Communications Commission) in the United States that test things like electromagnetic emissions and other science-type stuff.

SRAM has a guy whose only job is to certify electronic components in different countries, which often requires ten samples and a six-digit budget. It's also why SRAM went out of their way to make sure the AXS electronics were future-proof and versatile - they don't want to have to re-certify anything.



n a
In order to control the derailleur or seatpost's functions, you need to press a button on the component while pairing it with the AXS app on your phone.

#3 - No, you can't "hack" into your friend's derailleur to lock everything out but the 10-tooth cog, as amusing as that would be. SRAM has built-in some security features to keep your ''buddy'' or pesky Russian hackers from forcing you to high-post down Deadman's hill. To control the derailleur or seatpost's action, you need to have it paired to the shifter, and in order to do that you have to press and hold a button down on the derailleur or post - you need physical contact in order to pair the devices, and the serial number, too.



n a
See that small window on the side of the derailleur and those even smaller gold-colored gear wheels? That's a gearbox, too.

#4 - The rear derailleur has a built-in gearbox, and I'm not even trying to stir the pot with this one. The tiny electric motor hidden inside the derailleur spins at something like 80,000 RPM, which is neat but also completely useless when it comes to shifting gears because SRAM needed torque, not RPM. So that's where the even tinier gearbox comes in by gearing it down and converting it to torque.

The "gearbox" is really just a few very small, very precisely cut gear wheels that SRAM says will last the lifetime of the derailleur.


#5 - The AXS derailleur has TWO different clutches. There's the now-normal one-way clutch that helps keep the chain on, of course, but there's also something called the "Overload clutch." That important-sounding device isolates the tiny gearbox from the forces of you smashing the derailleur into a rock. Internally, it's basically a one-way bearing, a friction device, and a little cylinder that slides in and out to release the gearbox from the derailleur.

It's also worth noting that the AXS derailleur is shorter than the mechanical version, so there's more ground clearance, and it offers more chain wrap to boot.

I also knew a guy when I lived in Seattle who worked at the hotel where RW was staying during a comedy tour about ten years ago. (RW was registered as Armand Goldman - very clever. Google it.) So when registering at the front desk, this guy got to talking with RW about cycling as it was known that Robin was into bikes. RW asked if there were any bike shops worth visiting, and was guided to nearby Elliott Bay Bicycles (RIP) so he could see the Davidson frame shop, as well as Gregg's Greenlake Cycles. RW returned to the hotel later in the day with two new bikes and a heap of new cycling garb.

3) Are the external power contacts gold plated as opposed to nickel?

They don't make mountainbikes so that implies why you may not have heard of them. Actually they don't want to grow too big anyway because that implies they'd have to have board meetings and such nonsense. They'd rather just build bikes. I think they're cool though. They actually employ a couple of people with cognitive or visual disabilities (including people who are 100% blind) for the more simple tasks that still need to be done like preparing brake lines, placing the spokes in the hub for the wheel building machine. As long as the bike turns out fine, I'm all for that.

 There is nothing that can't be hacked. Besides, you don't need to hack the system in order to mess with the rider using it. A simple 802.11 repeater is all you need to drop the connection between shifter and derailleur and then the derailleur will default to the lowest gear. Wireless is a terrible, terrible idea on machines that we entrust our lives with.
  • + 0
 @TheRaven: I doubt they are using 802.11, they claim the protocol is proprietary and it’s probably something closer to ZigBee than 802.11 or even Bluetooth.
  • + 6
 @shinook: Zigbee is 802.15, just a short range wideband variant of 802.11. An 802.11 repeater would be even more effective at disrupting 802.15 due to the 802.11 radio's power. They are using an 802 variant because that's the best that the tech world currently has to offer, and the only protocol that offers robust encryption. So all that's happening in this trick is wave cancellation in the 2.4ghz band.

 @FisherFreerider: Have you ever been standing and pedaling, then had your drivetrain slip? It's not a pleasant experience and definitely could result in a pulled muscle or other injury.

While not life threatening, in a XC race, in tight quarters with other riders, or on a technical section, it could have safety implications. While I doubt anyone is going to die, it could change the outcome of a race or cause someone to fall over unexpectedly onto other riders or trail features.

It'd be more likely to have implications for the standings of an event, I could see someone meddling with it during an elite competition, but not much else.

 Maybe we're the issue.

Maybe we should treat a bike like someone treats a guitar.

