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!



Dual-Leg Power Measurement

The NGeco power meter measures power at the crank spider. This means it measures both left and right leg power.

Accurate to +/- 2.0%

The power2max is always consistent and accurate, regardless of the environmental conditions.

Long Battery Life

The power meter gets 300-400 hours of run time off of a single CR2450, user-replaceable battery.

Left/Right Power Balance

In addition to measuring both legs, the NGeco can also provide left/right power balance with a system upgrade.


Featuring both ANT+ and Bluetooth SMART, the power meter can be used with virtually any bike computer or smart phone.


With the auto-zero feature, you never have to worry about manually calibrating the unit. Just get on and go!


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

  • 1X Standard | 104 BCD
  • 1X Boost | 104 BCD
  • 2X Standard | 104/64 BCD

Tip – If you have a 148 mm rear hub, your bike has boost spacing. If you have a 142 mm rear hub, your bike has standard spacing.

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.


Tools Needed for Installation

You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.

  • T25 Torx bit
  • 8 mm Allen key


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 then the direct mount chainrings found on many SRAM MTB cranksets). If you don't already have a 4-bolt chainring, we offer several different MTB chainrings for power2max.

IMPORTANT: The smallest chainring that will fit on a power2max MTB power meter is a 32T round or a 34T oval. The exception to this is the Garbaruk 30T MTB Chainring (also found on page above) which is specifically designed to fit a power2max power meter.

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.

    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.

      Thank you, Heine. We really appreciate this! If there is anything else we can do, please let us know!

    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. 🙂

  9. Camilo Placencia (verified owner)

    First I want to say that I have used 4 different powermeters in the past, 1 left sided only and 3 spider based. This is by far the best. I have been using it for about 150 miles a week for 3 weeks now and the battery is still at 100%. Power reading to my garmin 1030 is super fast. I have put it through some rough temperature changes and have not had to stop and recalibrate like with others. I have not experienced any spikes or drops. Just perfect. It was shipped super fast and priced very good.

    • Power Meter City
