Been my first powermeter for 4 months now. Works great and data seems to be roughly consistent with the two trainers that i had. Battery life seems great too!
The P2Max was one of the very few options for my fat bike. The extra big battery is a bonus for me in that my winter races are very cold. Last year during my A-race (Alaska Frosty Bottom) the temperature reached -15F/-26C when my Wahoo Bolt computer died (even with an aux battery pack supplying power), but my P2Max kept pumping out data right to the end. I agree the rubber battery cover is a weak bit. It feels like it could come off easily, but in three years of use, it has never come loose or fallen off.
After using my FSA Powerbox Carbon on my triathlon bike for 3 years. All I do is change out the battery the night before a race, verify its connected to my headunit pre-race, and have fun. It’s been absolutely 0 fuss or problems, and it just simply works. I love it, I’ll get another one for my next TT build honestly.
Always thought the P2M was a good pm, great to have that confirmed! Battery cover - my friend has ridden two full CX seasons here in the UK (so aweful conditions...) and myself one season using the P2M ngeco. Not one single issue with the cover and they got a lot of abuse in that time!
I am a Shimano Ultegra 6800 user who has have recently bought this ngeco power meter and rotor aldhu 24 crank combination. This review of Shanes was a big factor in my decision. I am extremely happy with the accuracy and quality of the product. I have specific fit issues which prevent me using Faveros. I still wanted a power meter that allowed me to keep using my current Shimano bottom bracket and current Shimano chainrings. Also, it had to be ACCURATE. Prior to the power2max I been using a 4iiii left-crank-leg PM with a poor quality strain gauge that broke after 18 months (as did several of my friends), then a Pioneer left-crank-leg power PM which either under or over measured power, thus inaccurate. Both were measured against a Tacx Neo first generation. I'm happy to say that the Power2max is accurate. It perfectly and repeatedly matches the Neo in both power and cadence. Its very easy to install and simple to use. I'm also happy that if I ever upgrade to 12 speed Shimano, I can continue to use this same power meter, as it fits all 11 and 12 speed Shimano chainrings. Somehow Shimano can't even offer this level of compatibility with their own cranks. A tip for anyone considering this product and wanting to save money. There is a lower cost crank arm option called "Rotor Vegast 24" which is only 60 grams heavier. Power2max also rebrand Vegast 24 arms with their own logo and sell as a combination with the ngeco spider.
Thanks Shane...am considering one of these for my next build as I am also considering Campy Super Record 12S and I can buy as a complete Spider and Crank
I use the NGEco on 2 Bikes. One with the FSA Powerbox Alloy (as OEM Integration) and the new Spider for Shimano XT (MTB) and both work excellent. Best Powermeter so far. Switched from Assioma Duo because I changed my Road for a Gravel bike and and the assioms wont run with Standard SPD. As always really excellent Review!
@@Elias-jo1cc It's been real good no complaints, no drop outs, reliable, good tool. But I can't say much about reliability or durability since I haven't had it for too long.
The NG Eco is a great power meter, I had one for over 2 years on my Sram Force 22 bike, ran perfectly, simple to use, no calibration, just get on your bike and ride! Battery lasts 250-300hours as advertised. The install on the Sram was great as only the stock spider needed swapping out. After getting a new bike with Ultegra Di2 I went for Favero Assiomas as I didn't want to swap BBs on a brand new bike, ran both power meters for a few rides and never saw more then 1-2W difference. Sold the Eco to a friend and have been running the Assiomas happily for the last few months. Thanks to Shane and Ray for their reviews and recomendations :)
I use this powermeter with the Aldhu crank on my gravelbike an never had an issue with it. My friend uses a quarq powermeter and needed to calibrate it a few time during the ride because the numbers were different to mine. And after the calibration of the quarq the numbers were better. So veryhappy with my power2max NGe
I have a classic, s type and NG and they are all reliable and consistent. I have put all three up against each other by comparing the power output of each unit using my Neo using speed as a constant. Each unit is within 1-2 watts of each other.
Thx for the installation overview, takes the edge of things. :-) Also: Their generous offer for desperate IQ2 backers makes them even more interesting.
That was an interesting marketing(?) tactic. I'd be more comfortable seeing them post that offer on their website or social channels. They swooped in on the IQ2 Backers Group and posted from a user account.... Hmm... Either way.... If people get a discount on a P2M, that's a good thing. What's the saying?.... "A power meter in the hand is worth a warehouse of IQ2 that'll never ship"
@@gplama P2M distribution is through regional representative companies, I wonder if it is one of those that is offering the deal. My local P2M dealer is great for that, sponsors local clubs and race teams, basically working overtime to make people happy.
I have the FSA Powerbox from Power2Max. Works great on my roadbike. I lost the battery cover one time while I was riding. I didn't notice it. I had to contact FSA and they sent me a couple of battery covers. Since then I didn't lose it again. I took the 50€ upgrade for left/right balance.
Thanks for the review. I have NGEco on my gravel-bike with Rival cranks and just ordered one for the Salsa fatbike with RF Next R cranks. Only complaint is the pricing: the Rival-version is 490€ but for some reason the MTB/RF -version is 630€. Add L/R-feature to that + P&P + a new 104BCD-chainring, you are nearing to 800€... not cheap I would say. Got the spare battery cover at the same time also. Because it is flimsy at the best. Haven't had any problems with my gravel but this can cahnge now with the fat bike, which will be ridden more in the woods.
I have 3 NGECO units on my bikes (Road, CX and MTB) and can't recommend them enough. The NGECO is reliable, competitively priced, great battery life, great customer service, locally supported and lots of compatibility options. I have some experience with the Power2Max customer service, both via Germany and the Australian distributor. I had some issues with the batteries in my Road and MTB units shortly after receiving them. I contacted Germany via the troubleshooting feature in the APP and they had a response back confirming the batteries were faulty in less than 24Hrs on both occasions. The Australian distributor offered to replace the batteries free of charge. I haven't had any issues since, I assume the units were shipped with a faulty batch of batteries.
@@Jeppelelle Still using it, never had any issues. The only drawback I have ran into is that there are no 104bcd offset chainrings like garbaruk does with their direct mount one by rings. So the frame max chainring is actually the max.
