Sigeyi AXO ROTOR ALDHU Road Power Meter Crankset
The Sigeyi AXO ROTOR ALDHU Road Power Meter Crankset combines the Sigeyi spider with an ALDHU crankset. This Sigeyi crankset measures power from both legs, is accurate to +/- 1.0% and is lightweight. The power meter also features a rechargeable battery with 300 hours of ride time, auto-zero functionality, and left and right leg power balance.
If you currently have a Shimano road crankset on your bike, this power meter is a direct replacement. This means it will fit your current Shimano bottom bracket and you can also use your current Shimano chainrings on it. This makes installation and set-up very easy.[/vc_column_text][/vc_column][/vc_row]

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 Carbon Version: We also sell the Sigeyi AXO 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.
Compatibility
Chainrings: The power fits 110 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.
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.
Note - The Sigeyi AXO ROTOR Road Power Meter is not compatible with ENVE Melee and Trek bikes that have a T47 bottom bracket.
