The power2max NGeco ROTOR ALDHU Carbon Gravel Power Meter Crankset brings power to your gravel bike! Using GRX spacing with a narrow road Q factor, the power2max Gravel power meter allows you to run a 1x or 2x chainring based on your needs. It 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.

In addition, this power meter crankset uses ROTOR’s first ever carbon crank arms! The ALDHU Carbon Crankset is crazy light, weighing 100 grams less than the ALDHU aluminum model. In addition, vertical and horizontal stiffness had been increased by 11% and 36%, respectively.

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.

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. While this carbon version is more expensive, it also makes it incredibly lightweight and stiff.

Other Versions to Consider

Aluminum NGeco Version: We also have the power2max NGeco ROTOR ALDHU 30MM Gravel Power Meter Crankset which features ROTOR aluminum crank arms. This version is more affordable, but the aluminum crank arms are not quite as nice. An advantage to the aluminum version however is they come in both 24 mm and 30 mm spindle sizes.

24 MM Spindle Version: We also sell the power2max NGeco ROTOR ALDHU 24MM Gravel Power Meter Crankset which uses a 24 mm spindle for customers that are using a Shimano 24 mm bottom bracket.

 

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:

• Apply multi-purpose bicycle grease where necessary
• Install chainrings on the power meter (if chainrings are ordered)

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.