@@gplama No upgrades for me as i didn't see the value. BLE I think is a paid option and that's probably the only one i would pay for in the future. I bought this primarily as i had a "Smart" trainer, the Bkool Pro (0 stars review from me) that was wildly out in power numbers day to day but the resistance seemed to change OK for Zwift. I am doing a fair but of Zwift Racing so needed some consistency, all the other stuff is Ant+ so wasn't too worried about the BLE. Benefit was i had a power meter for outside too rather than spending up big on a new Smart trainer.
I have one of these on my Caad12. Power data was also a paid upgrade...that is, out of the box you only got cadence. In terms of the accuracy, theoretically they are all 1%, every NG gets tested for accuracy whereas every 1 in 10 NG eco is tested and the other 9 are calibrated from that. Paying for the added accuracy I think is a bit of a cash grab. The app for firmware updates and purchasing is absolutely horrible, one of the worst apps I've used. In saying all of this, I am happy with it. Once I got over the initial shock of paying extra dollars to get the power data and the fact that I rarely need to use the app, it is solid. Have it connected to a Garmin Edge 530 and Zwift and have never had an issue with it.
That would be an interesting debate and would love Shane to weigh in on that one. P2M NG/NG Eco just work (as they should) but I feel that people talk about the Quarq with more excitement
I have had this unit now for about a year and so far only two brief drop outs, otherwise it just works and I never have to double guess it’s accuracy. Have a look at GCNs’ visit to the factory.
I own two of these, CX and road bike. Awesome, zero problems and match my OG Neo perfectly. Only complaint is they should fix the app it must have been built 10 years ago, very glitchy.
I've been using one for almost 3 years now and when I first got it I thought exactly the same think, but to this day I've had no problems with tha battery cap. On the other hand it does not notify me when it's running out of battery and i've had a few dropouts issues. Anyways, I own a 4iiii left crank too and in my opinion the power2max is waaay better, you can tell it gives more consistent and stable data.
Thanks Bicycle Jesus! "Firmware update NOT done" - got some D-fly flashbacks there! Fortunately Power2Max did a better job than Shimano ;). I had been looking at the NGeco myself after my Stages Gen 2 drowned, but then made some other friends. I'll definitely have another look at them in the future though!
It was truely DFU'ed when the IOS app crashed out. Thankfully the app was able to gracefully recover, that's good programming! Looks like I'm not alone on this one searching the ww forums.....
@@gplama This is programming done right. Failed firmware update should never brick the device, it's unacceptable. I had few failed fw updates on Quarq Dzero and it always recovered from it nicely by itself (after some LED blinking festival).
@@gplama Was there another dialog box before the termination? The very first update I've had to do, it told me to disconnect bluetooth and reconnect in order to continue with the update. Without doing that, I would see a similar crash.
Sounds like a slightly more expensive alternative to the Quarq power meter (which is what I have and one of the reasons I went for a SRAM group). Like some others in the comment section, I don't think that the system of disabling features through software has appeal, but if it just works then that also deserves credit.
Another helpful video thanks! Just wondering do you have a timeframe for your part 3 of the review of the Stage SB20? Ray did a good job but would love to see your view on it too!
I have recently written off a MTB version of the NGeco as a result of a dropped chain during a sprint. Ripped a chunk of the plastic out (directly under the stickers). Would recommend a chainguide for mtb users.
I'll be the fly in the ointment when it comes to aftermarket support from the Australian distributor and P2M HQ - VCAT (local consumer affairs board) was required for a resolution. Messy, I felt like a Karen and really not at the level of support previously experienced - although I should add with a different Aussie distributor. At one stage I had three of these units across my bikes and one on my partners bike. Recommended them to many and resulted in many more of their units on friends bikes. Accurate (my testing echoed all that Lama has found) and (for the most part) just 'worked'. All bar one have been terrific and easily survived overseas trips, racing through Belgium and many indoor training sessions. Funnily it was my newest unit that developed a problem and created the aforementioned situation wherein the unit was returned. Of course this could happen with any brand and overall it's certainly still fair to say P2M make a great product. I would not have purchased as many as I had if they didn't. It is why I'm reticent to share this. Only my aftersales experience was so poor it bears worth mentioning. Especially as it was both the local distributor and P2M in Germany. Hopefully though most people have the experience I have with my older units, being that they just work. No muss, no fuss (so you'll never need aftermarket support).
This NGEco is much more accurate than TypeS (especially for the temperature chan ges), i had 4 TypeS, made tons of test 3-4 years ago with Neo and after the NG was released i swapped all my TypeSs for NGs (not Ecos).
Thanx for the overdue review ;-) One question about the install: In your time lapse video it seems like you did not have to re-adjust the front derailleure at all- so chainline came out exactly as with the stock shimano cranks? I have an NGeco and while it works 100% great and reliable, the Rotor cranks not so much: Even without any spacers on the NDS the chainline is still a bit wider than 43.5mm and also the crank arms are not 100% centered. Also not a fan of the preload ring on the Rotors: really hard to adjust... because there is no knurling/grip on the opposing side of the pinch screw, the only place to grip the ring is on the pinch screw part, which compresses the ring while turning. Rotors 30mm Ring seems like a more sensible design, but it's probably incompatible. If someone knows a viable replacement part for the preload ring- I'm interested ;-)
@@gplama definitely a great power meter, had one on the specialized, and it out lasted the bike (12months, user error on the bike) Now just sitting on the bench gathering dust :( It was just a power meter that just worked. Though other Aussie distributor was a little hard to deal with. Had to speak to head office to get a response :(
The chainline for the GRX compatible cranks is incorrect. They are not 2.5mm outboard like the stock GRX Cranks. This caused rubbing on the big ring while in the little ring and the 11/12 cogs. Support stated that I would just have to deal with it as is. I am going through the return process, as they are unwilling to help. Pretty disappointed, as the power comparisons that I ran were less than 2% when compared to a set of Assioma Duos.
@@gplama i have 3 :) (i was one of the first customer in 2017 for my 1st NG) that is the most accurate and precise pm in the market imho now , maybe the InfoCrank has the same top measurements but that is not so popular in amateur cycling (but the UCI HQ is using that and the British Cycling Fed too as a reference powermeter) . That up and down power fluctuation what You noticed was it with Edge 830? Because that is a 830 bug, i noticed too with a few times and on my Garmin Fenix3 the power values were spot on always in the same time.
