Notes:
Two methods for determining the speed of manual gear shifting:
One method: the logo on the hand change has 8-9-10-11, these are the speed of hand change.
Another method: install on the bicycle, and change gears during riding (or when the rear wheel is rotating) after debugging.
Do not operate the gear shift when the manual changer has not been installed, adjusted well, or the wheels have not rotated. This is an incorrect operation, which may damage the gearshift accuracy.
Due to the light and screen setting difference, the product's color may be slightly different from the pictures.
Please allow slight dimension difference due to different manual measurement.
