power2max NGeco SRAM MTB Power Meter

The NGeco is the newest model in the power2max line-up. With features such as dual leg power measurement, ANT+/Bluetooth SMART compatibility and left/right power balance, the power2max NGeco SRAM MTB Power Meter comes fully-loaded. In addition, the NGeco is accurate to +/- 2.0% in all environmental conditions and is easy to use with features such as auto-zero and accelerometer-based cadence measurement. In fact, there is no other power meter that provides dual-leg power measurement plus these other features at only $590!


Key Product Details


This power2max fits SRAM direct mount 3-bolt cranksets. Regarding chainrings, it requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many SRAM MTB cranksets). If you don’t already have a 104 BCD 4-bolt chainring, we offer several to choose from. See Compatibility tab for more information.

Power Measurement:

The power2max power meter measures power at the spider and is therefore able to measure power from both legs.

Key Features:

Dual-leg power measurement, accurate to +/- 2.0%, 300-400 hours of battery life, CR2450 user-replaceable battery, left/right power balance with system upgrade, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration). See Specs tab for more information.

Advice From Our Staff:

This is probably our best-selling MTB power meter. SRAM 3-bolt MTB cranksets are very common and this is a great way to add power to them. It measures power from both legs, is accurate and reliable. We believe the price also represents a good value for what you get. We highly recommend power2max power meters and use them on many of our own bikes.


Options For This Power Meter

Chainline and BCD: This power meter is available in the following versions:

  • 1X Boost | 104 BCD
  • 1X Standard | 104 BCD

The 1X Boost configuration is recommended if your bike currently has a direct mount chainring with a 3 mm offset (which is what most bikes have). These bikes usually feature 52 mm chainlines and 148 mm rear hubs. Please note this Boost version can also fit Super Boost bikes where you are replacing a 3 mm direct mount chainring.

The 1X Standard configuration is used for bikes that have a direct mount chainring with a 6 mm offset (usually found on older bikes). These bikes usually feature 49 mm chainlines and 142 mm rear hubs.


Other Versions to Consider

Upgraded NG Version: While the NGeco you are viewing on this page is our go-to version for most cyclists, please note we also have the upgraded power2max NG SRAM MTB Power Meter. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics.


Crankset: The power2max NGeco SRAM MTB Power Meter fits SRAM direct mount 3-bolt cranksets. In order for this power meter to fit, you must ensure your SRAM uses this interface. Please see the image below.

SRAM 3-bolt Interface on MTB crankset

Chainrings: This power meter requires a 104 BCD 4-bolt MTB chainring (which is different than the direct mount chainrings found on many SRAM MTB cranksets). If you don't already have a 4-bolt chainring, we offer several to choose from.

The smallest chainring you can use on a power2max MTB power meter is a 30T round or 32T oval.

If you purchase a new chainring with your power meter, we will bolt it on to your power meter before shipping, which will make installation that much easier when you get it.

*Power Balance Upgrade

The power2max NGeco measures power from both legs right out of the box. However, with power balance, you are able to see how much power each leg is generating individually. If this information is important to you, you can choose to upgrade the power meter at any time. (Please note, you can also purchase the NG version of the power2max which comes with this feature unlocked, along with a rechargeable battery and a longer 5-year warranty.)

You can upgrade your NGeco using the power2max app once you receive the power meter. The cost to upgrade is 50 euros.

    Consistently reads low.

    After several months of use, I am confident that the power2max NGeco SRAM MTB Power Meter that I ordered back in Oct 2021 is inaccurate (reads low).

    I own several power meters, including a Wahoo KICKR, three Quarq DZERO power meters, and one other power2max NGeco on my gravel bike. Compared to all of my other power meters, my new power2max reads low for a given effort.

    My zero offset number consistently returns a value of -188 to -189 before each ride, and my firmware is up to date.

    My only option is to send the power meter to Canada for a test and hope they either replace it or recalibrate it.

      Hi Dave. Thanks for the review. We’re sorry to hear about any problems with your power2max. It’s strange because these are some of the best power meters on the market. They are wonderfully accurate, consistent and reliable. Have you tested the accuracy of your p2m with 2 or more power meters on the bike at once…as this is really the only way to know for sure? In any event, if there is anything we can do on our end to help, please let us know!