@@andraslukoviczki519 The P2M NGeco was recorded with the Elemnt ROAM on that ride (I put the head unit name/type in the filename so I can quickly reference it).
@@gplama can i access somehow to these dcanalizer comparison links with NGEco ? I'm data-geek :) Hmm, interest than the Roam has bug too :D via ANT+ or via BT? (I'm using it only via ANT+ , the BT part is turned off in NG :))
Anybody know if the NGEco would be appropriate if I want dual side measurement on my cannondale Supersix 2021? I see they have a Cannondale model but just want to make sure. Would this be better than getting power pedals?
This is one of the power meters I've been looking at. The problem I have is I want to put it on eewings cranks for twelve speed campag? The eewings uses sram three bolt system to attach the spider and there doesn't seem to be chainrings that are officially compatible.
This was the 2% unit. I believe they all roll off the same production line but the 1% ones are guaranteed to go through the calibration verification process where as they only select a few of the 2% ones to test.
I've have a p2m ng eco +-2% from 3 years ago, ordered a new one with +-1% 4S version. Tacx neo @200W , NG eco old 202.66 , NG eco new calibrated 202.73 on steady state 4 mins intervals. Practically the two p2m were within the ballpark of 0.5W of each other and they were 1-1.5% (that 0.5% was mostly my pedalling inefficiency) with the neo 2T. No professional lab env, just changing bikes mid ride, doing the same intervals, calibrating at the same time of each ride.
I am not sure what you mean by a crank arm (single sided?) power meter being more accurate? They measure only one leg where one based on the spindle or spider measures both. My bikes have SRM, the NGEco and a 4iii . I gotta say they are all working well for me so far but I would probably buy another NGEco for the MTB should I pry myself away from my gravel ride. I appreciate your content. Thank you very much for putting it out!
To clarify: A true DUAL sided power sensor configuration is more accurate at measuring L/R balance. This wasn't a reference to a single sided power meter, or power measurement.
Finding a 40nm spec wrench is going to cost $. I snugged the crank down to my best estimate and it was fine. Chainring bolts on the other hand should be installed as per spec.
As long as you are creating enough force for the pedal to detect, they can figure out cadence. For nearly every reasonable use case...it works great. Only time I see it not work is when I'm spinning going down hills but not spinning fast enough to actually put power into the drive train.
I am considering a new NGeco vs. a used Stages LR for my new bike. I don't really care for the LR-Balance, but want a new chainset anyway, cause the bike came with a different crank length then I'm used to. What would be the better powermeter for my case? Used Stages is around a hundred euros cheaper.
Hi, i ve been thinking to get this power meter or the Favero assioma duo, i ve heard really good reviews on both! Any comments or suggestions would apreciate it !! tks
I switched from Favero UNO to Power2Max because I prefer SPD SL Cleats and because of a slight imbalance I have in my left leg- both were solved, super happy. But you can’t really go wrong with either
I purchased a Cannondale System Six hi-mod which came with the NGeco. I haven’t paid to activate it yet but was told the cadence should work anyway. I synced it with my wahoo roam and the sensor registered as power on the wahoo but the rpm/cadence reads N/A. Any ideas as to how to get the cadence to work?
Thank you, Shane. I tried contact their support but the folks in Canada weren’t able to figure it out. They recommended I contact the engineers in Germany. I thought you might know if the cadence worked without paying to have the Power2max turned on. If not, I will give their support team one more try.
Looks a good option, once I can afford one, easier to find a spider based PM than reasonably prices 165mm cranks based pm's. Is there a model for bbright and shimano rings + cranks?
Hey Shane, It's been a year since this video was uploaded, so I'm keeping my fingers and toes crossed to get an answer. But I was wondering if you know anything regarding the Power2Max GranFondo Set? How does the cranks compare with the Rotor Aldhu? Thanks!
Like a lot of things to do with technology and little job becomes a big job. It won't work on my iPhone so I will use an android phone. What if you haven't got an android phone would you have to go out and buy one?
It's only for the firmware update process. The app looks like it's from 2018 and needs to update to support IOS14 maybe? Nothing to hang them on. The config works perfect with IOS and current app.
Assioma on my road bike, P2M NG on my CX bike. Even if Favero eventually comes out with an SPD version, having several hundred dollars/euros wrapped up in something that takes as much abuse as CX pedals just doesn't work for me. Plus I'm not giving up my Time ATACs for anything!
I am looking at upgrading my Garmin Vector 2s. Was thinking of staying with Garmin and getting the 3s. Any idea how Garmin would compare to your Assioma? Thanks.
I have a 2020 Fuji Sportif 2.1, Shimano Sora components. I have been wanting a power meter, and plan to eventually upgrade my bike. Would this be able to fit on my bike? A lot of crank based don't fit on mine.
yes, just You need to buy it with crank (and need the 5bolts version /if You have 5bolts version chainrings now) with 110 or 130bcd, depending on your actual crankset and chainring setup, and You can put the old chainrings to this 5bolts version NGEco), this is the cheapest version with their own 24mm crank: www.power2max.com/en/product/ngeco-road-power2max-granfondo-set/
if You have this bike with this Shimano crank: www.cycletec.de/images/product_images/original_images/sportif2.1_801.jpg , than You need the 110-4S version from the mentioned NGEco with that "GF" crank.
That's an additional purchase/feature for the NG Eco. It's there in with the NG. I wouldn't rely on it though as it doesn't have gauges on left/right to give true L/R balance.
Can someone answer this: I have the NGeco on my Cannondale. Can I easily switch chain rings back and forth from mid compact to compact without affecting the power meter? Thanks!
Ok, replying to my own question: I followed Shane's advice and reached out to Power 2max about changing chainrings back and forth. They said that's fine, no issues with the power meter doing this.
@@gplama Thanks.. I'm going through their site, I can't seem to find it. I added it to cart and everything, but no upgrade option. I definitely prefer the battery to the rechargeable on the NG.
@@gplama I didn't update this, but it's for Europe only. The US site doesn't offer this, and it's not available unless I order from Europe. I did ask them to offer it, and they said they will relay that to HQ that there is interest in the US. Too late for me though, I ordered my PM with the normal +/1 2%.
