Microshift's $600 Electric Drivetrain Is Nearly a Real Thing - Taipei Cycle Show

Taipei Cycle Show


One of the more interesting finds at last year's Taipei Cycle Show was Microshift's electronic drivetrain that they said would cost around $600 USD when released. It sounded promising, but it also sounded like one of those things that wouldn't actually happen. An electric drivetrain costing roughly a quarter the price of Shimano's Di2 XTR setup? Fat chance, I said to myself at the time. But it turns out that Microshift didn't just have a 'pig in the window' at their booth, as they've spent the last year refining their eXCD drivetrain that is now looking very production ready. It's still about a year out, however, but they have made some noteworthy updates.

The biggest update is the addition of a clutch to the 11-speed rear derailleur, which is pretty much mandatory these days. But the clutch's resistance means that the tiny motor has to work harder to move the chain across the cogs, and Microshift found that was draining the battery too quickly for their liking. The answer, as always, is more power, so they ditched the replaceable AA batteries that were used in the shifter and replaced them with a 7.4v, 2600 mAh lithium-ion battery that's recharged via a USB cable.

The battery change bumped the already bulky shifter, AKA control panel, up in size even more, but the layout remains the same: two buttons on the shifter regulate the derailleur's action, with each button moving the derailleur in a different direction. A smaller button control setup and power-saving modes, a small LED indicator tells the rider how much juice is left, and there's a new gear position indicator as well.

And speaking of batteries, Microshift has also come up with a steerer tube-mounted second battery that is meant to be used either as a spare or to charge up the lithium-ion battery that's inside of the shifter. Running solely on the shifter's integrated power, Microshift is claiming that riders can get around 10,000 shifts with the derailleur's clutch on and 16,000 shifts with it off, which are both way higher numbers than what the system was capable of last year. The derailleur also looks much more refined than what Microshift had in their booth last year, with a slimmer appearance and tweaked geometry that lets it play nice with cogs of up to 46-teeth.

The price sounds appealing, no doubt about that, but I do doubt that the eXCD drivetrain will perform on par with Shimano's Di2 system, or SRAM's upcoming electric drivetrain. The display setup in the booth shifted okay but not great, with the required disclaimer that it's still in prototype form. That said, if Microshift can come even somewhat close to what Di2 offers for shift quality, there will surely be riders who are happy to spend around $600 USD to get their hands on it.

 I just don't understand why they wouldnt go wireless...For me the total lack of wiring would be the main selling point to go electronic. Guess I'll just start saving for the SRAM solution.
  • 32 1
 If you want to go fully wireless then you need a battery per piece of gear: shifter, derailleur, (front derailleur). That's maybe too much, or too heavy.
Then, since they have to run electrical cables, I think they dont lose that much to carry the signal at the same time.

But yes, wireless would be much more user friendly.

 I'm not sold on wireless. Do I want a heavy ass battery strapped to my mech? No, I do not. Think of the effects of that extra mass bouncing around. It works fine in the roadie world because there's no rear suspension to upset. It'd likewise probably be fine on an XC bike. But mech + inevitable pie plate cassette + added battery/receiver crap AND rear suspension? I think not.

 We already know that batteries have already been made that are smaller than a button battery, and can last some astronomic amount of time. Although, the battery business would be gone if these were released. Had they been around, for sure, wireless would make so much more sense. Sadly the world's only about money, had it not, the world we live in would be completely different. We just need someone to get around the big brand names and lead the future!

 Without wireless I really see no point swapping my analog shifting cables for electric wiring, as they have been working pretty OK for the last 25 years. And yes, Di2 shifts just that bit crispier, but not waaay better then the analog alternative. Also with 1x you lose the advantage of trimming the front derailleur, so I would prefer having to smaller batteries to power shifter and derailleur.
And on the whole weight issue: If I change my regular trailtyre (Nobby Nic) for my Alpine endurotyre (Hans Dampf) the weight of the rear goes up quite a bit more then with one small battery.

 @suravida: Completely agree. I'm using 1x11 XTR and it runs great. A few adjustments need to be made after every so many rides just from flogging it, but it does it's job, and that's all it needs to do.
I personally feel like there'd be no real benefit of electronic drivetrain until it's wireless (mainly due to no snapping cable). And I guess once you take away the weight of the cabling and any other 'analog' gear the derailleur and shifter will no longer need, a battery would weigh up fairly similar.

 @JonJonM: which is where in this system?

 @polarproton: The battery in the derailleur is where nearly all of the power is used, the piece in the shifter could be very small and replaceable every year or less.

