power2max NGeco ROTOR p2m Edition 24MM Gravel Power Meter Crankset

The power2max NGeco ROTOR p2m Edition 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 p2m Edition 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.


ROTOR p2m Edition vs. ROTOR ALDHU

Both cranks are a direct replacement for your Shimano crankset and use a 24 mm spindle. They can also be installed with requiring any special tools. The ROTOR power2max Edition is just a slightly more budget friendly version of the ROTOR ALDHU crank.



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 power2max Edition 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).


Tools Needed for Installation

The following tools are typically required for installation of this product. You can purchase many of these commonly used tools in our store.

  • 10 mm Allen key


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.

    Very good service and fast shipping, after testing, this power meter is very accurate and the balance is pretty good, but be aware that 48/31 is a better choice

  2. TonyP

    This was the perfect set up to replace my GRX crankset on my new Aspero. This gravel specific powermeter has the correct chainring spacing for the GRX specific front der. Also the guys at PowerMeterCity were really patient and helpful.

    • Power Meter City

      Thanks Tony! Totally agree with this – these crankset rocks! We hope you will continue to enjoy them, and if there is anything else we can help you with, please don’t be hesitant to let us know! Ride safe!

    This was just want I needed for my Lynskey GR300 build with GRX Di2. The install was easy, the power meter works perfectly, and Power Meter City service was second to none. I didn’t have the chainstay clearance to go with a left side crank PM as I’ve used on prior bikes so this was a great alternative.

    • Power Meter City

      Awesome! Thanks for this Mike! Agreed! We hope you will enjoy them – good luck on your rides! We are here if there is anything else we can do.
