Good morning! Shane - thank you for testing our power meter and the work put into the preparation of the film. The result of the test surprised us. We see that something went wrong and we are already working on diagnosing the problem. At the moment we are checking all factors that could have influenced the incorrect analysis. We can not yet give a clear answer to the question what has failed, but we do not exclude that you have passed the wrong product for testing. We will check everything and certainly explain the situation. Once again, thank you for reliable analysis and we ensure that we make every effort to ensure that our customers receive the highest quality power meters. They are designed by experts and active athletes for athletes! Therefore, we can not afford such situations and we will certainly explain it thoroughly. Dzień dobry!

"we do not exclude that you have passed the wrong product for testing". What does that mean. Only faulty devices goes out to customers who don't do extensive tests or is somewhat challenged to prove the same results as Shane ?
Once I'm a day or more in, I have to keep going or it's just time wasted. Three days... and trying my best to get this reading right... today did my head in with zero-offset roulette.
Another great testing effort! I really like the PIN access control, the app graphics, and the price isn't too bad. I don't like the frequent calibrations and the overall results are not so encouraging. I notice that InPeak responded to your concerns publicly and appear to be on the case so it will be great to hear what they have to say about it, and maybe ship you another crank, should you be interested in going through it all again. I can't help thinking that crank-based power meters are a bit of a rip-off though: the cranks are cheap (~$80 US for an Ultegra R8000 left crank in single unit shipments) and the electronics should be pretty straightforward off the shelf components (no FPGAs) - and cheap - so long as ANT+ and BLE are supported. Then all you need is to accurately bond in the strain gauge - also cheap - and provide the software to do the sensing, calibration and interpolation. (I know, hand wavy...) These two items are obviously where the cost and expertise come in. Seems like an excellent opportunity for a bit of open-sourcing. But maybe the setup, calibration & conformance require a physics department or facility able to accurately load and test stresses on the cranks. I wonder how many get sacrificed because the bonding wasn't correct, or the readings are just too far outside of allowed tolerances? Wishing that Shimano could get their act together on this seems to be asking too much, especially at a "reasonable" price.
Hey Mr. Miller just wanna say here in Boston USA you’re Videos are Wicked Pissah Cool! You’re Video on the Di2 helped me make a decision to buy a new Road Bike a 2019 Speclized Tarmac Pro w/Ultegra di2. Thanks again keep rolling out those Wicked Pissah Cool Video’s Very helpful to none Pro Weekend Warriors who love the sport of Cycling!
Another useful review SHane, thank you, and one more power meter choice to cross of the list of possibilities. I know its a different price bracket but I am becoming more and more convinced that QUarq Dfour 91 will be recieving my hard earned beer tokens very shortly.
If only the looks would be more like the Dura ace. I think it looks a bit out a place on a Dura ace groupset. And you have to change the BB to Sram. I'm not sure which one to get... But the quarq is on top currently.
Wow! So much patience for doing all the testing the manufacturer couldn't be bothered to do. Sad that companies still ship products that obviously aren't ready.
Just watched this one after you mentioned it in a comment some days back. I see there is a second one so will have a look at that one next. Watching this one in was like ... where is the good you mentioned so I could only assume that the next vid will shine. Thanx as usual for being the cycling g o d it there for the masses as you are doing justice for all cyclist out there
Have you ever done a review on the PowerPod? Really interesting concept, looks a nightmare to set up with the Isaac for mac program but from what ive read the data is very good for its price point of €300 ish...
DCRainmaker did a good review on the powerpod. I had one a bit ago and they've recently updated the calibration routine. You no longer need to plug it into Isaac before calibration and it's only a 6min ride now. Still need Isaac for intial set up but after that there's no need to use it really if you're only using it outside on the one bike. Can be used on a trainer and with multiple bikes (4 I think). Crazy clever bit of kit and it does seem to give accurate numbers, especially considering the price. I only changed because I picked up a unused gen 2 Stages for silly money and only need a pm on one bike.
I’m assuming that temperature doesn’t play a factor here. Was it better in the heat vice the cooler indoors? Since it has active temperature compensation , it would be interesting to see if that had anything to do with it going out of calibration.
You mentioned how it's ideal to test 3 power meters to get a more accurate comparison. I have my 4iiii, my Direto, and now a pair of Assioma Duo. I'm trying to figure out if I can do this with one head unit an iPhone and let Zwift record the trainer? Or do I need 3 head units?
Price for 105 5800 left crank powermeter is 366 EUR + 9 EUR shipping cost. Why should I spend 375 EUR for some unknown powermeter from Poland, while I can buy stages 3 for 350 EUR or 4iii for 300 with next day delivery and local guarantee? InPeak, at this price point you won't get any market share.
That's a shame for this PM being so off. BTW how sure are you that Assioma's are accurate? I saw stages on right crank, maybe you could compare with that as well just to be sure. But more I look at graphs more seems like their app is not calibrating well. And thanks for listening my comment to break Assioma into UNO. Makes it more clear to compare :).
Multiple reference points to be pretty confident with the Assiomas. The Neo 1 which the Quarq (static calibrated) agrees with, Neo 2, Kickr, Direto, etc, all agree with the Assioma. The Stages Right is documented in my video on the L/R video on that unit. Until I have a PowerTap G4 disc hub, they're my go-to out on the road.
Real pity, was hoping for better results as well. And looking to their duraace ready crank it costs 575€ in EU. Way too high price, rather recomend Assioma UNO (its 130€ cheaper) or DUO through some good deal.
Cheers. And thanks. I really don't like doing these videos where things just don't work.... I'd rather everything was ace. I need a few long rides to drop the past few days behind me.
@@gplama You're just doing an honest review. If it makes you feel any better I just ended up buying some Mavic Open UST Pro rims to build my first set of wheels even after watching your video where you had so much trouble with tubeless. Have a great week! P.S. - I am curious to see what you and Ray have to say about the new Power2Max power meters, both the 1% claimed accuracy ones and the NGEco ones. No calibration on some?
@@AaronGoodTimes Power2Max are hard to get a hold of.... apparently. They were a no-show at Eurobike and Interbike 2018. People say good things about their units.
@@gplama I am going to hold off on a new bike until you get a chance to examine some. Maybe by the end of 2020 their products will be more available for testing. I hope you get some time for riding for fun in the meantime.
Shane Miller - GPLama thanks Shane. I checked website (which I did after posting my question). They say 30-40nm 😳. That's huge. I usually just snug up my pedals. Is that what you do too or do you go to an exact torque. I think my Ultegra say 12-14nm