    Perfect alternative to the Quarq XX1 Eagle power meter. I have a SRAM GX groupset on my Santa Cruz and would have needed the full Quarq Eagle setup with new chain ring and crank arms. The Power2Max allowed me to save $410 by using my existing GX crank arms and only replacing the chain ring. Took about 5 minutes to install and works perfectly with my Garmin watch. Very happy with the purchase.

    • Power Meter City

      Thank you, David! We hope you will continue to enjoy your new power meter! If there is anything else we can do, please let us know!

    The staff at PMC was really helpful in giving me less expensive alternatives to the Quarq PM(which would have required me to buy a new 8-bolt XX1 crankset). After several very quick replies via email to my questions, I settled on their recommendation of the P2Max PM. It shipped the day I bought it(a Saturday, at that), and I received it in two days, from CA to VA! Super happy with their service, and so far I like the P2Max PM just as much as the Quarq I have on my road bike.

      Amazing! Thank you for this, Christopher! If there is anything else we can do, please let us know!

    I discovered power metrics during covid on my indoor bike (using the Wahoo SYSTM app) which fed my love for data. Now, after installing the PowerMax NGECO SRAM on my Stumpy, I get to enjoy the data _and_ shred Two Burmas 🙂
    I have the SRAM Descendant 7k crankset (nothing special) with DUB BSA 73mm BB (Boost chainline); installing the PowerMax spider was straightforward with the right tools. Shown in the photo is the Wolf Tooth 1x 30T 104BCD chainring which _does_ fit the PowerMax; raised standoffs at the bolts ensure chain clearance from the spider.

    The PowerMax needs the mobile app but registration in the mobile app was impossible; registering on the website was the only way, and then login the mobile app.

    I paired this power meter with Garmin 1030 plus. 2 things of note:
    1) when scanning for sensors with with Garmin, wait for the ANT+ sensor (distinguishable by the numeric identifier, BLE sensors have text description) of the power meter.
    2) the cadence data is in the power meter sensor stream; just add the cadence field to your power/flow/grit/distance/speed screen (there isn’t a separate cadence sensor, in case you’re waiting for one)

    Shoutout to the folks at Power Meter City who called me minutes after I ordered to explain that the 30T oval ring I ordered doesn’t fit, and did I want the 32T oval (yes, but which I haven’t installed yet) — that’s 5 star customer service right there. Thanks for saving me time and money!

    PS – don’t judge me for my new XX1 copper chain; I tore a tooth on my X01 52T cog so I replaced it with a XX1 copper cassette (yes, that hurt!) so the copper chain seemed a small conceit.

    If I could give this 3.5 stars I would. I bought it for the one bike that I own that won’t accommodate anything larger than a 24mm BB spindle. So a Quarq was out because they’re all DUB now, and I’ve got nothing good to say about my limited experience with Stages. So I was glad to be able to put this on an old GXP XX1 crank I had. After about 3 months on this PM, my conclusion is that it is better than Stages, worse than Quarq. It is two-sided power, which I think is important for mountain biking in order to accurately track power. This has proven to be pretty reliable so far, as well.

    For me, I’m not rating it five stars for a couple of reasons.

    The frame I bought this for has non-boost spacing. If you have a non-boost frame you have to pay $50 extra for the right version. What does that $50 get you? A purpose-built spider with a little more offset for a non-boost chainline? Nope. For $50 you get a kind of cheesy looking stamped metal ring that mounts between the spider and your chainring to correct the chainline of the boost-spaced spider. It works, but it’s ugly to look down at, and there’s absolutely no way it should cost you $50 extra. It probably costs about 50 cents to produce.

    Also–and this is hard to absolutely verify–I honestly think this PM reads low for really spiky efforts like mountain biking (which is of course what it’s made for). I know this assessment could be seen as an ego thing, but I say this because I have Quarq PMs on all of my other bikes, and they are all extremely consistent in the average and normalized power numbers they churn out. This PM consistently reads a bit lower on average power, and about 20w (about 8-10%) lower for NP on the same training rides. This isn’t a big issue for an hour-long ride, but if you’re doing a 4-6hr ride that 8-10% will really affect the accuracy of your TSS for that ride. Again, it’s hard to verify this absolutely because there’s no controlled environment. But with 3 months of riding and a bit of racing on the thing, I’m finding that I can consistently expect this discrepancy. I’m not sure what to attribute it to. Another reviewer notes some lag in the data readout, and I’ve noticed this as well (at least compared to a Quarq—it’s on par with Stages). I don’t know if that means that short bursts of power don’t get fully read and that translates into lower average and NP numbers over the course of the ride, or what. But as I said, for me it’s become a pretty unmistakable conclusion. I’ve learned to just factor it into my interpretation of ride data on this bike.

