power2max NGeco ROTOR 3D24 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 ROTOR 3D24 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!



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 comes in a 110 5-Bolt BCD.

Lock Ring Tool: The Lock Ring Tool for ROTOR is required for installation. We recommend you order it unless you already own one.



The power2max NGeco ROTOR 3D24 Road Power Meter is compatible with your existing ROTOR 3D24 crankset.

    I originally purchased the 3D24 but then found out it was being discontinued so I upgraded to the ALDUH 24. The power meter is exactly the same, just a different crankset. I’m very happy with both of them and would and have recommended both. The ease of installation, set up and readings of the PM are second to none. This old style crank requires a special tool, the new ALDUH does not. The P2M reads within 1% of my kickr trainer and helps me know that the numbers are accurate on the road.

      Hi Justin. Thanks for the review. If you already have a ROTOR 3D24 crankset, this p2m ROTOR 3D24 power meter spider will work great with it. However, if you are replacing your entire crankset, we agree that the new ALDHU cranks are a nice improvement over the 3D24 cranks. I’m glad you’re enjoying it!
