Decoding Shimano’s New Power Meter Pedaling Metrics


As first reported by Cycling TipsShimano has launched their complicated pedaling metrics, referred to as Force Vector (no relation to Garmin Vector, additionally an influence meter that first displayed drive vectors). This is now to be had as a instrument replace for his or her R9200P Dura-Ace and R8100P Ultegra persistent meters.

However, as appears to be par for the direction in this educate, this implementation looks as if a scorching mess. I do not believe even I can have predicted how horrifically this whole transition would move when the Shimano acquisition of Pioneer was first announced a few years agohowever this has surpassed even my wildest expectancies for failure.

And after last summer’s mess, the ones expectancies have been raised beautiful darn prime. Fear now not, they have been toppled.

The Process:


First up is attempting to decode the 28-step procedure for making this paintings. And to be transparent, I’m now not being sarcastic. There are actually 28 steps to get this working, however as I’ll display, even this is an undercount. Nevertheless, “Quick Startup” used to be used within the identify.

At first, it’s possible you’ll assume it is simply 3 steps, however each and every three-steps are subdivided into upwards of a dozen steps, with uncounted sub-steps inside of each and every of the ones.


Thus if truth be told, together with the ones sub-steps (a few of which come with 5-6 steps), you are at just about 50 steps to get this operating. Plus, do not disregard all of the not-so-little caveats above too. Start the timer too rapid? No drive vectors for you!

Of direction, I do not have an R9200P persistent meter to check this out. Nor to check whether or not the R9200P or R8100P persistent meters are correct in any respect. Despite guarantees final summer time, then fall, then wintry weather, for a unit to check, Shimano’s long gone silent on that one (and apparently long gone silent on check devices for each different media entity). But hiya, possibly some motorbike store within the Amsterdam house will let me check trip one for per week or so?

In any case, it seems that that Shimano principally took Pioneer’s older drive vector pedaling dynamics after which shoved it into their more recent R9200P Dura-Ace and R8100P Ultegra power meters, by way of firmware replace. The structure and formatting seem the similar, and the truth that present Wahoo devices paintings with it sort of feels to suggest that not anything’s modified. Wahoo previously partnered with Pioneer to enable their pedaling metrics there,

Now once more, deciphering the huge instruction set uncovers some super-interesting issues:

1) Enabling the pedaling dynamics disables the ANT+ broadcasting of persistent/cadence: This additionally suits with what Pioneer did 4 a long time in the past, wherein it broadcasted out on private-ANT, disabling the open ANT+ connection. It used to be ludicrous then, and it is simply as loopy now. This diagram makes an attempt to provide an explanation for which settings you need to use. But the important thing factor you want to grasp this is that the “Bicycle Power” choice over ANT+ is going away whilst you allow Force Vector.


2) Fear now not, Bluetooth to the rescue! Now, with the intention to take care of the truth that they flip off the ANT+ persistent meter profile, they as a substitute broadcast persistent and cadence over Bluetooth Smart. The idea at the back of that is that it lets in your motorbike laptop to nonetheless get the facility/cadence knowledge. And in observe, that is kinda true.


Except, when it is not. See, they checklist the Edge 520 Plus & Edge 820 as suitable with the brand new Shimano CIQ App (extra on that during a 2d). And I’m certain that is true. Except what is additionally true is that the ones devices do not toughen Bluetooth sensors (simply telephones), so, a person can not in fact get their persistent knowledge this manner. So actually, you’ll’t get your persistent knowledge for an influence meter recorded for your head unit. But you do get beautiful arrows recorded, however the ones may not display up in any right kind persistent fields.


3) The Connect IQ App! Now, excellent information, there is an app from Shimano to show and save this knowledge. they have released a new Connect IQ app that principally acts like a Pioneer head unit would. And to their credit score, that is beautiful nifty. I imply, now not as nifty as simply supporting the prevailing ANT+ same old like Favero or Garmin did, however hiya, it is a shut 2d position (in a box of 2 competition). Which is not to mention that ANT+ Cycling Dynamics would duvet exactly what Shimano is attempting to seize. So I in fact do not begrudge their advent of an app right here. I believe it is foolish, sure, however tremendous. They simply created further paintings for themselves right here. Regardless, I do very a lot recognize they don’t seem to be seeking to have other people purchase in a different way old-fashioned motorbike computer systems. And, as soon as all is claimed and completed, the whole lot will get transmitted to Shimano’s platform. That stated, as Shimano warns in their FAQtheir self-imposed requirement for twin private-ANT & Bluetooth Smart broadcasting of your knowledge will lower battery lifestyles.


4) Or, Wahoo integration! Of direction, because of Wahoo’s present partnership with Pioneer from years in the past, that helps it natively. This comprises each show and recording, which then transmits it to Shimano’s platform at the back of the scenes the place you’ll analyze it. Again, even supposing Wahoo does not toughen the ANT+ requirements right here, I recognize that they did one thing right here (and left it right here), to make use of. Plus, as a good thing about that present dating, you do not have to pair up your persistent meter (once more) as a Bluetooth instrument. Wahoo is in a position to decode it from the proprietary Shimano/Pioneer knowledge move.


5) Magic Arrives: After you will have finished your trip, the usage of a supported Garmin instrument + CIQ app, or a Wahoo instrument, you’ll be able to save your trip and it’s going to get mechanically uploaded to Shimano’s internet platform.


You can use this web page to research your knowledge and do different issues. Note despite the fact that that none of this drive vector stuff is viewable any place else, as it does not practice any requirements. Though, I believe handiest TrainingPeaks/WKO has completed anything else with Garmin’s Cycling Dynamics in any case. So that is almost certainly now not an enormous loss in keeping with se. And in fact, that ignores that apart from for motorbike becoming or damage restoration functions, I’ve but to peer any real-world utilization for pedaling potency metrics in coaching or racing (together with Garmin, Favero, and so forth…). Even Wahoo stated precisely as such when they launched their power meter a few months ago,



So why hassle to jot down up a submit about Shimano’s persisted confusion on this area? Well, to show that it is not excellent sufficient. In the similar means I identified final week that Garmin’s RCT715 Varia Camera Radar wasnt excellent sufficient. When main firms on this area fee you massive quantities of cash for his or her merchandise, they will have to upward push to a undeniable stage of acceptability and capability. Else, you should not purchase them.

The Shimano persistent meter fiasco remains to be a type of examples. We nonetheless have no idea if the brand new persistent meter fashion is in fact correct but (indicators most commonly level to no, however the knowledge is skinny). But beginning these days, Shimano will without a doubt get started promoting those new pedaling metric options. Except, it is necessary that individuals perceive what a multitude this selection in fact is – particularly in case you are on a Garmin unit (on this case, thru no fault of Garmin, they are simply the FedEx guy right here).

Perhaps Shimano will repair it, however almost certainly now not. But we mustn’t praise firms with cash for doing issues poorly. Not Shimano, now not Garmin, now not GoPro, Wahoo, Apple, Samsung, or any individual else. No merchandise are best, however this

There are excellent causes to shop for Shimano’s drivetrains and motorbike portions. I’m the usage of the R9200 (sans-power) on a special motorbike and it is nice. But purchasing the facility meter variant? I’d be saving your cash and spending it in other places. Except for IQ2, do not spend it there.

With that, thank you for studying!
