internal gear hub that meets and
exceeds all these requirements!

quality design.
i-MOTION 3 gear hub
Load shiftable. Light shifting
forces. Shifting during stand-
still is possible: Easy re-start
e.g. at a traffic light.
i-MOTION 3 connecting link
Easy wheel removal:
The gear adjustment remains
unchanged.

OPERATION
SHIFTING
1Shift gears by turning the
rotating grip.
» You can shift while standing still
or while riding your bicycle.
» When approaching inclines shift
down in good time.
» The smoothest and fastest gear
change happens when changing
gears while pedaling with low
force.
BRAKING
On long and steep downhill roads,
simultaneously use rear and front
brakes to avoid heating up of the
brakes.
Excessive heating of the hub
with the back pedal brake
may result in loss of lubricant and
braking too hard. This will lead to a
trip to the repair shop.
Read the applicable user
manual for each bicycle
equipped with i-BRAKE or band
brakes.

MAINTENANCE AND CARE
GEAR ADJUSTMENT
2Shift the twist shifter to the
3rd gear.
The shift cable must be with-
out play in 3rd gear. That
means it must be pulled out of the
hub as far as it will go.
3While pulling the plastic re-
tainer (1), it should not be pos-
sible to pull the shift cable further
out of the hub.
– Shift cable has too much play:
Shift the twist shifter to the 1st
gear.
4Reduce play of the shift
cable by turning the barrel
adjuster (2) at the shifter.
– Shift cable is too taut:
The shifter won‘t shift into 3rd
gear or the hub doesn‘t shift in
1st gear or will permanently
switch between 1st and 2nd
gear.
Shift the twist shifter to the 1st
gear.
4Decrease shift cable ten-
sion by turning the barrel
adjuster (2) at the shifter.
» Shift the twist shifter to the 3rd
gear and check again, until there
isn‘t any play in the shift cable.

CLEANING
» Your SRAM i-MOTION 3 compo-
nents are well protected from
external evironmental impacts.
However, do not use water under
pressure (such as pressure wash-
ers or water jets) for cleaning to
prevent malfunctions due to water
penetration.
» During the winter season, you
should clean your bicycle in
shorter intervals so that winter
road salt cannot cause any dam-
age.
» Do not use agressive cleaners.
» Clean dirty chains before oiling.
Let cleaner set for only a few
minutes and rinse with water. Do
not oil chain until completely dry.
LUBRICATION
» The rear wheel hub is provided
with permanent lubrication and
maintenance-free under normal
conditions.
» Regular lubrication will extend the
chain's service life.

REPAIR WORK
Only a qualified bike dealer
should perform any necessary
work on the gear hub, shifter, and
brakes.
» Unauthorized work on your
i-MOTION 3 system could endan-
ger you and your warranty may
become void.
» Please contact your qualified bike
dealer regarding any questions or
problem you may have.
Back pedal brake
If the back pedal brake is braking
too hard, the brake jacket has to be
lubricated with special grease. This
work must be performed by a quali-
fied bike dealer.
Cable Change
If a cable must be replaced (shifter
cable or brake cable), contact your
qualified dealer.
WEAR PARTS
Brake liners or brake jackets, brake
cables, shift cables, handlebar
grips, sprockets, and bike chains
are wear parts. Please check these
parts regularly and replace them
timely.

26 Align the shifter on the han-
dlebar grip and position the

Never use lubricants or sol-
vents to install handlebar
grips. Handlebar grips provide an
axial safety function and may not
become separated from the hand-
lebar.
» Make sure that the shifter and
brake lever function properly and
are unobstructed (re-adjust if
needed).
» Never ride without the handlebar
grips. The turning grip of the twist
shifter could become loose. This
can result in severe injury.