Shane, a tad off topic. Some of us out here are having issue with the Direto XR in erg mode, can you let me know what smoothing setting and what wheel size you have plumbed into the direto xr that you tested this with. At 13.00 your power trace is totally flat for both XR and the Ngeco. We cant get close to that. Factory defaults are Smoothing 2 wheel size 2070 but for some apps it requires 171 for wheel size.. ... timely review.... I need a new power meter!! ( was that done in zwift?)
Smoothing 2 and default wheel size 2070 in the app. This was connecting to Zwift on Windows via BLE. Not sure if this was with the latest Zwift release, the dates will be on screen to line up.
@@1carusjohn32 for smooth power chart You need very steady cadence, if You always "chase" the target and your cadence is moving up and down (accelerating and after slowing down) the power chart will have bigger deviations. So always the smooth pedaling and steady cadence will result flat power chart (in ERG mode)
@@andraslukoviczki519 hmm controlled erg mode should level the watts for a reasonable consistent effort and cadence ... else you could just put a number on the screen and hit the watts yourself by holding a fixed speed and cadence fro the required wattage.
@@1carusjohn32 all the trainers are trying to keep the power on target level but they cant handle the unsmooth and unsteady pedaling, the beginner users on Neo are pedaling with +-30watts (sometimes even more) deviations in ERG mode at 200watts, the advanceds are with 2-3watts (but probably they started with 20-30w too just with lots of practice they could reach this best/lowest deviation) , just need to concentrate enough and need to "learn" the behaviour of the given trainer. Shane is an advanced rider who spent enough time on different trainers.
@@gplama thanks so much. I really appreciate all your reviews!!! Have you had time to sort out the issue you were having with the Rotor inSpider power meter? Seems very similar to the Power2Max.
Hey Shane and everyone have you ever had weird power spikes out of no where. It happens to me 3 times a ride at least. I have the ng eco, a quarq dfour, and 4i duel sided. Also have you ever noticed 4i duel sided under reads as high intensities.
Check the FIT file and look at the cadence data at the point the power spikes. That's usually an indication something funky is happening with cadence. (Also check you're on the latest firmware!). RE: The 4iiii. It depends on what crank. The dual sided Shimano has issues with the crank design.
@@gplama ya I have the shimano 4i. I’m just so tired of power meters that don’t work. The 4i was saying I 46/54 in balance between my legs. I also had PowerTap p2 pedals and I’ve never been any more then a 48/52. Also in your experience does the quarq and ng eco match up pretty well since there both spider based power meters
If you want to read up on the Shimano issue: gplama.com/2019/06/29/shimano-crankset-power-meters/ I'm happy with the power data from the Quarq units I have here and the P2M NGeco.
@@gplama thanks for sharing the link. I have more faith that my ng eco is right now. I did an FTP test on the 4iiii when I first got them. It made me think that all my training didn’t do anything Over the course of 5 weeks. Well based on the charts it says it reads 8.84 % lower. Which means my FTP is 8.84% higher
The CR2450 has almost 3x more capacity than a CR2032. And just look what happen if a powermeter needs more than 1 battery , Vector3 and its stability issue.... You should change battery much more often with 1pc CR2032 and if the temperature drop suddenly the small capacity goes down to 0 very quickly and the powermeter's operation is stopping. Usually 1 CR2450(or 2450N) is enough for 10k km so an average cyclist needs to change it yearly...
Does anyone experience very jagged data from their p2max? Im comparison to my trainer and other power sources, averages are very close so I’m very happy with my p2max ng eco however, for example, at a 220 watt erg mode on mu trainer, p2m will read up and down between 215 and 225 watts constantly. This wouldn’t be an issue except when I use p2max controlling the erg mode, this means power constantly changing up and down from harder than it should feel to too easy and back every 5-10 seconds. Pretty frustrating if you wanna do a nice consistent effort.
That's normal. What you're comparing against is likely power smoothing on a Wahoo trainer? (as at a guess). See this video for more information: ruclips.net/video/7L7hfT0I7E0/видео.html
@@gplama It seems a little more exaggerated than that I'm afraid. The only time I experienced this much up and down was 4iiii left only which also reported great averages but I couldn't use it as a power source on erg mode cause the trainer would just keep adjusting hard / easy / hard / easy and drive me crazy. I actually remember your review of 4iiii revealed the same thing!
Been my first powermeter for 4 months now. Works great and data seems to be roughly consistent with the two trainers that i had. Battery life seems great too!
I have one of these since May 2018, loving it and zero issues with the battery cover 👌🏻
The P2Max was one of the very few options for my fat bike. The extra big battery is a bonus for me in that my winter races are very cold. Last year during my A-race (Alaska Frosty Bottom) the temperature reached -15F/-26C when my Wahoo Bolt computer died (even with an aux battery pack supplying power), but my P2Max kept pumping out data right to the end. I agree the rubber battery cover is a weak bit. It feels like it could come off easily, but in three years of use, it has never come loose or fallen off.
I have this power meter since 2 years, happy to see this test!
After using my FSA Powerbox Carbon on my triathlon bike for 3 years. All I do is change out the battery the night before a race, verify its connected to my headunit pre-race, and have fun. It’s been absolutely 0 fuss or problems, and it just simply works. I love it, I’ll get another one for my next TT build honestly.
I’ve been using an Eco since shortly after they came out. Quite literally never had a single issue with it.
Thanks Shane for your work.
I've been using it since 6 months on my MTB (scott spark with sram crankset) without any issues with data or battery cover; I definitely reccomend it!
Always thought the P2M was a good pm, great to have that confirmed! Battery cover - my friend has ridden two full CX seasons here in the UK (so aweful conditions...) and myself one season using the P2M ngeco. Not one single issue with the cover and they got a lot of abuse in that time!
I am a Shimano Ultegra 6800 user who has have recently bought this ngeco power meter and rotor aldhu 24 crank combination. This review of Shanes was a big factor in my decision.
I am extremely happy with the accuracy and quality of the product. I have specific fit issues which prevent me using Faveros. I still wanted a power meter that allowed me to keep using my current Shimano bottom bracket and current Shimano chainrings. Also, it had to be ACCURATE.
