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 chainring 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.

    Leave a review again for installation.

    When I got my P2M, I couldn’t find an appropriate torque value to mount on the bike, so I found the torque value through the manufacturer.

    The torque value between the P2M and the chainring is 7-8nm (alloy chainring). And, unbelievably, the torque between P2M and the crank is 2-3nm. I couldn’t believe it, but the manufacturer confirmed it again via E-mail. And I tightened it to 3nm and there was no problem with about 200 miles of riding.

    You can also get a L-R balance upgrade from the P2M website for 50 euros, and I am very satisfied with this upgrade. Pedal smoothness can also be upgraded paying 50 euros.

    Hope my review helps others too! It works very well with my MTB and I am very satisfied.

    About the customer service just can say is awesome, everything is fast and you feel confident what are you buying, this is my first ngeco power meter looks great and the possibility to use it in a sram 3 bolt crank is great, I installed it in my enduro bike so I like aluminum cranks, fits perfect and the accuracy is quite similar to my quarq on my gravel bike, it is for far the best option if you want to keep your aluminum crank, it pairs perfect with garmin, needs more time to can give a opinion about battery life and durability in general.

    I bought it in South Korea.
    Josh said the USPS deliver could be slow, but they delivered my P2M in one week!!
    And Josh’s customer service was quick and friendly.
    The power meter works well with my WAHOO. I am willing to purchase other power meters or any other MTB accessories next time.
    I am very satisfied, really appreciate.

    I purchased this for my mountain bike because of the 3 Bolt SRAM Eagle compatibility. The power meter has been great so far, very accurate, easy to install, no fuss calibrating. Very happy with P2M. Power Meter City shipped fast and installed the chainring to the power meter before shipping it out. Great service, happy to shop with you.

    Awesome power meter, Power2Max works straight out of the box, connects every time to my Garmin. I live in New Zealand and the guys here were fantastic to deal with, gave me suggestions via live chat and had it packed and posted super quick. Thanks Brent

  7. Alex (verified owner)

    This was 5th or 6th power meter, but first time using Power Meter City and the experience was top notch. The agents were helpful in determining compatibility, the ordering and shipping process was quick and easy, and then the item came in perfect condition. It’s my first time using a P2M power meter, so we’ll see how that goes over the next year, but so far everything has been great!

  9. MORGAN STEBBINS (verified owner)

    I found the sales help to be very friendly and knowledgeable- I ended up with just what I needed. The P2Max unit itself seems very well made and was a breeze to put on (apart from the SRAM crank being hard to take off, just have to use a good lever). It was linked easily to my Garmin and has worked flawlessly!

    • Power Meter City

      Hi Morgan. Thank you for the great review. We hope you continue to enjoy your power2max and are here if you need anything else!

  10. Aiyaaz Dollie (verified owner)

    So far so good for my first power meter purchase. Put about 10 hours of use on the unit thus far with no drop outs. The numbers line up very closely with my Kickr18 based on a quick little test I did. Easy to install and the auto-zero feature is very handy.

    • Power Meter City
