power2max NGeco ROTOR ALDHU Carbon Gravel Power Meter Crankset
The power2max NGeco ROTOR ALDHU Carbon Gravel Power Meter Crankset brings power to your gravel bike! Using GRX spacing with a narrow road Q factor, the power2max Gravel power meter allows you to run a 1x or 2x chainring based on your needs. It features dual leg power measurement, ANT+/Bluetooth SMART compatibility and left/right power balance. 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 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.
Key Product Details
This power meter uses a 30 mm spindle and is therefore compatible with 30 mm bottom brackets. It comes with power2max gravel chainrings and features a GRX 47 mm chainline. The power meter gives you a narrow road Q factor vs. the slightly wider Q factor inherent in GRX cranks. See Compatibility tab for more information.
The power2max power meter measures power at the spider and is therefore able to measure power from both legs.
Dual-leg power measurement, lightweight carbon crank arms, 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:
We highly recommend power2max power meters and use them on many of our own bikes. They measure power from both legs, are accurate and very reliable. While this carbon version is more expensive, it also makes it incredibly lightweight and stiff.

- 1x chainring sizes are: 38 | 40 | 42 | 44 | 46

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 30MM Gravel 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.
24 MM Spindle Version: We also sell the power2max NGeco ROTOR ALDHU 24MM Gravel Power Meter Crankset which uses a 24 mm spindle for customers that are using a Shimano 24 mm bottom bracket.
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.
- 1x chainrings: Compatible with 11- and 12-speed drivetrains (not compatible with SRAM 12-speed chains).
- 2x chainrings: Compatible with 9-, 10- and 11-speed drivetrains as well as with 12-speed Shimano, SRAM and KMC chains.
Bottom Bracket: This power meter fits Praxis M30 (30 mm/28 mm) bottom brackets. If you currently have a Praxis M30 MM crankset on your bike, you should be able to re-use your existing bottom bracket. However, if you are changing spindle sizes, you will need to replace your bottom bracket.

*Power Balance Upgrade
The power2max NGeco measures power from both legs right out of the box. However, with power balance, you can 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: Can I use this power2max Gravel power meter on a Shimano road drivetrain?
- Great question! This power2max Gravel power meter features a GRX 47 mm chainline. This is wider than the 44 mm chainlines used on Shimano road drivetrains such as 105, Ultegra and DURA-ACE. However, the chainline on this gravel crankset can be converted to the narrower 44 mm road chainline by use of a power2max MTB Adapter Plate. The adapter plate is placed between the power meter and the gravel chainring, which moves the chainring closer to the bike and gives you a Shimano road chainline.
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.
