Advice From Our Staff:
This is a more expensive power meter with the carbon crank arms, however at $790 you get dual-sided power and very lightweight and stiff carbon fiber crank arms. When compared to similar power meter cranksets, it’s a pretty nice value. If it’s in your budget, we highly recommend it.

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
Sigeyi AXO ROTOR Aluminum Version: We also have the Sigeyi AXO 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.
