Advice From Our Staff:

In addition to being one of the only power meters for a ROTOR road 30 mm crankset, it’s a great option. It measures power from both legs, is 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 | 110 4-Bolt

Lock Ring Tool: This page also allows you to purchase your power meter with the power2max Lock Ring Tool for ROTOR, which is required for installation. We recommend you order it unless you already own one. Note the tool is 50% off when you bundle it with a power meter on this page.


Cranksets: The power2max NGeco ROTOR 3D+ Road Power Meter is compatible with all 30 mm ROTOR cranks including 3D+, 3D30, 3DF and FLOW.

Chainrings: This power meter is compatible with 110 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.

Please note, the 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Ultegra 8100 and DURA-ACE 9200 chainrings.

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 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.

    Excellent power meter for the price. +- 2% is really all you need unless you’re pro. Reliable data with no real outliers and the app supporting it is decent too.

    Josh was great! He helped me through the whole buying process and emailed me personalized videos explaining all I needed to know to install the POWER2MAX NGECO ROTOR 3D+ ROAD POWER METER. He made sure I had all the tools too. The installation went smoothly. I just took my first ride. The power meter worked great!

    I highly recommend Power Meter City and Josh.

    Thanks Josh!

    I chose power2max NGeco as my first power meter based on information provided on Power Meter City’s website. My shipment arrived fast with everything needed to install. Installation took less than 15 minutes, including syncing with my Garmin 1030. The unit works great. I will continue to upgrade my bikes with power2max power meters purchased from Power Meter City in the future. Thank you for the great service.

      Hi Corey. We are glad you are enjoying your power2max and good choice on your first power meter! Please let us know if there is anything else we can do.

    Looking for a power meter, I ran across this on the Powermetercity website. Two days later, I had it in my hands. I paired it up to a Wahoo Element Bolt, and it synced up right away. I had the meter installed on my bike, and took my first ride with it. It is very accurate, and looks great on the bike. Highly recommend the meter and Powermetercity.

    Great product and works just as expected. I’ve run this product against smart trainers and the data analysis comparisons are fantastic!! And all of this at a great price!!

      Hi Billy. Glad to hear you liked your p2m NGeco ROTOR 3D+. Those are really good power meter. We hope you continue to enjoy them and let us know if there is anything else we can do.

    Was planning on buying the Vector 3 or the Favero Assioma, I don’t regret buying NGeco, it has been providing constant power/cadence reading without any problems for half the price of the pedals. I have a Garmin Edge 1030 and it synced up instantly. The best part of the device is if you need anything else (left/right balance or pedal smoothness) you can upgrade the firmware through you app. With 2 year of warranty you can’t ask for anything else. Highly recommended!

    • Power Meter City

      Hi Melvin. It’s great to hear your p2m NGeco ROTOR 3D+ is working out for you. They are such nice power meters – simple, reliable and accurate. Keep up the good work!
