Product Highlights
Fast, High Accurate Shifting
High-precision transmission structure design Optimized motor control algorithms 100000+ front and rear motor tuning Front derailleur responses in 0.3 seconds Rear derailleur responses in 0.09 seconds
Smooth Shifting Experience
Sequential Shifting Compensation Shifting By presetting, you can simply adjust the rear derailleur to the trigger gear, and both the front and rear derailleurs will automatically adjust to progressively increase the gear ratio between the chainring and the freewheel.Similarly, with the compensation shifting function, you only need to adjust the front derailleur when shifting up or down, and the rear derailleur will automatically adjust accordingly.
Buttons For More Customizability
Customizable X, Y, and Z buttons function setting to achieve bike computer page-turning, lap counting, light switching, and bike light mode changing... more personalized!