Prior to the power2max I been using a 4iiii left-crank-leg PM with a poor quality strain gauge that broke after 18 months (as did several of my friends), then a Pioneer left-crank-leg power PM which either under or over measured power, thus inaccurate. Both were measured against a Tacx Neo first generation.
I'm happy to say that the Power2max is accurate. It perfectly and repeatedly matches the Neo in both power and cadence. Its very easy to install and simple to use. I'm also happy that if I ever upgrade to 12 speed Shimano, I can continue to use this same power meter, as it fits all 11 and 12 speed Shimano chainrings. Somehow Shimano can't even offer this level of compatibility with their own cranks.
A tip for anyone considering this product and wanting to save money. There is a lower cost crank arm option called "Rotor Vegast 24" which is only 60 grams heavier. Power2max also rebrand Vegast 24 arms with their own logo and sell as a combination with the ngeco spider.
Thanks for the video. Seems to be a great powermeter. What holds me back is the weight and having to buy a non standard crankset.
Thanks Shane...am considering one of these for my next build as I am also considering Campy Super Record 12S and I can buy as a complete Spider and Crank
it just works :) I have an NG for over a year now.
I use the NGEco on 2 Bikes. One with the FSA Powerbox Alloy (as OEM Integration) and the new Spider for Shimano XT (MTB) and both work excellent. Best Powermeter so far. Switched from Assioma Duo because I changed my Road for a Gravel bike and and the assioms wont run with Standard SPD.

Except the L/R balance is nothing of the sort. It doesn't measure L/R balance at all, and they shouldn't be offering a paid 'upgrade' to 'measure' it.
@@pmcmpc idk anybody more than 2% off with left right. It's a mostly pointless feature
I use this powermeter with the Aldhu crank on my gravelbike an never had an issue with it. My friend uses a quarq powermeter and needed to calibrate it a few time during the ride because the numbers were different to mine. And after the calibration of the quarq the numbers were better. So veryhappy with my power2max NGe
Great review, to the point. Thank you. Considering this power meter for a new Shimano Deore XT 1x12 crank.
I have P2M NG eco and S-type, they are both reliable and accurate, would now never consider anything else and always happy to recommend to mates.
I have a classic, s type and NG and they are all reliable and consistent. I have put all three up against each other by comparing the power output of each unit using my Neo using speed as a constant. Each unit is within 1-2 watts of each other.
GP-Lama Wicked Pissah Cool video! Looks like a great Power Meter
Thx for the installation overview, takes the edge of things. :-)
Also: Their generous offer for desperate IQ2 backers makes them even more interesting.
That was an interesting marketing(?) tactic. I'd be more comfortable seeing them post that offer on their website or social channels. They swooped in on the IQ2 Backers Group and posted from a user account.... Hmm... Either way.... If people get a discount on a P2M, that's a good thing. What's the saying?.... "A power meter in the hand is worth a warehouse of IQ2 that'll never ship"
@@gplama P2M distribution is through regional representative companies, I wonder if it is one of those that is offering the deal. My local P2M dealer is great for that, sponsors local clubs and race teams, basically working overtime to make people happy.

I have the FSA Powerbox from Power2Max. Works great on my roadbike. I lost the battery cover one time while I was riding. I didn't notice it. I had to contact FSA and they sent me a couple of battery covers. Since then I didn't lose it again. I took the 50€ upgrade for left/right balance.
That is not nice. They charge for something that should be there 😂
Thanks for the review. I have NGEco on my gravel-bike with Rival cranks and just ordered one for the Salsa fatbike with RF Next R cranks. Only complaint is the pricing: the Rival-version is 490€ but for some reason the MTB/RF -version is 630€. Add L/R-feature to that + P&P + a new 104BCD-chainring, you are nearing to 800€... not cheap I would say.
Got the spare battery cover at the same time also. Because it is flimsy at the best. Haven't had any problems with my gravel but this can cahnge now with the fat bike, which will be ridden more in the woods.
I have 3 NGECO units on my bikes (Road, CX and MTB) and can't recommend them enough. The NGECO is reliable, competitively priced, great battery life, great customer service, locally supported and lots of compatibility options.
I have some experience with the Power2Max customer service, both via Germany and the Australian distributor.
I had some issues with the batteries in my Road and MTB units shortly after receiving them. I contacted Germany via the troubleshooting feature in the APP and they had a response back confirming the batteries were faulty in less than 24Hrs on both occasions. The Australian distributor offered to replace the batteries free of charge. I haven't had any issues since, I assume the units were shipped with a faulty batch of batteries.
oh yeah, long time waiting for this :D
I have one of these, it’s brilliant.
I'll be picking one of these up next month on pay day....
I have been using this unit on my Mountainbike for almost a year now, never had any issues with the battery cover or with the data.
Are you still riding it? I am thinking about getting the ngeco for my MTB, so, any issues that have been creeping up for you?
@@Jeppelelle Still using it, never had any issues. The only drawback I have ran into is that there are no 104bcd offset chainrings like garbaruk does with their direct mount one by rings. So the frame max chainring is actually the max.
Did I hear right at about 15:22. The power 2 max 'spiderbait' power meter. Love a good pop culture reference!!
I run the FSA Powerbox which is a NG Eco in a different wrapper. Great to see that it passes, makes me feel better that my power numbers are legit...
I tried to get a hold of a PowerBox a few months back, no luck. Did you choose to buy any of the upgrades on that unit? Was BLE a paid extra?
@@gplama No upgrades for me as i didn't see the value. BLE I think is a paid option and that's probably the only one i would pay for in the future. I bought this primarily as i had a "Smart" trainer, the Bkool Pro (0 stars review from me) that was wildly out in power numbers day to day but the resistance seemed to change OK for Zwift. I am doing a fair but of Zwift Racing so needed some consistency, all the other stuff is Ant+ so wasn't too worried about the BLE. Benefit was i had a power meter for outside too rather than spending up big on a new Smart trainer.
About time Shane u tested p2m😁
Been running one of these for almost 1.5 years and it’s been very reliable. Great value too.
I have one of these on my Caad12. Power data was also a paid upgrade...that is, out of the box you only got cadence.
