power2max NGeco ROTOR ALDHU Road Power Meter Crankset

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 ALDHU Road Power Meter Crankset 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 this price point!

 

For Shimano Users

This power meter can serve as a direct replacement for Shimano road cranksets. If you select one of the 24MM ALDHU Crank sizes, this power meter will come with the same spindle size as your current Shimano crankset and will fit your bottom bracket without any changes. In addition, if you select the 110 4-Bolt Shimano BCD option, you can also use your current Shimano chainrings on it. This makes replacing your Shimano crankset very simple and easy.

 

Highlights

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.

ANT+ & BLE

Featuring both ANT+ and Bluetooth SMART, the power meter can be used with virtually any bike computer or smart phone.

Auto-Zero

With the auto-zero feature, you never have to worry about manually calibrating the unit. Just get on and go!

Options

BCD: This power meter is available in either a 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt Shimano in order to fit your choice of chainring sizes.

There is also an SL (super light) version of the 110 BCD 4-bolt Shimano which is 30 grams lighter than the regular 110 BCD 4-bolt Shimano version.

Crank arms: You have the option of either ROTOR ALDHU 24 mm crank arms (uses a 24 mm spindle) or ALHDU 30 mm crank arms (uses a 30 mm spindle). In addition, each of these cranks comes in a wide range of crank arm lengths.

Please note – this power meter ships with a Black decal. Please let us know if you would like us to include a different color instead (Red, Blue, White, Green).

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

 

Professional Assembly (Optional)

We are happy to professionally assemble your power meter crankset if you select this option when ordering. This ensures your crankset is correctly built and saves you time. Professional assembly includes:

  • Mount the power meter to the cranks and tighten to factory specifications
  • Apply multi-purpose bicycle grease where necessary
  • Install chainrings on the power meter (if chainrings are ordered)
  • Apply power2max decal

Please note – while we tighten everything to factory specs, it is still your responsibility to routinely check your power meter crankset to make sure all bolts and nuts remain securely fastened.

 

Tools Needed for Installation

You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.

  • 10 mm Allen key

Compatibility

Chainrings: The power fits 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt (Shimano) 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 (Shimano) 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.

Bottom Bracket: This power meter fits 24 MM or 30 MM bottom brackets, depending on the version ordered. If you are ordering the same size as you currently have on your bike, you should be able to re-use your existing bottom bracket. However, if you are chaining spindle sizes, you will need to replace your bottom bracket. Please contact us with questions, we are happy to help.

*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.

  1. Gregor (verified owner)

    Works perfectly. The team is awesome in providing you with the information you need to select the right power meter. It’s the second one I bought – now for the new Dura Ace Di2 12sp. Service impeccable as always. Fast delivery and straight forward installation. Just needs a little re-adjustment of the front derailleur, which is easy. Connects fast, Garmin immediately recognizes it. And here we go. Thanks for the great experience!

    • Power Meter City

      It was a pleasure doing business with you again, Gregor! Thank you so much for this kind review! We hope you will enjoy your new power2max crankset! Please let us know if there is anything else we can do! Thank you!

  2. Chris Cooper (verified owner)

    It’s not often these days you can email a company with questions and receive a such good customer service. I had all of my questions answered within a few hours and placed my order. Coming from a Quarq D-zero I was worried I would not have the same reliability but the Power2Max NGECO and Rotor Aldhu crankset have been rock solid. Great customer service and fast shipping.

    • Power Meter City

      Hi Chris, it was our pleasure! Thank you for being a great customer too! Nice ride BTW! We hope you will continue to enjoy your new crankset and if there is anything else we can do, please let us know!

  3. Andrew (verified owner)

    High quality cranks that were straightforward to install. The NGeco connects quickly, is responsive, consistent to my other power meters, and no connection drops to either my watch or computer. Excellent customer service and quick responses from the Power Meter City team during my shopping and buying process.

    • Power Meter City

      We really appreciate this Andrew! Looks like you are enjoying your new crankset! If there is anything else we can do, please let us know! Ride safe!

  6. Cy Shimizu (verified owner)

    Really enjoying the power meter and cranks. Have been using these for a few weeks, and knowing my power has really helped in my training. The shorter cranks are also a plus, as it’s helped some with some knee pain. Installation was a cinch.

    • Power Meter City

      Hi Cy. Good job on your training – good luck on your future rides! Thanks for taking the time to leave a great review on your power2max NGeco ROTOR ALDHU Road Power Meter Crankset. We are here if there is anything else we can help you with!

    Purchased the p2max NGeco ROTOR ALDHU crank several weeks ago. Power Meter City did an excellent job setting expectations when the unit should arrive and actually sent a very unique email video showing the shipping tracking from the p2max warehouse as it was slightly delayed. Thought it was a super clever method of communication.

    Josh on their customer service team answered a few follow up questions after the install. The full process was A+. Would absolutely recommend Power Meter City to anyone for their power meter needs.

    • Power Meter City

      Hi Dentoner. We are glad it finally arrived! Thanks for this awesome review – we really appreciate it! We also want to thank you for being a great customer! Let us know if there is anything else we can help you with!

  8. Sean Farrell (verified owner)

    Got my Power2Max NGECO mounted to a Rotor Aldhu 24 crankset today, got it mounted up, and took it for a ride. First, this unit is super simple to install, google Rotor Aldhu install for a video guide by the people at Power2Max. Second, this unit is super simple to setup and use. I spun it around to wake it up, my Wahoo recognized it right away, and I was off. Only minor hiccup was in the meantime between pairing it to my head unit and going out for the inaugural ride, I had connected to the PM with Power2Max’s app, which I think confused the PM and it wouldn’t send any data to my head unit. Once I force quit the app, power was back up on the head unit and I was off!

    Lastly, Power Meter City has been awesome throughout the entire buying process. I had a question before I bought, and Josh got back to me with a quick video answering my question. I’ve never had customer support send a video, which made Josh’s answer super clear, unlike a written email can be sometimes. I had a question about something while I was checking out, and Josh called me to clear up my question about a minute later. Shipping was super fast. I ordered mid afternoon (pacific time) Tuesday, and the unit was at my doorstep Thursday morning in Minnesota.

    I cannot recommend them enough. Excellent products and fantastic service. What more can you ask for?

    • Power Meter City

  9. Patrick C (verified owner)

    This power meter works very well with and it was easy to install. The package kit with the Aldhu cranks and axle was a really good value. I had some questions before I ordered which Power Meter City answered via the chat.

    • Power Meter City

    Amazing service, couldn’t ask for more. I would definitely recommend this site to my friends.

    Regarding the product, it’s flawless to my eyes, I’ve installed it in about 10 minutes, there are several youtube videos if you need assistance, but it’s really easy and without fuzz.
