Advice From Our Staff:
This is one of our finest track 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!
Options For This Power Meter
Crank arms: The ROTOR ALHDU Carbon arms use a 30 mm spindle and are available in the following sizes:
- 155 mm | 165 mm | 170 mm | 172.5 mm | 175 mm
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 Track Power Meter Crankset version.
Aluminum NG Version: We also have the power2max NG ROTOR ALDHU Track 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.
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: This power meter is compatible with 144 BCD 5-bolt track chainrings. Please also note, the power meter requires threaded chainring bolts.
Bottom Bracket: This power meter uses a 30 mm road spindle and must be used with a 30 mm bottom bracket.
IMPORTANT - Although this power meter is designed to be used on the track, it uses a ROTOR ALDHU/VEGAST road spindle and therefore requires the use of a road bottom bracket for proper fitment.

Common Questions and Answers

- Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.