In terms of the accuracy, theoretically they are all 1%, every NG gets tested for accuracy whereas every 1 in 10 NG eco is tested and the other 9 are calibrated from that. Paying for the added accuracy I think is a bit of a cash grab.
The app for firmware updates and purchasing is absolutely horrible, one of the worst apps I've used.
In saying all of this, I am happy with it. Once I got over the initial shock of paying extra dollars to get the power data and the fact that I rarely need to use the app, it is solid. Have it connected to a Garmin Edge 530 and Zwift and have never had an issue with it.
I have one myself and that battery compartment is quite clunky- but it works!
Awesome video. I’ve been debating P2M or Quarq for my next PM
That would be an interesting debate and would love Shane to weigh in on that one.
P2M NG/NG Eco just work (as they should) but I feel that people talk about the Quarq with more excitement
I have had this unit now for about a year and so far only two brief drop outs, otherwise it just works and I never have to double guess it’s accuracy. Have a look at GCNs’ visit to the factory.
I own two of these, CX and road bike. Awesome, zero problems and match my OG Neo perfectly. Only complaint is they should fix the app it must have been built 10 years ago, very glitchy.
I've been using one for almost 3 years now and when I first got it I thought exactly the same think, but to this day I've had no problems with tha battery cap.
On the other hand it does not notify me when it's running out of battery and i've had a few dropouts issues.
Anyways, I own a 4iiii left crank too and in my opinion the power2max is waaay better, you can tell it gives more consistent and stable data.
Thanks Bicycle Jesus! "Firmware update NOT done" - got some D-fly flashbacks there! Fortunately Power2Max did a better job than Shimano ;). I had been looking at the NGeco myself after my Stages Gen 2 drowned, but then made some other friends. I'll definitely have another look at them in the future though!
It was truely DFU'ed when the IOS app crashed out. Thankfully the app was able to gracefully recover, that's good programming! Looks like I'm not alone on this one searching the ww forums.....
@@gplama This is programming done right. Failed firmware update should never brick the device, it's unacceptable. I had few failed fw updates on Quarq Dzero and it always recovered from it nicely by itself (after some LED blinking festival).
@@gplama Was there another dialog box before the termination? The very first update I've had to do, it told me to disconnect bluetooth and reconnect in order to continue with the update. Without doing that, I would see a similar crash.
@@GoonieGooGoo910 No dialogue. The app crashed leaving the unit in DFU mode.
Sounds like a slightly more expensive alternative to the Quarq power meter (which is what I have and one of the reasons I went for a SRAM group). Like some others in the comment section, I don't think that the system of disabling features through software has appeal, but if it just works then that also deserves credit.
did this just happen?!?! the Lama super happy with an item? I am out the door to buy it!
It’s a rare occurrence. 🤣
I have one on my Canyon Endurace. Works great paired with my Wahoo Roam, Zwift, and TrainerRoad. The app is a bit finicky.
Power2max - just works.
Can confirm! :)
Another helpful video thanks! Just wondering do you have a timeframe for your part 3 of the review of the Stage SB20? Ray did a good job but would love to see your view on it too!
I have recently written off a MTB version of the NGeco as a result of a dropped chain during a sprint. Ripped a chunk of the plastic out (directly under the stickers). Would recommend a chainguide for mtb users.
I'll be the fly in the ointment when it comes to aftermarket support from the Australian distributor and P2M HQ - VCAT (local consumer affairs board) was required for a resolution. Messy, I felt like a Karen and really not at the level of support previously experienced - although I should add with a different Aussie distributor. At one stage I had three of these units across my bikes and one on my partners bike. Recommended them to many and resulted in many more of their units on friends bikes. Accurate (my testing echoed all that Lama has found) and (for the most part) just 'worked'. All bar one have been terrific and easily survived overseas trips, racing through Belgium and many indoor training sessions. Funnily it was my newest unit that developed a problem and created the aforementioned situation wherein the unit was returned.
Of course this could happen with any brand and overall it's certainly still fair to say P2M make a great product. I would not have purchased as many as I had if they didn't. It is why I'm reticent to share this. Only my aftersales experience was so poor it bears worth mentioning. Especially as it was both the local distributor and P2M in Germany.
Hopefully though most people have the experience I have with my older units, being that they just work. No muss, no fuss (so you'll never need aftermarket support).
Agreed. The Aussie support is woeful/non-existent. Have always gone through the German support.
Great to see this mate - always said P2M was good, albeit the TypeS models I have. Great job.
This NGEco is much more accurate than TypeS (especially for the temperature chan
ges), i had 4 TypeS, made tons of test 3-4 years ago with Neo and after the NG was released i swapped all my TypeSs for NGs (not Ecos).
Awesome & Thanks :)
Thanx for the overdue review ;-)
One question about the install: In your time lapse video it seems like you did not have to re-adjust the front derailleure at all- so chainline came out exactly as with the stock shimano cranks?
I have an NGeco and while it works 100% great and reliable, the Rotor cranks not so much: Even without any spacers on the NDS the chainline is still a bit wider than 43.5mm and also the crank arms are not 100% centered. Also not a fan of the preload ring on the Rotors: really hard to adjust... because there is no knurling/grip on the opposing side of the pinch screw, the only place to grip the ring is on the pinch screw part, which compresses the ring while turning. Rotors 30mm Ring seems like a more sensible design, but it's probably incompatible. If someone knows a viable replacement part for the preload ring- I'm interested ;-)
That's one PHAT battery.
Long time coming... ;p
Three years.... I finally got there! :)
@@gplama definitely a great power meter, had one on the specialized, and it out lasted the bike (12months, user error on the bike)
Now just sitting on the bench gathering dust :(
It was just a power meter that just worked.
Though other Aussie distributor was a little hard to deal with. Had to speak to head office to get a response :(
Are your findings based on the standard 2% accuracy option or the upgraded 1% version ? Thank you very much for your videos
2%
The chainline for the GRX compatible cranks is incorrect. They are not 2.5mm outboard like the stock GRX Cranks. This caused rubbing on the big ring while in the little ring and the 11/12 cogs. Support stated that I would just have to deal with it as is. I am going through the return process, as they are unwilling to help. Pretty disappointed, as the power comparisons that I ran were less than 2% when compared to a set of Assioma Duos.
