D1X Wireless Remote Shifting System


D1X Electronic Remote Shifting System

Brandon Rodgers and Devin Carlson hail from Santa Cruz, California, where they have been working for a number of years to develop a wireless remote shifting system that could shift any cable-operated rear derailleur. They founded Archer Components and set to work. The idea was to use the simplest electronics and construction that would still guarantee reliable shifting and all-weather performance.

D1X Explained

What they ended up with was D1X, which stands for ...well, you probably guessed by now. D1X is a digitally controlled-linear motor, packaged with a powerful lithium Ion battery and some electronics

Brandon Rodgers (left) and Devin Carlson founded Archer Components with the intention to eventually produce a complete wireless-shifting drivetrain
inside. The slender, sealed plastic housing, which is attached below the drive-side chainstay actuates the rear derailleur through a short length of standard cable and housing. The beta version uses a Bluetooth signal to communicate with a two-button remote shifter that mounts to either SRAM or Shimano integrated brake levers. The magic of D1X is that its user programs each shift individually using a smartphone, so D1X can be adapted to any combination of derailleur or cassette - eight speed or twelve speed, it doesn't care, as long as you tell it where the cogs are located.

Once you go through that simple setup process, you turn off the app and the internal processor has memorized your shifting sequence. Should you bend your mech, the D1X unit can be switched to repair mode, which allows you to toggle the the first shift position right or left to compensate and, boom! perfect shifting is restored. Presently, the Blue Tooth system is a bit of a battery drain, so the D1X goes through a charge in a few days, but a planned switch to RF communication (like remote car locks use) will boost that figure to a week. The D1X unit is rechargeable, but the remote shifter requires button batteries similar to those used by bike computers.

Archer is at least six months away from serial production, but at present D1X functions very close to expectations. I ran through the gears, using D1X to operate a SRAM changer, shifting an 11-speed cassette and gear changes were at least as smooth as using a manual lever, and the system operated very quietly. I also went through the setup process and found it to be quite simple. Archer's D1X wireless remote shifting system is set to retail for $300 USD. Presently, Archer is awaiting a potential funding deal while they smooth out the final details. Until they officially launch D1X, Interested riders can follow the project on their web page.

Existing remotes are still a little boxy looking, but the ergonomics are excellent.

Archer is printing the plastic housings, so they can experiment with button placement.

 the grip shift has its advantages. in some bike check video from crank works a guy with a zerode said the grip shift was nice coming out of corners because you can twist the grip fast to get it into the gear you want instead of clicking a bunch with your thumb.

 If i'm not mistaken based on the programming you could set it up for a pinion as is...

 @rclugnut: pinion needs TWO cables - but, I think you are on to something. Especially as the issue with not being able to down shift under load is the lever force to actuate the shift. The gearbox itself can handle shifting under load. Just use a lovely little strong linear motor.....

 I was already thinking about this (and didn't think to apply the idea to 1x drivetrains, so another of the 'why didn't i think of this moments') and was thinking whether a Eagle shifter could be made to work on a P1.12. I think it could function, there's just the issue of how strong the return spring inside the adapter black box needs to be in order to shift the pinion both ways...

Realistically, hands on experience with the gearbox would be needed to make this.

 @Primoz: Pinion uses two Shifter cables which is why it doesn't work with a traditional Shifter.

 @gonecoastal: you need to read a bit more closely or until the end. See, i wrote in a crucial piece of information: "there's just the issue of how strong the return spring inside the adapter black box needs to be in order to shift the pinion both ways".

I'm well aware how Pinion works. I'm not dreaming here, i'm actually thinking of how it could be achieved. And am also aware of potential issues.

