power2max NGeco ROTOR ALDHU 24MM Gravel Power Meter Crankset

The power2max NGeco ROTOR ALDHU 24MM Gravel Power Meter Crankset is the go-to gravel power meter for bikes with a Shimano GRX crankset. Using the same 24MM spindle as your GRX crankset, this power meter will fit your current bottom bracket without any changes. Even better, the power meter gives you a narrow road Q factor vs. the slightly wider Q factor inherent in GRX cranks and allows you to run a 1x or 2x chainring set-up.

Like all power2max power meters, the p2m ROTOR ALDHU Gravel crankset 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.

 

Key Product Details

Compatibility:

This power meter is a direct replacement for your Shimano GRX crankset. It uses a 24 mm spindle and fits Shimano 24 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.

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:

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. We believe the price also represents a good value for what you get.

 

Options For This Power Meter

Chainrings: You can order this power meter in a 1X or 2X chainring configuration.

  • 1x chainring sizes are: 38 | 40 | 42 | 44 | 46
  • 2x chainring sizes are: 46/30 | 48/31

Crank arms: The ROTOR ALDHU 24 mm crank arms come in the following crank arm lengths:

  • 155 mm |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

Budget Friendly p2m Edition Crank Arm Version: We also sell the power2max NGeco ROTOR p2m Edition 24MM Gravel Power Meter Crankset which comes with more budget friendly crank arms. The finish on the p2m Edition arms is not quite as nice and they are about 40 grams heavier.

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 24MM Gravel Power Meter Crankset. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics.

30 MM Spindle Version: We also sell the power2max NGeco ROTOR ALDHU 30MM Gravel Power Meter Crankset which uses a 30 mm spindle.

 

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

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.

    The shipping to Australia was very fast and the customer support was great. The product was very easy to install and takes way less time than they say to allow for. The power meter has operated flawlessly over the 6 months that I’ve had this on my bike, and I’m very happy to recommend it to anyone looking for an easy power meter option for a GRX groupset.

    • Power Meter City

  6. John Hintz (verified owner)

    This is my first power meter and I couldn’t be happier with it, or with the service/help I got from Power Meter City. I installed it myself (and I am by no means a bike mechanic), using videos on removing the Shimano crank and another video from Power2max on installing the Rotor Aldhu power meter crank. It was pretty darn easy. It shifts smooth as butter, just like the GRX crank it replaced. So far, so good! Thanks, Power Meter City!

    • Power Meter City

      Hi John. Welcome to power! Good choice on your first power meter! Good luck on your rides and we hope you will enjoy your power2max NGeco ROTOR ALDHU 24MM Gravel Power Meter Crankset! We are here if there is anything else we can do!