Is the tested unit in the video accurate to 1 or 2%? And what is the opinion about paying extra for more accuracy?
Thx Shane, finally You could test it! :) and If You could test the NG model You wouldnt find any "downsides" ;)

HI, dose NG support Garmin cycling dynamics data?
This is one of the power meters I've been looking at. The problem I have is I want to put it on eewings cranks for twelve speed campag? The eewings uses sram three bolt system to attach the spider and there doesn't seem to be chainrings that are officially compatible.
The spider will fit take the place of the 3 bolt direct mount, and then you'll use a 4 bolt chain ring attached to the ng eco spider.
Hey Shane, Awesome review mate. Just wondering if you were using the 2% power accuracy unit or the upgraded 1% accuracy for this review?
This was the 2% unit. I believe they all roll off the same production line but the 1% ones are guaranteed to go through the calibration verification process where as they only select a few of the 2% ones to test.
Cheers mate. Keen to get one of these units. 😁
I've have a p2m ng eco +-2% from 3 years ago, ordered a new one with +-1% 4S version. Tacx neo @200W , NG eco old 202.66 , NG eco new calibrated 202.73 on steady state 4 mins intervals. Practically the two p2m were within the ballpark of 0.5W of each other and they were 1-1.5% (that 0.5% was mostly my pedalling inefficiency) with the neo 2T. No professional lab env, just changing bikes mid ride, doing the same intervals, calibrating at the same time of each ride.
I am not sure what you mean by a crank arm (single sided?) power meter being more accurate? They measure only one leg where one based on the spindle or spider measures both.
My bikes have SRM, the NGEco and a 4iii . I gotta say they are all working well for me so far but I would probably buy another NGEco for the MTB should I pry myself away from my gravel ride.
I appreciate your content. Thank you very much for putting it out!
To clarify: A true DUAL sided power sensor configuration is more accurate at measuring L/R balance. This wasn't a reference to a single sided power meter, or power measurement.
Can you feel the 40nm on the crank installation? I'm wondering should I buy a torque wrench that supports 40nm range.
Finding a 40nm spec wrench is going to cost $. I snugged the crank down to my best estimate and it was fine. Chainring bolts on the other hand should be installed as per spec.
Hi Folks! Any fresh - as of 2023 - concensus on NG vs NG ECO? Worth to pay extra? 🙂
Want to run 2x oval setup if that matters, cx sport bike.
Hi GPLlama, wonder if have to have cadence sensor if you have a power meter? Love your content 👍
No need. Power meters will give you cadence too.
As long as you are creating enough force for the pedal to detect, they can figure out cadence. For nearly every reasonable use case...it works great. Only time I see it not work is when I'm spinning going down hills but not spinning fast enough to actually put power into the drive train.
I have a gravel bike with GRX and am confused on what will work on the bike. Do you have a suggestion?
I'm not across the specifics of the GRX cranks. I know INPeak and Stages are offering GRX crank options for their meters.
Did you use any grease or loctite between the powermeter spider and the spindle?
No.
Hey Shane,
In the test you made, was the P2M accuracy upgraded?
Thanks for the nice test.
No.
Super, many thanks for the reply.
Do you think it is necessary to upgrade if you are a regular exerciser
I am considering a new NGeco vs. a used Stages LR for my new bike. I don't really care for the LR-Balance, but want a new chainset anyway, cause the bike came with a different crank length then I'm used to.
What would be the better powermeter for my case? Used Stages is around a hundred euros cheaper.
P2M hands down.
@@gplama thank you for that quick response! P2M it is then.
Hi, i ve been thinking to get this power meter or the Favero assioma duo, i ve heard really good reviews on both!
Any comments or suggestions would apreciate it !! tks
Not much I can add to be honest. It's entirely up to you what to go with.
Given the very similar price point, is Rotor better or worse then Power2Max?? I appears you had to replace the spindle and crank arms.
Avoid the Rotor pmeters if You dont wanna lose your hairs! 😃
Only question left: should i go with Favero or P2Max? Great video!
I switched from Favero UNO to Power2Max because I prefer SPD SL Cleats and because of a slight imbalance I have in my left leg- both were solved, super happy. But you can’t really go wrong with either
@@illuminatustm thanks for your input!
Is there any alternative way to update firmware for those without an Android device?
No, only with Android or with IOS app, cant update it via cycling head unit or with computer.
I don't have the chainring bolts and shimano don't seem to sell them, is there an alternative?
One for your lbs
I purchased a Cannondale System Six hi-mod which came with the NGeco. I haven’t paid to activate it yet but was told the cadence should work anyway. I synced it with my wahoo roam and the sensor registered as power on the wahoo but the rpm/cadence reads N/A. Any ideas as to how to get the cadence to work?
One for Power2Max Support
Thank you, Shane. I tried contact their support but the folks in Canada weren’t able to figure it out. They recommended I contact the engineers in Germany. I thought you might know if the cadence worked without paying to have the Power2max turned on. If not, I will give their support team one more try.
Looks a good option, once I can afford one, easier to find a spider based PM than reasonably prices 165mm cranks based pm's. Is there a model for bbright and shimano rings + cranks?
Not sure. That's one for Power2Max Support. They should have an answer on that right away.
@@gplama cheers.
Is it me or does Assioma always read abit high compares to other powermeters?
Not my experience across four sets of them and 100s of comparative tests.

Is the power2max better than a quarq, or the are slightly the same?
They're very similar.
Will we ever see decent SPD based power meter pedals?

Hey Shane,
It's been a year since this video was uploaded, so I'm keeping my fingers and toes crossed to get an answer. But I was wondering if you know anything regarding the Power2Max GranFondo Set? How does the cranks compare with the Rotor Aldhu?
Thanks!
I’m not familiar with that sorry.
@@gplama thanks for the reply!
Like a lot of things to do with technology and little job becomes a big job. It won't work on my iPhone so I will use an android phone. What if you haven't got an android phone would you have to go out and buy one?
It's only for the firmware update process. The app looks like it's from 2018 and needs to update to support IOS14 maybe? Nothing to hang them on. The config works perfect with IOS and current app.
Does anybody have any experience installing this power meter on a Shimano DXR crankset (used for single speed application)?