 @Primoz: Shoot me a PM guys--I'd love to chat about this with you guys. The best scenario is NO spring--a linear motion device can provide positive traction in both directions and doesn't depend on a spring and cable-tension to motivate what's on the end. Eh. Burp. Brandon

 @Archer-Brandon: hey there. just want to say this look fantastically good and im so happy this is coming and i think you guys are great too. just a thought here.. not sure if anyone in the comments has mentioned it because i haven't read them all. or you have thought of but could the battery for the system not be charged by a dynamo or some sort. ? from each of your pedal strokes you charge up. but its not creating drag on the drive train when you freewheel. so for instance, it will be on and work when you pedal but you could switch the system around, to be working when freewheeling instead of pedal strokes.. the reason i think this could be beneficial for the shift mechanism that operates the derailleur , well its batteries we all know as soon as they get low stuff doesn't work as crisp as at full power, simply because it cant give reliable and consistent operation like we could with a wired setup. also i know the battery liife is good but what about when the power is low or gone? like if some was doing the mega avalanche or just far away from a power source. to be quite honest as well i would'nt want to be worring about that. have to detach it every night to get charge. i know your going to change to rf to give it more longevity too. so basically my thought are here for you, or is this all irrelivent because it not reliant on the battery? hopefully it makes sense to you guys . but having said all that i love it and i want one. thanks

 Totally. I've had to change my cables like once in the last few years. And even then, my gears were shifting, just not super well. This electronic stuff makes no sense. Have to charge your shifter once a week? And if you don't, you legit can't shift at all? I'll take my rusty cables, thanks.

 Seriously, why ? What is the point of electronic shifting to begin with ? Modern drivetrains/derailleurs are incredibly fast, smooth and reliable, don't need to be powered by batteries, that have a bad impact on the environment from the building process to the disposal of the ones who's life cycle has come to an end. Electronic shifting isn't going to solve wear and tear problems on your cogs/cables/chain, or a rock smashing your derailleur into your spokes. Why this electronic absurdity ? I really fail to see the point here. This is a "nonvolution". How frustrating must it be when you want to go for a ride and realize you forgot to charge your f*****ing battery ? How about it's autonomy in cold weather ? Electronic shifting simply looks like the one thing I will never, ever buy.
  • 10 1
 Electronic shifting allows precise shifts every time, no matter the conditions. It provides an element of set and forget as you never need to adjust them
  • 11 0
 @cliffdroper From my personal experience, I'd say that electronic shifting is great and it's hard to go back once you ride it. I was skeptical, in the same way that I didn't understand hydraulic brakes at first... my cable brakes work fine, why would I change? I thought the dropper post was a total gimmick too.... but it's ended up being a game changer. I'd put electronic shifting in the same group as those other two examples.
  • 7 0
 @filmdrew: Well stated, tough to understand something until you've tried it. Even tougher to try it without a clouded judgment and expectation bias.
  • 6 0
 @rrsport: maybe I'm really lucky or something, but I ride with an XO1/XX1 drivetrain combo (1x11) and haven't had to adjust it for the last two years, so that's that in terms of set and forget. The shifting is very precise and smooth, whether I ride in muddy or dry conditions. Maybe electronic shifting is indeed faster, which at this point must be a matter of milliseconds, a difference that I cannot pretend will change my global riding performance. Maybe Absalon feels the difference, but it looks like Schurter still rides reasonably fast with an old mechanical cable actuated drivetrain. I guess if you like to ride 2x10, then electronic shifting like Shimano's Di2 that automatically shifts through both front and rear at the same time might be handy, and actually, be a new riding experience, but I really fail to see a proper 'game changing' benefit of it on 1x set ups.

@filmdrew I see what you mean, but I was dreaming of hydraulic brakes as a kid, long before I could afford them and as soon as I heard about dropper post I was hysterically enthusiast about the concept, as in both cases I could really sense the difference it would be able to bring to my global riding experience (actually slowing down and not having to lower and lift up my saddle repeatedly on most of my rides). Same thing with 2x and later 1x setups, bigger wheels (I know...), tubeless setting, shorter stems etc. So I'm really not one of those conservative mountain bikers who sees any changing/evolution as a probable useless marketing BS that the bike industry is trying to force us into buying.

So can I admit there is a difference between electronic shifting and high end mechanical shifting ? Yes, technically, there is one, that can be measured and calculated and maybe even actually experienced whilst riding.

