ing the gear so that the gear change can hap-
pen more quickly.
The gearshift control elements are normally
designed so that they can be operated using
thumb / index finger shift control (for mechani-
cal gear systems) or buttons (for electronic Di2
gear systems). With the cassette at the bottom,
switching to the next largest sprocket means a
lower or easier gear and to the next smallest
sprocket a larger or more difficult gear.
Figure 11: Cassette
With the
thumb / index finger shift control
,
gear changes are achieved by:
"Thumb shifter" – operation by pressing in
the direction of travel with the thumb
“Index finger shifter” – operation by pulling
in the opposite direction of travel with the
index finger or using the thumb to press
against the direction of travel.
The mechanical gearshifts do not provide a
display for the gear selected. There is only an
orientation as to which sprocket is currently
being used via a display above the handle.
In electronic Di2 gearshift, you can shift up or
down by pressing the
button
.
On an electronic Di2 gearshift, gear changes
are achieved by:
Pressing the small button with your thumb
to shift up.
Pressing the large button with your thumb
to shift down.
Figure 12: Buttons for shifting up and down
On an electronic gearshift with buttons, the
current gear is shown on the gearshift display.

It is also possible to operate the gearshift by
shifting gears with your chin
. One of the two
buttons
of the Di2 button on the left in the
direction of travel can be pressed to shift up;
one of the two buttons of the Di2 button on the
right in the direction of travel can be pressed to
shift down. The current gear is always shown
in the gearshift display.
