2) Shifting the Front Derailleur:
The front derailleur, which is controlled by the left shifter, shifts the chain between the larger and smaller chainrings. Shifting the chain onto a smaller chainring makes pedaling easier (a downshift).
Shifting to a larger chainring makes pedaling harder (an upshift).
b) Which gear should I be in?
The combination of largest rear, smallest front gears (Fig. 19) is
for the steepest hills. The smallest rear, largest front combination (Fig. 19) is for the greatest speed. It is not necessary to shift gears in sequence. Instead, find the “starting gear” which is right for your level of ability
