SHIFTING SYSTEM
Function and operation
It uses a twist grip shifter to select the
desired gears. The chosen gear is indicated.
The IGH requires a momentary pause in the
application of pedal power.
Adjusting gears for internally geared hub
There are several methods used to adjust
gears for IGH and each hub is dierent. For
questions, see your dealer.
SHIMANO 8SPEED IGH
• Shift to the fourth gear.
• Now the two marks on the hub can be
brought into alignment. This is done by an
adjusting screw that the shifter cable runs
through. By turning the screw to the right
the markings move towards the front of
the bike while turning left moves the
markings towards the rear.
INTERNALLY GEARED HUB
One advantage of an internally geared hub
(IGH) is the encapsulated construction. The
technical mechanisms are almost completely
enclosed inside the hub. This prevents con
-
tamination from dirt and grime. The chain
on an IGH system lasts longer than on an
equivalent derailleur system. A disadvantage
is the slightly higher power losses within the
hub. IGH are sometimes used in combination
with a derailleur, freewheel and rim, roller or
integrated coaster brake.
Practice shifting in a trac free
area. Practice also using the
brakes. In road trac you may
be distracted from shifting and
braking by potential hazards.
DANGER!
