March 11, 2023$590.00 – $610.00
The best-selling ROTOR ALDHU crank with more budget friendly p2m Edition crank arms
power2max NGeco ROTOR p2m Edition 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 p2m Edition Road Power Meter Crankset comes fully-loaded. 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!
Key Product Details
Compatibility:
This power meter fits 24 MM bottom brackets and 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.
For Shimano Users:
If you currently have a Shimano road crankset on your bike, this power meter is a direct replacement. If you select one of the 24MM ALDHU crank sizes, it 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 BCD option, you can also use your current Shimano chainrings on it. This makes replacing your Shimano crankset very simple and easy.
ROTOR p2m Edition vs. ROTOR ALDHU 24 MM
We offer this power meter with both ROTOR power2max Edition (what you are viewing now) and ROTOR ALDHU crank arms. These crank arms work and fit the same, however power2max Edition is a slightly more budget friendly version of the ROTOR ALDHU version. The slightly more expensive ALDHU version has a nicer finish and they are about 40 grams lighter.
Power Measurement:
The power2max power meter measures power at the spider and is therefore able to measure power from both legs.
Key Features:
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 one of our best-selling road power meters, slightly behind the ROTOR ADLHU version. 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 | 130 5-Bolt | 110 4-Bolt
Crank arms: You can get this crankset in the following crank arm lengths:
- 165 mm | 170 mm | 172.5 mm | 175 mm
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).
Other Versions to Consider
Aluminum NGeco Version: We also have the power2max NGeco ROTOR ALDHU Road Power Meter Crankset which features ROTOR aluminum crank arms. This version is more expensive, but the aluminum crank arms are nicer (about 40 grams lighter, nicer finish and stiffer).
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.
Compatibility
Chainrings: The power fits 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.
The 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Shimano 12-speed 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 uses a 24 mm Shimano road spindle and must be used with a 24 mm Shimano bottom bracket.
Tip - If you already have a Shimano crankset on your bike, then this power meter will fit your bottom bracket perfectly as all Shimano cranksets use a 24 mm spindle.

*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.

I chose this product because I use mountain bike pedals (i.e., SPD) when riding outside and I wanted to measure power generated from both legs. For a Shimano user, this is the only option I know that can meet my needs. And Power Meter City was the only place where you can buy this product from Japan. To install, I had to buy a Torx wrench at a local DIY store, but other than that, it was a simple process. I had a trouble at the first ride, which was that the chain kept falling when shifting to the inner ring. But it seemed to be my mistake. I found that the drive-side crank arm bolt was loose. The problem has not occurred since I tightened it properly. We should keep checking this bolt once in a while. So far I’m satisfied and thank you very much, Power Meter City people!

Arrived faster than expected and looking great. After watching a YouTube video, it took under 15 minutes to install.
Jumped on the trainer and verified it measured power identically to my trainer when indoors. Couldn’t be happier with my choice.
Power Meter City –
That’s great news! Thank you for this kind review, Christopher. We hope you will continue to enjoy your new crankset and please let us know if there is anything else we can do!
H.Y (verified owner) –
This power meter is the first choice for users with Shimano cranks.
This Rotor comes with a 24mm spindle. Compatible with Shimano bottom brackets, changing cranks is a breeze.
The combination of Rotor’s cranks and P2M is very sturdy. No worries in normal use.
I am replacing my Pioneer power meter and the power readings seem to be a few dozen watts lower than the Pioneer. (This may be my unique situation).
The one purchased from Power Meter City came with a black sticker; you can purchase stickers in different colors to match the color of your bike from Power Meter City accessories.

Thank you, H.Y – we really appreciate it. Your crankset looks amazing! Please let us know if there is anything else we can do! Ride safe!

Great power meter but had some pretty severe connectivity problems with both Zwift and even Power2Max’s own app intially where connection would just die 30s on the bike. Had to dismount the bike, pop battery on and out and literally sit nezt to powermeter with my phone for connection to take (very bad). Did firmware upgrade and issue largely (9 times out of 10 connection takes quickly and stays on whole workout now) went away just a shame Product would be shipped to customer with such garbage firmware at all.
Power Meter City –
Hi Stanislav. Thanks for the review and glad you like the power meter. We run p2ms on many of our own bikes here and they are wonderful units. It’s strange about the firmware issue. The firmware that shipped on your power meter is the same version that thousands of other customers are currently using without issue, but I’m glad you got it resolved by updating the unit. I hope you continue to enjoy it!

This is my second NGECO. Shipment was pretty quick and installation on my Trek Emonda with a T47 BB was straightforward. Power meter is consistent and reliable across a wide range of cadences and can easily handle 1900+W, unlike other power meters which I have broken.

Thank you for this kind review, Ken. We hope you will continue to enjoy your new power2max NGeco ROTOR p2m Edition Road Power Meter Crankset. If there is anything else we can do, please let us know! Ride safe!

This is my first power meter and it serves its purpose. The RPM and power data is very useful for training. Already, I can tell that my indoor trainer workouts are going to be much more productive this winter. I can’t speak to its accuracy since I have no comparison, but I have no reason to doubt it.
The UI of the accompanying Power2max NG app is a bit disappointing. It looks like an amateur developer made it. But I don’t think I’ll be using the app very often so it’s not a big deal.
I appreciated the affordability of this model and its compatibility with my Shimano R8000 crankset and BB. However, the installation on my Canyon Endurace was painful. I’m not sure if the spindle was on the larger end of spec or if my BB was on the smaller end of its spec, but I couldn’t get the spindle to fit without hammering it in with a metal hammer and wood block. It definitely did not go as smoothly as the installation videos showed for this power meter. That’s the only reason I’m taking off one star. Otherwise, it serves its purpose for a great price!
