XCADEY XPOWER-S GEN2 ROTOR ALDHU Carbon Road Power Meter Crankset

The XCADEY XPOWER-S GEN2 ROTOR ALDHU Carbon Road Power Meter Crankset combines the XCADEY spider with the ultra-light ALDHU Carbon crankset. This XCADEY crankset measures power from both legs and is accurate to +/- 1.0%. The ALDHU Carbon Crankset weighs 100 grams less than the ALDHU aluminum model. In addition, it has increased vertical and horizontal stiffness by 11% and 36%, respectively. The power meter also features a rechargeable battery with 150 hours of ride time, active temperature compensation, and left and right leg power balance.

This power meter fits 30 MM bottom brackets and 110 BCD 4-bolt chainrings. See Compatibility tab for more information.

Power Measurement:

The XCADEY power meter measures power at the spider and is therefore able to measure power from both legs.

Dual-leg power measurement, lightweight carbon fiber crankset, accurate to +/- 1.0%, 150 hours of battery life, rechargeable battery, very lightweight, left/right power balance, ANT+ and Bluetooth compatibility, active temperature compensation. See Specs tab for more information.

Advice From Our Staff:

The XCADEY ROTOR ALDHU Carbon Road Power Meter Crankset is a more expensive power meter crankset because of the carbon crank arms, however you get dual-sided power and very light and stiff carbon fiber crank arms. We recommend this crankset to riders when it fits within their budget.


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 4-Bolt

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


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)

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

XCADEY ROTOR Aluminum Version: We also have the XCADEY XPOWER-S GEN2 ROTOR ALDHU Road Power Meter Crankset which uses ROTOR aluminum crank arms. This version is more affordable, but the aluminum crank arms are a bit heavier. ROTOR’s aluminum crank arms however are available in both 24 mm and 30 mm spindle sizes.


Chainrings: The power fits 110 BCD 4-bolt chainrings. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

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.
