power2max NGeco SRAM Road 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 Road 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 $490!

Regarding chainrings, it fits 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. 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.

Advice From Our Staff:

This is a great way to add power to a SRAM 3-bolt crankset. They measure power from both legs, are accurate and very 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

BCD: This power meter is available in the following BCDs in order to fit your choice of chainring sizes:

  • 110 5-Bolt | 130 5-Bolt | 110 4-Bolt


Other Versions to Consider

Upgraded SRAM 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 Road Power Meter. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics.


Cranksets: The power2max NGeco SRAM Road Power Meter is compatible with SRAM S-900, Force 1, Force 22, Rival 1, Rival 22 and CX1 cranks with a 3-bolt interface. This power meter does NOT fit Cane Creek eeWing cranks.

Chainrings: This power meter is compatible with 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

  • Note 1 - Please note, the 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Ultegra 8100 and DURA-ACE 9200 chainrings.
  • Note 2 - Some SRAM cranksets come equipped with direct mount chainrings. In this case, you will need to purchase new chainrings as direct mount chainrings won't work with a power meter spider. We have several chainrings to choose from on our Chainrings page.
  • Note 3 - This power meter is not compatible with SRAM Red cranksets or SRAM 1X 40T chainrings (however we do sell Praxis 1X 40T chainrings that will work).

What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.

*Power Balance Upgrade

The power2max NGeco measures power from both legs right out of the box. However, with power balance, you can 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.

    This is the third power meter I have bought from Power Meter City and I couldn’t be happier! Their advice steered me to the Power2Max NG ECO for my SRAM Force 1x group and it works like a charm. Very easy to install, got it up and running, paired to my head unit, updated firmware in no time. The power meter itself works great and the power aligns with my other power meters.

    Could not be more pleased with the advice I received and the power meter I bought. Great team at Power Meter City!

    • Power Meter City

      Thank you so much, Chris! We also want to thank you for being a great and loyal customer – it was a pleasure doing business with you! We hope you will continue to enjoy them and please let us know if there is anything else we can help you with! Ride safe!

  3. Dan

    I hit these guys up at power meter city with a bunch of questions regarding compatibility when I was having issues getting answers through my own country’s power2max distributor. They were more than helpful to sort me out with advice on which model to get, and included advice on running a Praxis 1x chainring instead of my SRAM 1x 40t due to chainring fitment issues.

    The power meter itself is fantastic – I’ve put a few hundred kilometers on it so far and it’s just worked flawlessly!

    • Power Meter City

      Great job Dan! Thank you for this awesome review on your new power2max NGeco SRAM Road Power Meter – looks like you are enjoying them. Good luck on your rides and please if there is anything else we can do, let us know!

  5. Joe Doherty

    If you’re looking for a PM that you install and forget about, then this is the one. It’s easy to set up and works flawlessly. I’ve read concerns about the battery cover; I haven’t had any issues and don’t feel like there will be. I can’t say enough good things about Power Meter City. Superb customer service, quick shipping, and excellent products. Will gladly shop here again.

    • Power Meter City

  7. Jamison Sheppard

    After using this power meter for 2500 miles and not changing the battery once or having a single issue with drops or accuracy I’m 100% sold on Power2Max. It’s a breeze to setup, auto calibrates, and has incredibly long battery life.

    • Power Meter City

      Hi Jamison. Agreed! One of the best quality the power2max NGeco SRAM Road Power Meter have! We hope you continue to enjoy them and please let us know if there is anything else we can help you with!

  8. BMak (verified owner)

    Best value for the money I could find! Been using it on my Canyon Grail Gravel bike for a few months now and couldn’t be happier. I had a few questions with power2max that were quickly answered… now looking at a second power meter for my road bike…

    Preferring was smooth and shipping easy peasy.. would do business again!

    • Power Meter City

      Hi BMak. Good job and good luck on your future rides! We are glad you are enjoying you power2max. Please let us know if there is anything else we can do!

  9. Travis Garrison (verified owner)

    I own 4 powere meters, 2 are Power2max. Best PM I own!! Easy install, no hassle calibration and works great. Got a year out of a battery on my other P2M. I would buy for any future bikes. Shipping is faster than expected.

    • Power Meter City

      Hi Travis! Good job! Thank you for leaving as an awesome review too! We hope you continue to enjoy them and please let us know if there is anything else we can do!

  10. Jessica S. (Japan) (verified owner)

    This Power2Max NG-eco SRAM is my first powermeter and it took several years to convince myself to do it. Powermeters are not cheap but the P2M NG-eco is one of the best performance to price out there. Despite the world situation now in April-2020, PowerMeterCity was great to deal with and shipping was fast and trouble free to Japan. It was easy to install on my Force22 and I was up and running in Zwift very smoothly. This is a high quality power-meter and I am looking forward to many years of improved training in Zwift and on the road with it.

    • Power Meter City

      Hi Jessica. Thank you for this amazing review on your power2max NGeco SRAM Road. Good choice for your first power meter – one of the best! We hope you continue to enjoy them and let us know if there is anything else we can do! Thank you.

  11. Alvin Runas (verified owner)

    My first powermeter was an SRM which I now transferred to my other road bike. It was super accurate and “just worked”, I never had any problems using it for 8 years. I have tried other meters which didn’t quite measured up to standards, until this power2max NGeco SRAM Road. This meter is easy to install, very accurate, and works every time. Also, Its cheaper than Quarq offerings and offering about the same qualities: autozero, bluetooth and ant+, but without the need to swap to an new bottom bracket standard (DUB). I 100% recommend this. Don’t waste your money on other meters, this is all you need right here.

    • Power Meter City

      Hi Alvin. Thank you for this amazing review on your power2max NGeco SRAM Road Power Meter. We hope you continue to enjoy them and let us know if there is anything else we can do!

    Really great experience so far with the power2max NGeco and PowerMeter City. The guys were really helpful and the power meter has been reliable, easy to install and use.

    • Power Meter City

      Hi Brad. Thanks for the review. This is one of our best-selling power meters. power2max is just a wonderful unit and is priced competitively as well. Let us know if there is anything else we can help you with!

  13. Rick Borns (verified owner)

    Excellent service and product from PMC. Josh and team are super responsive, went through extra measures to make sure the PM was compatible with my bike a I’m loving the PM itself. Just completed my first race (Barry Roubaix 62 mile gravel race) with the PM installed and it was so nice to have the power data available in order to pace myself as needed for this endurance event!

    • Power Meter City

      Hi Rick. Thanks for the review and I’m glad your power2max SRAM is working as intended. Keep up the nice work!

  14. Jeevan Philip (verified owner)

    Amazing customer support! I was routinely updated on the progress of my P2Max as Power Meter City did their best to mail me the power spider as quickly as possible. I am extremely grateful for their extensive knowledge, making sure I had the exact item I needed. Works flawlessly when compared to my other power meters! Definitely the best place to get a hookup on watt-meters.

    • Power Meter City

      Hi Jeevan. The p2m units rock – they really do. You get consistent, reliable, dual-sided power at a great price. We appreciate you being a great customer and hope you continue to enjoy it!