A cheap guitar, you'll be able to play, the Fret board won't be perfect the tuners won't always keep tune, the pickups may not be of choice but the basic qualities of the guitar will be there, and anyone who can shred will be able to shred.

Gibson has made guitars for years with electric auto-tuners and they are expensive too, and the sound beautiful, but do you need to have one?

Most people would settle for something in the $1000 - $2000 range and be perfectly happy.

For bikes new technology comes along like this and they tout it as the next evolution and step in bike drivetrains, but in reality it isn't. It's too antiquated, it's too complex to be of basic necessities to most people.

It's just going to one of those things, the pros will use it on stage and the collectors will have it locked away, shined and look at with admiration.

Meanwhile will all just keep playing the same tune as we did before.

 Most importantly you should know that no matter how much encryption there is wireless devices ARE PRONE TO JAMMING ...so I would strongly advise never ever to use this component on any kind of serious competition level. Roadies are aware of this and almost all pro teams abandoned SRAM.
  • + 3
 Why is everyone so worried about hacking of these things?

I mean sure. Almost anything wireless can be hacked or jammed if you try hard enough or brute Force secure keys.

But what's the point? It's not like there's enough money in this stuff and you can just reset to your paired phone. You could do it during racing I suppose to hurt your competitors but everyone would know really quickly if that was going on.

Most "hacking" of things happens for one of 2 reasons: 1. For fun to explore protocols and systems or 2. For profit. (For example get password and then access bank account).

I don't see any profit in hacking someone else's rear derailleur so if someone takes the time/effort to break into this its probably because they want to customize it.
  • + 0
 Just to add one more point I don't know the technical details of the protocols and security keys they use but it would be roughly the same order of difficulty probably to connect to your phone via Bluetooth and download your "private" pictures.
  • + 2
 @DrPete: Please point me to the quote that mentions "abandoned bikes" in that article. All that it mentions is that there are two SRAM sponsored teams and both are waiting for the SRAM red eTap that launched along with the mountain group.

"The big news though is SRAM stepping up its sponsorship by adding Trek to its existing support of Katusha. There are strong rumours of a new Red eTap groupset coming possibly this year, and it might also be 12-speed..."

I would not equate changing sponsorship with dropping because they are hackable. In fact, I'll do you one better by pointing to another article on that site on the topic of SRAM eTap being safe. road.cc/content/news/119275-srams-wireless-shifting%E2%80%94-saboteurs-dream

 @bsavery: You don't unerstand the difference between jamming and hacking. I am sure they are not hackable...but that is not important. Much more interestingly they are prone to jamming, which can take it out of order and that's good enough to ruin your race. If I were a high profile racer (knowing all the bad stuff that goes on) I would stick with cables.

 @IluvRIDING:

I'm not going to quote my resume but I assure you I know the difference Smile . But for the purposes of "screw up someone's shifting" there is no difference.

Maybe I'm slightly less conspiratorially minded and dont seeing someone being that hostile to do something like this purposefully. Maybe in the road scene but there's not that much money in Mt bike racing. And if you're caught...

 Sram, my friends and I ride exclusively in frozen salt mines where mechanical derailleurs work *just fine*. Does your fancy "battery" technology hold up to these conditions? Does the wireless radio operate properly in high radiation conditions? I doubt it, and I don't want to lose a shift just cause I'm riding past a small ore deposit. Personally I will stick with tried and true cables for now, but please Sram release the full specs so I know how this thing I'm never going to buy will work in my absurd riding scenarios.

 @mikelevy does it have the same clutch technology as previous 1X drivetrains? The new Red E-Tap seems to have a different speed sensitive clutch that does not rely on a roller bearing clutch.
As Type 2 and 2.1 clutches seem to lose their strength without retightening them and Type 3 doesn't seem to be adjustable as older versions this would be another useful upgrade.

 So, wait, for #3 it sounds like you are saying your phone has to be synced for the system to work. Is that true or is that just to adjust the function of the shifter keys and configure it?

That also really doesn’t address someone that can send messages directly to the mech, they seem real focused on preventing someone from messing with this system via their phone over the Bluetooth interface but haven’t really talked at all about the security around the communications between the shifter and mech. The fact they are proprietary and encrypted doesn’t really mean much on it’s own.

