power2max NGeco Praxis 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 Praxis 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 $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!


BCD: This power meter is available in either a 110 or 130 BCD in order to fit your choice of chainring sizes.



Crankset: The power2max NGeco Praxis Road Power Meter is compatible with the new Praxis direct mount cranksets: Zayante M30, Alba M30 and Zayante Carbon M30. These cranks can also be identified by 3 bolts located on the inside of the spider which are used to secure the spider to the crank arm.

Chainrings: This power meter requires a 5-bolt 110 or 130 BCD chainring (depending on the version you select). In most cases, you can use your existing chainrings assuming they have this same configuration. Please note, some Praxis cranksets come equipped with direct mount chainrings. In this case, you will need to purchase a new 5-bolt chainring as direct mount chainrings won’t fit a power meter spider (we have several chainrings to choose from on our Chainrings page).

Please also note – This power meter is not compatible with Praxis 48/32 chainrings.

    Excellent power spider to go on my gravel rig. PMC pre-fitted my Praxis 1x ring and all I had to do was install my cranks and go! Ordering was very easy and product arrived in a very timely manner. Very happy and will definitely order from PMC again!

    10 minute install, works flawless! Have it on my Rodeo Labs Trail Donkey, and it works perfectly!

    This thing is great! I have previously used a Powertap hub and SRM crank based power meters and this works equally as well and has the best appearance to boot. It starts and connects quickly and is very accurate.
    I would add the the service is great too. I ordered with a chaining and bolts, all of which was installed and ready to go. I had it mounted in 15 minutes.
    This will be where I get a PM for my mountain bike.

    First power meter from Power2Max and I’m very happy with it for the few rides that I’ve used it on. The crank based power meter was easy to install and quick to setup with my Garmin. Install is very simple with just the three bolt to attach to the crank and then the bolts to mount the chainring. Did a 52 mile ride in the heat and power really helps keep you in the right zone and not over or under perform. Great service from Power Meter City as well!

    This is my second Ngeco power meter from Power Meter City. I have one on each of my two Crux (CX). One is a Sram CX 1 and the other is for a Praxis carbon crankset. I have been very happy w both of them. There have been no problems over the 4 months i’ve been using them several times a week. Im very happy w the accuracy as well. It tracks very closely w the dual crank based power meter on my road bike. Im very satisfied w the German engineered PM and the service provided by Power Meter City.

      Hi Robert. Your review made our day. The power2max series of power meters are some of our best-sellers. Just simple, affordable and totally accurate. Keep up the nice work!