 @CraigBrownie: if you think a button battery has enough juice to run a BT receiver and a motor that's strong enough to shift a chain with a clutch resisting it and last more than a few shifts- you're kidding yourself.

 Run the rear derailleur off a tiny alternator in the rear hub- no battery needed. This would also make it impossible to accidentally shift when not moving. TADA!
  • 3 1
 weight Sram RED Etap rear derailleur: 237gr (including battery)
weight Sram RED normal rear derailleur: 143gr

Cable plus housing weighs around 40 gr, so the wireless derailleur is 54gr heavier. If you are really afraid this will affect the suspension on your bike I would advise you to stay away from any muddy trail. Changing your rear tyre from Nobby Nic to Hans Dampf would already add 145gr...

So yeah, I'll just wait for wireless. (or actually I'll just keep on riding my 1x10 Zee with XTR shifter)

 Maybe to avoid batteries everything could have a tiny diesel generator.

 Given how often bluetooth and RF devices fall over, get interrupted connections or suddenly accept inputs from unpaired devices, I can think of a lot of reason not to go with wireless shifting. Even more than that, if your derailleur connects to other devices wirelessly, it can be hacked. The possibilities for trolling overweight, leg shaving, body condom wearing dentists who spend five figures on a bike they ride five times a year are endless... ... you know what, I take it back, wireless shifting for all!
  • 2 1
 Weight and reliability. You already set your tire pressure, sag and check your shifting before each ride...you really want to add drivetrain pairing? And then need to re-pair again three more times throughout the ride?

"Hold on guys, my derailleur disconnected, gotta re-pair".

Not to mention when you run into another guy on the same channel as you and he starts shifting your bike. That'll be fun.

 @polarproton: Tesla was able to transmit power wirelessly in the eighteen hundreds. I've been charging my telephone wirelessly for years now. The problem is it easier to come up with an excuse than a solution.
  • 5 1
 @properp: Again, weight. Any idea how much Tesla's coils weighed?

Your cell phone charger is not a valid comparison as the cell phone has to be within a centimeter of the charger to even receive a slight charge. Voltage drop across a barely conductive gas is so extreme that the only way to overcome it is exponentially higher voltage at the source. This is not a problem of engineering, it's a law of physics. That's why induction (the term for "wireless electricity") has been so limited in use. It's commonplace in high voltage transmission - the power you receive at the electrical panel in your house is delivered to you through several inductors most likely...but those are pulling 240-480v off a 13000v line in most cases. For low voltage devices it's going to be limited to 5-6cm max. Certainly we can just create higher power sources for these devices but then again you run into the problem of weight, and safety (the human body is more conductive than air - ever see what happens to anything that gets near that 13000v line and is unfortunate enough to be touching the ground?).

Cliff's notes: it's going to be a very long time before you see a wireless drivetrain that runs on wireless power.

 Or better yet, you could employ a hamster to sit on your chainstays and change the gears for you on your command (he/she may have to be strapped in place depending on how gnarly your riding is).
Then Sram would come along two years later with Soaring Guinea Pig with 7000% range and 9 picosecond shift times.
Patent pending.

 @TheOriginalTwoTone: I was comparing already created batteries that are smaller than button batteries but could power devices such as 40+ years. I wasn't talking about using a button battery. Learn to read. And, maybe don't come out like you know everything, I've worked in Uni's which have been studying and designing these types of batteries. The technologies amazing, but it won't be produced as big brands buy the designs so no one can produce them.

 Explain the advantage of a wireless system over wired?
Other than initial set up, I'm struggling. And with it comes an extra battery and higher likelihood of failure
  • 2 0
 @IllestT: I'm not completely with wireless either, but I see it's advantages. I wouldn't be using it until it's a perfect component.

Having a wireless system would mean no wires. Which means if you go on a long trip, you won't have the worry of snapping a cable and having to walk the rest.

Honestly, I'd rather to stay on an 'analog' system over any type of electrical, although I can see it's advantages.
Who knows, wireless may mean being able to connect it to your device to tune it. There are numerous benefits, but obviously at this point in time wireless wouldn't be an advantage over wired or analog drivetrains.

I think a lot of people run to the assumption that wireless must be better, simply because it's higher-tech, without actually thinking why or how is it better.

 @IllestT: People think technology is the future, which is obvious the way we're heading. BUT, there will always be somethings that are better off manual/analog, for example drivetrain. Would you rather have a battery you have to worry about recharging and the possibility of running out mid-ride, or just a wire that needs replacing once or twice a year at most? I know what I'd choose!

