Advice From Our Staff:
This is one of our finest power meters. To begin with, you have the power2max power meter spider which is a great unit. It measures power from both legs, is accurate and very reliable. You then add on the NG upgrade, which makes the power2max even better. To finish it off, you get the ROTOR ALDHU carbon crank arms which are ultra-light and stiff. This is an expensive power meter, but if it’s in your budget, it’s about as good as it gets!

- 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.

- 155 mm | 165 mm | 170 mm | 172.5 mm | 175 mm
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).
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.
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 Carbon Road Power Meter Crankset version.
Aluminum NG Version: We also have the power2max NG ROTOR ALDHU Road 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.
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 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 changing spindle sizes, you will need to replace your bottom bracket.
