2. How An Internal Gear Hub Drivetrain Works
If your bicycle has an internal gear hub drivetrain, the gear changing mechanism will consist of:
– one, or sometimes two shifters
– one or two control cables~ one front sprocket called a chainring
– a drive chain
a. Shifting Internal Gear Hub Gears
Shifting with an internal gear hub drivetrain is simply a matter of moving the shifter to the
indicated position for the desired gear. After you have moved the shifter to the gear position
of your choice, ease the pressure on the pedals for an instant to allow the hub to complete the
shift.
b. Which Gear Should I Be In?
The numerically lowest gear (1) is for the steepest hills. The numerically largest gear
depending on the number of speeds of your hub, is for the greatest speed. Shifting from
an easier, “slower” gear (like 1) to a harder, “faster” gear (like 2 or 3) is called an upshift.
Shifting from a harder, “faster” gear to an easier, “slower” gear is called a downshift. It is not
necessary to shift gears in sequence. Instead, find the “starting gear” for the conditions
At first, practice shifting where there are no obstacles, hazards or other traf c, until you’ve
built up your con dence. Learn to anticipate the need to shift, and shift to a lower gear before
the hill gets too steep. If you have difficulties with shifting, the problem could be mechanical
adjustment. See your local bike mechanic for help.
c. What If It Won’t Shift Gears?
If moving the shift control one click repeatedly fails to result in a smooth shift to the next
gear chances are that the mechanism is out of adjustment. Take the bike to your local bike
mechanic to have it adjusted.