Do I think that it's benefits outweigh it's deficits/disadvantages ? Certainly not, as I'm more than reluctant to rely on electronics and electricity powered devices to be able to ride my bike. Not even mentioning the fact that if the electronic fails, on the trail side, you're basically just f****ed. Like modern cars.

Maybe I'm paranoid, but I can see this as one step further towards an automated mtbike, that will, in a few years from now, analyze the terrain you're riding and shift automatically, change your suspensions settings (I know I know, this thing already exists) and lift and lower your dropper post accordingly, and maybe even pull your brakes for you as you're getting close to a certain speed at a certain angle. And that wouldn't even be the ebike version... The car (and motorbike) industry is already aiming towards these concepts, so believing that they won't eventually be implemented into cycling, might be a bit naive. Still, some might look forward to these days... Call me a hippie or whatever, but I'm still one of those riders that is simply mesmerized by the level of precision, technology, comfort, pleasure, quality, toughness and velocity that modern mtb bike builds have achieved, relying solely on man powered mechanical concepts.

 @cliffdroper: what super cables are you running on you bike that XX1 works flawlessly after 2 years without being touched? We have the hardest time getting brand new ones to work out the vox! And I'm not hating, I have XX1 and it's always needing tweaks. Sram gears are the first to freeze up in cold weather when Shimano will work. They hate friction in cables. They are fussy beyond words. Unfortunately, this electronic system is not di2 and there for still had the worst part of a cable system. The bit that picks up the most dirt and moisture. The bit that affects shifts the most. So, though in principal this should make for wonderful consistent shifts at first, a bit of dirt and moisture will still render the system flawed..

 The advantage of electronic shifting is the lack of cable and a motor initiating the shifts ensuring reliable shifts in muddy conditions. This doesn't allow any of that so whats the point?
  • 5 1
 I mean a shorter cable will develop less play from stretching so there's that.
  • 6 2
 Well, it's a much shorter cable, so less build up of grime to contaminate the shifting. But, I think the point is, that considering that you can program the shift distance to go 1 gear at a time, then surely there is the possibility to program it to shift 5 or 6 gears at a time using a BOOST button (see what I did there?) That would save all those clickity clickity clicks. And it's cheaper than fully Di2 upgrading your bike.

 It would allow you to run gears on a dedicated SS frame without cable routing. Other than that and modifying it to run a pinion without a gripshift I dont see the point.

@rwb500:

Problemsolvers makes a derailleur mount for SS bikes, I've seen other companies as well.

I looked into it researching commuter bikes as surly 1x1s can be had for relatively cheap. I'd need gears, though as my commute is long and hilly. Ziptying a full length cable housing along the frame is your best option at this point.

So WHY getting the bike industrie in this gimmick ?!

 Pretty much. I still prefere 3rd party making add-ons to traditional systems than having manufacturers force it on us though. As far as I am concerned, it is adding a layer of complexity to the most unreliable area of mountain bikes, no thanks. Another example of fixing a problem we don't have. Motorcycles have a lot more electronics and they still mostly use cables for the clutch.
  • 1 0
 Can someone tell me if the high dollar electronic shift systems continue to use the spring inside the derailleur? I assumed they did away with that to minimize the mechanical load on the system. Here the D1X uses the derailleur unmodified, so battery drain on the system pulling on the massive spring load of the derailleur.

 I have to say, I hate E-shifting, mainly because rear derailleurs are so exposed and i break them fairly frequently. the thought that i would spend a ton of money on e shifting for it to just get smashed on a rock.... ridiculous. With all that said.... this is great. I can smash my derailleur and just but a cheap new one as the e receiver is separate and pretty well protected. but anything that can make shifting a bit more smooth, i am for. I am curious to see if it can auto adjust to account for cable stretch. So... well done there, I'd consider buying for sure. My other issue is running out of battery.....
  • 1 0
 Assuming this could be used to operate any speed drive this would be awesome and future proofing the need for different shifters. It would be cool to only need a rear derailleur on every bike in the stable assuming this system is easily transferrable and set up.