Since I bought Assioma DUO I am not sure why any other power meter exists ;-)
Assioma on my road bike, P2M NG on my CX bike. Even if Favero eventually comes out with an SPD version, having several hundred dollars/euros wrapped up in something that takes as much abuse as CX pedals just doesn't work for me. Plus I'm not giving up my Time ATACs for anything!
I am looking at upgrading my Garmin Vector 2s. Was thinking of staying with Garmin and getting the 3s. Any idea how Garmin would compare to your Assioma? Thanks.

iirc, yes, there was two.

yes, just You need to buy it with crank (and need the 5bolts version /if You have 5bolts version chainrings now) with 110 or 130bcd, depending on your actual crankset and chainring setup, and You can put the old chainrings to this 5bolts version NGEco), this is the cheapest version with their own 24mm crank: www.power2max.com/en/product/ngeco-road-power2max-granfondo-set/
if You have this bike with this Shimano crank: www.cycletec.de/images/product_images/original_images/sportif2.1_801.jpg , than You need the 110-4S version from the mentioned NGEco with that "GF" crank.
@@andraslukoviczki519 yes that's my bike. awesome thank you!
Can you please tell if it shows L/R balance?
That's an additional purchase/feature for the NG Eco. It's there in with the NG. I wouldn't rely on it though as it doesn't have gauges on left/right to give true L/R balance.
Why a metal disc with some strain gauges is so expensive?
Because whenever someone tries to make a cheaper one, it’s usually pretty bad.
Can someone answer this: I have the NGeco on my Cannondale. Can I easily switch chain rings back and forth from mid compact to compact without affecting the power meter? Thanks!
Shouldn’t be a problem. Ping Power2max support for an offical answer on this though.

Shane, a tad off topic. Some of us out here are having issue with the Direto XR in erg mode, can you let me know what smoothing setting and what wheel size you have plumbed into the direto xr that you tested this with. At 13.00 your power trace is totally flat for both XR and the Ngeco. We cant get close to that. Factory defaults are Smoothing 2 wheel size 2070 but for some apps it requires 171 for wheel size.. ... timely review.... I need a new power meter!! ( was that done in zwift?)
Smoothing 2 and default wheel size 2070 in the app. This was connecting to Zwift on Windows via BLE. Not sure if this was with the latest Zwift release, the dates will be on screen to line up.
@@gplama well we certainly dont get that!!
@@1carusjohn32 for smooth power chart You need very steady cadence, if You always "chase" the target and your cadence is moving up and down (accelerating and after slowing down) the power chart will have bigger deviations.

@@andraslukoviczki519 hmm controlled erg mode should level the watts for a reasonable consistent effort and cadence ... else you could just put a number on the screen and hit the watts yourself by holding a fixed speed and cadence fro the required wattage.
@@1carusjohn32 all the trainers are trying to keep the power on target level but they cant handle the unsmooth and unsteady pedaling, the beginner users on Neo are pedaling with +-30watts (sometimes even more) deviations in ERG mode at 200watts, the advanceds are with 2-3watts (but probably they started with 20-30w too just with lots of practice they could reach this best/lowest deviation) , just need to concentrate enough and need to "learn" the behaviour of the given trainer.

Why use Rotor crank arms with the DuraAce chainrings? Will DuraAce crank arms not work? Can Power2Max work with Shimano 105?
Shimano crank arms are not compatible with this spider. The arms on those are the spider (integrated).

Hey Shane and everyone have you ever had weird power spikes out of no where. It happens to me 3 times a ride at least. I have the ng eco, a quarq dfour, and 4i duel sided. Also have you ever noticed 4i duel sided under reads as high intensities.
Check the FIT file and look at the cadence data at the point the power spikes. That's usually an indication something funky is happening with cadence. (Also check you're on the latest firmware!). RE: The 4iiii. It depends on what crank. The dual sided Shimano has issues with the crank design.
@@gplama ya I have the shimano 4i. I’m just so tired of power meters that don’t work. The 4i was saying I 46/54 in balance between my legs. I also had PowerTap p2 pedals and I’ve never been any more then a 48/52. Also in your experience does the quarq and ng eco match up pretty well since there both spider based power meters
If you want to read up on the Shimano issue: gplama.com/2019/06/29/shimano-crankset-power-meters/
I'm happy with the power data from the Quarq units I have here and the P2M NGeco.
@@gplama thanks for sharing the link. I have more faith that my ng eco is right now. I did an FTP test on the 4iiii when I first got them. It made me think that all my training didn’t do anything Over the course of 5 weeks. Well based on the charts it says it reads 8.84 % lower. Which means my FTP is 8.84% higher
Great power meter. Too bad I also have to buy new cranks.
Brilliant. A minor quibble, too bad it's not a 2032 battery. Those are far more common
The CR2450 has almost 3x more capacity than a CR2032. And just look what happen if a powermeter needs more than 1 battery , Vector3 and its stability issue.... You should change battery much more often with 1pc CR2032 and if the temperature drop suddenly the small capacity goes down to 0 very quickly and the powermeter's operation is stopping. Usually 1 CR2450(or 2450N) is enough for 10k km so an average cyclist needs to change it yearly...
@@andraslukoviczki519 Thats very good to know. I had no idea
What's a magpie worth in Watts?
Easy a 15% boost!
zero plastic package
Isn't it just a torque sensor???
Yes
Does anyone experience very jagged data from their p2max? Im comparison to my trainer and other power sources, averages are very close so I’m very happy with my p2max ng eco however, for example, at a 220 watt erg mode on mu trainer, p2m will read up and down between 215 and 225 watts constantly. This wouldn’t be an issue except when I use p2max controlling the erg mode, this means power constantly changing up and down from harder than it should feel to too easy and back every 5-10 seconds. Pretty frustrating if you wanna do a nice consistent effort.
That's normal. What you're comparing against is likely power smoothing on a Wahoo trainer? (as at a guess). See this video for more information: ruclips.net/video/7L7hfT0I7E0/видео.html
@@gplama It seems a little more exaggerated than that I'm afraid. The only time I experienced this much up and down was 4iiii left only which also reported great averages but I couldn't use it as a power source on erg mode cause the trainer would just keep adjusting hard / easy / hard / easy and drive me crazy. I actually remember your review of 4iiii revealed the same thing!
