3.1 Canviant de marxa
The PACTO EIGHT features a 6-speed Shimano derailleur system. Use the shifter on the handlebar to change gears. Shift to a lower gear for easier pedaling on inclines and a higher gear for faster speeds on flat terrain. Always pedal lightly while shifting for smoother transitions.
