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.

Key Product Details
The power2max NGeco Praxis Road Power Meter is compatible with Praxis direct mount cranksets. Direct mount cranksets have drive-side crank arms that can be removed from the crankset. In addition, if you were to view the backside of the crank, you would see three small bolts or screws that secure the crank arm to the spider or chainring. 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.
The power2max power meter measures power at the spider and is therefore able to measure power from both legs.
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 a great way to add power to a Praxis 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 Praxis 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 Praxis Road Power Meter. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics.
Crankset: The power2max NGeco Praxis Road Power Meter is compatible with Praxis direct mount cranksets. Direct mount cranksets (left image) have drive-side crank arms that can be removed from the crankset. In addition, if you were to view the backside of the crank, you would see three small bolts or screws that secure the crank arm to the spider or chainring.
Standard cranksets (right image) have a one-piece drive-side crank arm and spider. That is, the crank arm and spider are one solid piece of aluminum.
Most modern Praxis cranksets are direct mount. This includes Zayante M30, Alba M30 and Zayante Carbon M30. It's very important you confirm you have a direct mount version where the drive-side crank arm can be removed. If you are not sure, please send us some images of your crankset and we would be happy to confirm for you.
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.
Important chainring notes:
1) Some Praxis cranksets come equipped with direct mount chainrings, while others come with LevaTime 160/104 BCD chainrings. In either case, you will need to purchase new Praxis Works Buzz Road Chainrings or Praxis Works Buzz Sport Road Chainrings as direct mount or LevaTime chainrings won't work with a power2max power meter. If you are not sure if your current chainrings will fit, please contact us so we can help.
2) This power meter is not compatible with Praxis 110x5 48/32 chainrings. This is because the 32T chainring is smaller than the diameter of the power meter. 110x5 50/34 is the smallest chainring 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.