 Can I still ride without my phone always on ? What if the battery of the phone runs out, is there a safe mode that drops the post and shifts into the largest cog ? honestly, traditional shifting is working so well, why should I bother myself with battery life and apps and stuff. I really like the simplicity of a fully mechanical bike . . .

 I can’t wait to buy my Unno Dash frame with full AXS drive train and dropper, fox live valve suspension , drift pedals, and ENVE rims, stem and bars. I will have to sell the house, wife and kids or buy a dentists drill off eBay. Sadly I’ll still ride like a Joey.

 I didn't read every comment, so perhaps it was mentioned, but does it require that you have to have your phone with you on your ride for it to work, or just sync? I've smashed my phone crashing on multiple occasions (twice racing). That would make for a crappy time, stuck in 1st with the seat up at the top of your descent...

 1 question at the (maybe drunk from organic craft beer) designers: Who dont you integrate the battery around the bar / in the bar? If you crash you wont snap the expensive trigger... I see zero sense in that bulky trigger.

 "who knows what we'd be riding right now if they had decided to go electronic five or six years ago?"

I'll tell you: we would be riding cable actuated derialleurs, like we will in 5 years from now.

This is simply stupid; shimano's was (is) stupid, and this even more (because wireless). Seems more like a cold war/showcase thing than a real world project.

 So basically they just integrated and RC car servo onto the derailleur. A servo cost about 80 bucks retail and the nicer ones even have steel or titanium gears inside, not brass gears like the ones in the Sram derailleur. So what costs them probably less than a couple hundred to make, they sell for 2g. Quite a mark up. I don’t see a lot of people spending that much. Plus, it probably weighs more than a standard derailleur shifter combo.

  • + 9
 like alot of people I’m in no rush to get on the electronic bandwagon but I will play devils advocate / unpopular opinion here:

Point 1: Even if the system is hackable. Honestly who would really take all that time just to hack into some guys drivetrain on a bicycle (aside from a computer savy friend who might just want to mess with you). Maybe, just maybe in a high level race event someone might try and cheat by hacking the other teams drivetrain(s) but thats still the side of highly unlikely and for not much benefit.

2. I think entrusting your life with a drivetrain is a bit of an exaggeration because a mechanical drivetrain can and will fail in the exact same basic way; not let you shift gears. You can still snap a cable while in the middle of nowhere and be left stuck in a specific gear. Same result from a drained battery or failure on an electronic system.
Personally the scariest drivetrain failures I could imagine happening to me that would result in the possibility of a big crash would be; 1. Derailleur breaking off and being sucked into my wheel and destroying alot of spokes. 2. Chain snapping while mashing the pedals into a high speed jump. Both of these scenarios can happen whether or not the system is electronic or mechanical.

Long story short:
Terrorists don’t want to hack it & it won’t explode and kill you if it fails.

All that being said I’m sticking with my mechanical system for the time being, or for multi-day rides where the 20hr charge isn’t enough.
Maybe when the price trickles down in the following years will I consider it.

 Who would want to hack a shifter? There is big money in european road cycling.

More likely is jamming during the tour. It would be easy to jamb the shifting of a break-away group during a climb, or perhaps the remaining peloton. No hacking is needed, just a simple jammer.

 @TheRaven > 2 - Wireless is an absolutely terrible idea on a machine which you entrust with your life.

Whoa, you must not be a scuba diver as wireless (ultrasound) dive computers are common and is this case you DO really entrust your life with it (air left, time for decompression). A bike derailer is a joke... saves on cables to make easier to pedal. big deal...

 @brycepiwek: which frequency is it? Let's go to some XC MTB race with a jammer and have fun :-) Usually they are on ISM bands 433Mhz or 868Mhz.
  • + 2
 @brycepiwek: Obviously only a joker is going to hack into the system to mess with people. My point is that they can...and a mechanical drivetrain is not hackable.

On the second point - chains can break and derailleurs can be broken by sudden multi-gear downshifts under extreme power (like the power necessary to climb very steep technical terrain). Again, not a likely scenario, but again, far less likely to happen on mechanical drivetrains which are also cheaper, lighter, and do not need to be recharged.

The bottom line here is that a wireless drivetrain is a solution in search of a problem. Furthermore, it creates new problems where we absolutely do not need any more problems.

 @MonsterTruck: Cars have been hacked extensively actually. Ever hear of FORscan? That's hacking for a positive reason...as more and more cars become "connected" you will see more and more hacking for sinister reasons. But that's a great example because it's also a terrible idea.