In regards to wireless though, one day I'm sure they'll nail the design, which may, or may not have benefits over current designs. Or perhaps derailleurs aren't the way of the future at all!

 If wireless is so great why not have someone invent wireless hydraulic disc brakes, and then a wireless dropper post too! As much as I love the thought (and the looks) of a bike without any cables floating around; the cost, weight, and additional things to go wrong just doesn't make it a good option for the average biker.

Far from it. I look forward to the day I can get XT Di on sale. I finally have a frame that can run a FD again.

After a few that were 1x only. I can't wait to run DI with Synchro shift.

 @TheOriginalTwoTone: you seem to be changing opinions mate.

These are my thoughts, as stated above:
- Manual in my opinion, are better AT THIS MOMENT IN TIME.
- This is due to there not being any batteries, or technical difficulties to go wrong
- Technology will only get better with time, so I do believe that one day, our drivetrains will all be fully-functioning, well made and electronic.

 What the hell is the point of this?? I have an XT shifter and derailleur from 1995 on my city bike which I ride 50-60 km / week all year in every weather and despite virtually no more than 30 minutes of maintenance every 3-6 months the thing works flaulessly, quickly and precisely. It is light, quiet, super cheap and and by this point I would suppose pretty much indestructible. How is this better???
  • 8 0
 I've always thought the same thing. For as well as today's modern drive trains work I can see this electronic stuff really catching on in the mainstream until the price comes way down. When you can get an XT shifter and derailluer for about $130 and it works perfectly, the average person isn't going to spend 6x that for the electronics.
  • 13 1
 I'm sure someone from the 50's would think that their bike is perfectly fine and your 1995 mech is utterly needless. And so on . . . . It's why you have a mech in the first place. If people didn't bother trying new things out you wouldn't have your wonderful mech to bring up here.
  • 2 0
 From people I know who've tried it the shifting is superior and that is reason enough for rich guys / pros to want it. I watched a show on how super cars have such advanced transmissions that they in some cases won't sell a manual cause a human couldn't perform as well. I think this is similar in that the timing etc. of the shift is "smarter" than a human when it comes to shifting. Maybe I'm talking a bunch of nonsense, though. I'm more than happy with cable XT.
  • 1 0
 Electronic shifters can work differently for every gear instead of having a set leverage ratio and motion across the entire cassette. A mechanical derailleur has to make more compromises to work work on a 12t and a 40t. They can be adjusted to compensate for a bent hanger after you tag a rock and still work in all of the gears. The shifts are quicker and performs well within a larger torque and rpm range.

 @nprace - You disrupter you! Trying to expose the whole shenanigan or something?! +1000 props. I get electronic for high end stuff that works flawlessly, but $600 to be adequate at best, probably lower performing that good cable-actuated, and more susceptible to weather, etc.? Unlikely.

 @number44: A whole lot of 'if', 'probably' and general assumptions that have no evidence.
  • 1 0
 @mgolder: You are absolutely correct. We should always be trying new things and not getting stuck or blocked at the first 'but'.
...BUT, in my mind innovation should address a particular need or 'pain' of a user or at the very least offer a significant improvement in functionality. In the case of a 1950's bike with for example no gearing the pain was getting up a hill and the mech was a huge step forward in addressing that need. My wonderful mech works so well that I have no pain or need for anything else (and it seems I'm not alone).

If the need addressed is to make shifting 1% better then that's fine, but we shouldn't kid ourselves that said improvement is any more. It's then up to each person to decide whether that's worth 600$...
  • 1 0
 @nprace: So, you have no need for something so that makes it pointless then? Given electronic shifting is quicker that right there is an advancement worth making all on it's own. Add the fact that every review of electronic shifting says it works flawlessly in even terrible conditions and you have another reason to move forward with trying the technology.

Also, as with anything, the prices come down over time. Just like with regular mechs and any other type of item you care to mention. Writing something off that is in a prototype stage with a suggested price for a first generation item is just daft.

 IF we are really going electric derailleurs, then why not have the clutch be activated via servo? It would turn off when shifting. You could also have the guide pulley move independent of the rest of the derailleur cage to get optimal chain wrap, whether you're on a 9t or a 50t

 Yes it's expensive and kind of pointless, but at least it clearly is exactly what it looks like and promises.

What I mean is, at least it's not some horrendous new fitment that promises to revolutionise the mtb, but is just a cynical industry ploy that forces the purchase of a whole new bike (cough "boost" cough), or a #enduro specific bull$hit whatsit must-have, or an unrealistically expensive yet massively marketed by the cool kids thingy (cough "Enve" cough)