Please help me. If you were to buy a dual-sided power meter today, which one would you buy? Price is secondary to performance/quality but not irrelevant. Thanks!
Entirely your call what to go with. The videos I’ve uploaded give a good indication of what the user experience involves - Power meter type, installation, setup, use, features, accuracy, etc. There’s no ‘best’ for everyone, or clear leader.
@@gplama and so not the answer I was looking for X'D But sure, I'll go through every video. On the topic though, I am a backer of dual IQ2 powermeters and their latest updates indicate that they are probably going to fail to deliver their product in the way it was originally promised. We backers now just have to wait and see what kind of product gets delivered if any.
Case in point of telling people what to buy... if I had said “buy IQ2 it looks amazing” then imagine the heat poured on me given their current state. I will however tell everyone to keep away from the new Arofly Kickstarter.... which is likely to involve them sending me a nasty email. In a way, I’m in a no win situation..... This is why sticking to the data and my experience is best for me.
It honestly gives me anxiety riding power meters that do this. Thankfully the Assioma kept it real with the Neo indoors, so I wasn't going crazy. I also know I'm not in the 370W zone up the hills today too. ;)
In their defence... this thing was brilliant... twice. If that's how it was tested for QC then that'd explain it. As to why it swings so wildly between zero-offsets is a mystery.
@@gplama but was it? being good for sections of a few rides does not add up to brilliant to me... you had 4 rides all with bad data..... not 2 good rides and 2 bad ones.... all were bad

Best power meter for zwift
I’m assuming that temperature doesn’t play a factor here. Was it better in the heat vice the cooler indoors? Since it has active temperature compensation , it would be interesting to see if that had anything to do with it going out of calibration.
Temp. is a factor for all strain guages as it impacts expansion/elongation/deflection as does applied force/torque.
You mentioned how it's ideal to test 3 power meters to get a more accurate comparison. I have my 4iiii, my Direto, and now a pair of Assioma Duo. I'm trying to figure out if I can do this with one head unit an iPhone and let Zwift record the trainer? Or do I need 3 head units?
In theory, yes.
