Does the Sigeyi power meter work with Shimano 12-speed road chainrings?

Yes, all Sigeyi 4-bolt road power meters are compatible with Shimano Ultegra 8100 chainrings and Shimano DURA-ACE 9200 chainrings. In addition, if you are looking to replace your Shimano road crankset with a Sigeyi, we would recommend the Sigeyi ROTOR ALDHU Road Power Meter Crankset.

Sigeyi ROTOR ALDHU Road Power Meter Crankset

For Shimano users, this Sigeyi crankset serves as a direct replacement. If you select one of the 24MM ALDHU crank sizes, it will come with the same spindle size as your current Shimano crankset and will fit your bottom bracket without any changes. In addition, if you select the 110 4-Bolt BCD option, you can also use your current 12-speed Shimano chainrings on it. This makes replacing your Shimano crankset very simple and easy. Additionally, it’s accurate to within +/- 1.0%, measures power from both legs and is very affordable for this type of power meter crankset.
