power2max NGeco ROTOR p2m Edition 24MM Gravel Power Meter Crankset

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.

 

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.

ROTOR p2m Edition vs. ROTOR ALDHU

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.

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.
