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.
