19.3 Grips
The grips must be held firmly with both hands
whilst driving and always held so that the ca-
bles and lines are oriented upwards.
Figure 17: Correct grip hold
The cables for the Rohloff hub gear are an
exception for this. If the handles are held cor-
rectly they point forwards into the direction of
travel.
Figure 18: Correct hold of the handle for the Rohloff
hub gear
Always hold onto the crank handles with
both hands while driving, braking, and
manoeuvring. If a driving situation requires you
to take one hand off the crank handle, make
sure the speed has been reduced to the mini-
mum possible beforehand.
19.4 Gear shift
19.4.1 Derailleur
With the derailleur, the gears can only be
changed while the crank is moving. Changing
the gear with the cranks stationary is not pos-
sible. In general, the torque applied to the
cranks should be reduced briefly while chang-
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 19: 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.
