Key Product Details

For Shimano Users:
If you currently have a Shimano road crankset on your bike, this power meter is a direct replacement. If you select one of the 24MM ALDHU crank sizes, it will come with the same spindle size as your current Shimano crankset and will fit your bottom bracket without any changes. In addition, if you select the 110 4-Bolt BCD option, you can also use your current Shimano chainrings on it. This makes replacing your Shimano crankset very simple and easy.
The power2max power meter measures power at the spider and is therefore able to measure power from both legs. This NG version is also able to measure your left vs. right leg power balance.
Dual-leg power measurement, accurate to +/- 1.0%, 150 hours of battery life, rechargeable battery, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration), 5-year warranty. See Specs tab for more information.
Advice From Our Staff:
This is one of our favorite road power meters. The NGeco version of this crankset is a best-seller and is a great power meter, but this NG raises the bar even further with improved accuracy, additional training metrics, a longer warranty and more. It’s also more expensive. If it’s within your budget, we highly recommend it.
Options For This Power Meter
BCD: This power meter is available in the following BCDs in order to fit your choice of chainring sizes:
- 110 5-Bolt | 130 5-Bolt | 110 4-Bolt | 110 4-Bolt SL
Note – The SL (super light) 110 BCD 4-bolt version is 30 grams lighter than the regular 110 BCD 4-bolt version.
Crank arms: You have the option of either ROTOR ALDHU 24 mm crank arms (uses a 24 mm spindle) or ALHDU 30 mm crank arms (uses a 30 mm spindle). Each of these cranks comes in a wide range of crank arm lengths.
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).
Other Versions to Consider
NGeco Version: While the NG version you are viewing here features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics, we also sell the more affordable power2max NGeco ROTOR ALDHU Road Power Meter Crankset version.
Carbon NG Version: We also have the power2max NG ROTOR ALDHU Carbon Road Power Meter Crankset which features ROTOR carbon crank arms. This version is more expensive, but it is lighter and stiffer. Please note, the carbon version ONLY comes in a 30 mm spindle size.
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.
Chainrings: The power fits 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt 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.
The 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Shimano 12-speed 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 24 MM or 30 MM bottom brackets, depending on the version ordered. If you are ordering the same size as you currently have on your bike, you should be able to re-use your existing bottom bracket. However, if you are changing spindle sizes, you will need to replace your bottom bracket. Please contact us with questions, we are happy to help.