    Having said all of this, I do have to acknowledge that this thing costs a little over half of what a Quarq Eagle PM costs, and I can live with its foibles at that price.

      Hi Dustin, thanks for the detailed review! We hear you on the adapter plate. It gets the job done, just not super fancy. However, we will say, in all of our years of testing, the power2max units have been some of the best we sell in terms of accuracy and reliability so I think you can trust the data. If you have questions or if there is anything else we can do, please let us know!

    Great powermeter. Excellent value for money comparing to other powermeters on the market.

    Just wanted to make an update. I love this power meter but also like running a 32 oval as opposed to a 34 oval or 32 or larger round ring. I checked with Garbaruk who verified that their 104 BCD 32 tooth oval ring is compatible with the P2M power meter. I ordered one and receive it yesterday (shipping is delayed 2-4 weeks). Skeptical, I put it on my bike and despite it not looking compatible at all, it runs smooth and works flawlessly. Of note, I am using it on a single speed with a SRAM 9 speed chain. There is no chain rub on the power meter at all and plenty of clearance. It did not look promising at first. The 32 tooth ring is similar to the Woolf Tooth 34 oval ring I have in that the bolt holes are raised/have a bit of an offset and integrated threads. The Garbaruk Oval also has 108% timing with 12% ovality, nearly the same as a Wolf Tooth oval. Just some FYI.

    I originally ordered the Garmin Rally XC 100 pedals. However, after I had already ordered them I got to thinking that I would most likely never switch them from bike to bike, probably bang them up quite a bit, and realized upon arrival that they were a bit bulkier and heavier than I thought they would be, even after reading the specs and reviews/discussions about them. I sent them back and ordered the Power2max NGECO and I am overly glad I did. First it is extremely light. It just works. Plain and simple. It took less than ten minutes to put it on my bike, pair it with my head unit and get it to do its’ thing. Probably the best power meter I have purchased.

    I do look at data but do not tend to analyze multiple minute sections of a ride. However, this thing is pretty darn solid and accurate for what I am using it for. Since I am using it on a single speed mtb (I know. Please do not chastise me too much) I am looking at data more on climbs and flats and less on rolling or downhill terrain. Also, I am using it for cadence. I do not have anything to go on to provide a comparison, but I have not noticed any drops, crazy fluctuations or power spikes like I did with my crank arm power meter on a bike I used to have. This thing is just flat out excellent!

    Finally, Power Meter City is THE place to shop for and purchase a power meter. I tweaked out a bit and most likely came across as a jerk when trying to return the Garmin pedals. Everything was overly smooth. The staff are responsive and polite and a refund for the Garmin pedals was issued quick! Like within a day! I do not believe that I will ever purchase a power meter elsewhere. There is no need to. Power Meter City has everything and anything a cyclist could want in regards to training and riding with devices that measure power data. Thanks fellas and my apologies for any frustration on your end!

    I purchased two of the NGeco power meters for my wife and my Scott Spark. Loved that it was compatible with the 3-bolt XX1 cranks that came on both bikes.

    EVERYTHING about the devices, from battery ease of access and replacement, battery life, to accuracy of units, robustness and durability, all excellent. Everything is fantastic and excellent in every way unless listed below:

    There appears to be the slightest lag in data-collection at the onset of pedaling after a period of not pedaling. It’s not just that the screen on my Wahoo Bolt is failing to display what’s happening, I don’t think. I think it’s that the power meter has a battery-saving feature that causes maybe a 1-second delay in collection and transmission of information to the bike computer/ head unit. This is a non issue unless you’re riding technical stop-and-go terrain like on a highly technical MTB run, or doing standing starts with a track bike or something.

    It’s good enough that I’m keeping it for both my wife and I. If I ever decide to test short-duration sprint power, I’ll just make sure I’m slowly soft-pedaling before hammering out the power, so that it doesn’t miss my first second or two of power output. No biggie. I’m just an enthusiast. 🙂
