power2max NGeco ROTOR ALDHU Carbon Track 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 Carbon Track 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!
In addition, this power meter crankset uses ROTOR’s first ever carbon crank arms! The ALDHU Carbon Crankset is crazy light, weighing 100 grams less than the ALDHU aluminum model. In addition, vertical and horizontal stiffness had been increased by 11% and 36%, respectively.

Advice From Our Staff:
This power meter takes our best-selling track power meter crankset and raises the bar with super lightweight and stiff carbon crank arms. It measures power from both legs, is accurate and very reliable. If it’s in your budget, we highly recommend it. We use power2max power meters on many of our own bikes.
Options For This Power Meter
Crank arms: The ROTOR ALHDU Carbon arms use a 30 mm spindle and are available in the following sizes:
- 155 mm | 165 mm | 170 mm | 172.5 mm | 175 mm
Other Versions to Consider
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 Carbon Track Power Meter Crankset. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics.
Aluminum NGeco Version: We also have the power2max NGeco ROTOR ALDHU Track Power Meter Crankset which features ROTOR aluminum crank arms. This version is more affordable, but the aluminum crank arms are not quite as nice. An advantage to the aluminum version however is they come in both 24 mm and 30 mm spindle sizes.
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.
Chainrings: This power meter is compatible with 144 BCD 5-bolt track chainrings. Please also note, the power meter requires threaded chainring bolts.
Bottom Bracket: This power meter uses a 30 mm road spindle and must be used with a 30 mm bottom bracket.
IMPORTANT - Although this power meter is designed to be used on the track, it uses a ROTOR ALDHU/VEGAST road spindle and therefore requires the use of a road bottom bracket for proper fitment.

*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.

Common Questions and Answers
Question: How do I determine what length my current cranks are so I can make sure I get the same size?
- Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.
