Sigeyi ROTOR ALDHU Road Power Meter Crankset

Sigeyi ROTOR ALDHU Road Power Meter Crankset

The Sigeyi 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.
