power2max NGeco ROTOR ALDHU Carbon Road Power Meter Crankset

The NGeco is the newest model in the power2max line-up. With features such as dual leg power measurement, ANT+/Bluetooth SMART compatibility and left/right power balance, the power2max NGeco ROTOR ALDHU Carbon Road Power Meter Crankset comes fully-loaded. 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 fact, there is no other power meter that provides dual-leg power measurement plus these other features at this price point!

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.

 

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!

Options

BCD: This power meter is available in either a 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt Shimano in order to fit your choice of chainring sizes.

There is also an SL (super light) version of the 110 BCD 4-bolt Shimano which is 30 grams lighter than the regular 110 BCD 4-bolt Shimano version.

Crank arms: The ROTOR ALHDU Carbon arms use a 30 mm spindle and are available in sizes 165 MM, 170 MM, 172.5 MM and 175MM.

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).

Upgraded NG Version: While the NGeco you are viewing on this page is our go-to version for most cyclists, please note we also have the upgraded power2max NG ROTOR ALDHU Carbon Road Power Meter Crankset. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics.

 

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:

  • Mount the power meter to the cranks and tighten to factory specifications
  • Apply multi-purpose bicycle grease where necessary
  • Install chainrings on the power meter (if chainrings are ordered)
  • Apply power2max decal

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.

 

Tools Needed for Installation

You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.

  • 10 mm Allen key

Compatibility

Chainrings: The power fits 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt (Shimano) chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

Please note, the 110 BCD 4-Bolt (Shimano) version is compatible with all Shimano 4-bolt chainrings, including Ultegra 8100 and DURA-ACE 9200 chainrings.

What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.

Bottom Bracket: This power meter fits 30 MM bottom brackets. If you currently have a 30 MM crankset on your bike, you should be able to re-use your existing bottom bracket. However, if you are chaining spindle sizes, you will need to replace your bottom bracket.

*Power Balance Upgrade

The power2max NGeco measures power from both legs right out of the box. However, with power balance, you are able to see how much power each leg is generating individually. If this information is important to you, you can choose to upgrade the power meter at any time. (Please note, you can also purchase the NG version of the power2max which comes with this feature unlocked, along with a rechargeable battery and a longer 5-year warranty.)

You can upgrade your NGeco using the power2max app once you receive the power meter. The cost to upgrade is 50 euros.
