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.

 

Highlights

Dual-Leg Power Measurement

The NGeco power meter measures power at the crank spider. This means it measures both left and right leg power.

Accurate to +/- 2.0%

The power2max is always consistent and accurate, regardless of the environmental conditions.

Long Battery Life

The power meter gets 300-400 hours of run time off of a single CR2450, user-replaceable battery.

Left/Right Power Balance

In addition to measuring both legs, the NGeco can also provide left/right power balance with a system upgrade.

ANT+ & BLE

Featuring both ANT+ and Bluetooth SMART, the power meter can be used with virtually any bike computer or smart phone.

Auto-Zero

With the auto-zero feature, you never have to worry about manually calibrating the unit. Just get on and go!

    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
