To shi� with a derailleur
A derailleur moves your chain from one
gear to another. You shi� gears by chang-
ing the posi�on of a shi� lever (also called
a shi�er), which controls the derailleur. On
most bicycles the le� shi�er controls the
front derailleur and the right shi�er
controls the rear derailleur.
Shi� gears only when the pedals and chain
are moving forward.
Decrease the force on the pedals as you shi�
gears. Reduced chain tension helps the chain
shi� gears quickly and smoothly, which
decreases chain, derailleur, and gear wear.
Use only one shi�er at a �me.
Do not shi� gears when you ride over bumps
to prevent dropping or jamming the chain or
missing a gear.
Do not ride with the chain in the cross-over"
posi�on. Cross-over is when you shi� the
derailleur so the chain crosses from the
biggest front sprocket to the biggest rear
sprocket. (also the smallest sprocket to the
smallest sprocket).
In this posi�on, the chain is placed at an
extreme angle causing the chain and gears to
run roughly, and the parts to wear at a faster
rate(Figure 1.13).
Check the brake pads for wear.
Disc brakes: Replace brake pads that are
thinner than 1mm.
Disc brake rotors: Check the thickness/wear
of the rotor. The minimum thickness is o�en
printed on the disc.
Check brake pads every 4 month or replace
once the brake force is significantly reduced.
Important! Different types of disc brakes
may require specific adjustments not
covered in this sec�on.If you are unsure of
what needs to be done see a qualified
bicycle mechanic.
Misalignment of the disc brake may be due
to the following:
·The wheel is not centered.
·The caliper body is misaligned.
·The brake pads are not centered.
Rotate the wheel and look at the gap
between the rim andfork. lf the gap is
uneven, loosen the axle nuts and adjustun-
�l the wheel and disc rotor are centered.
Brakes
Adjus�ng the Disc Brake
Center the wheel
Improper derailleur shi�ing technique could cause
your chain to jam or come off, causing you to lose
control and fall.
SPECIAL NOTES FOR E-BIKE
WARNING!
Disc brakes are sharp, keep fingers away from the
brakecaliper and rotor. If fingers contact the disc
brake while thewheel is turning serious injury may
occur.
WARNING!
Since some e-bikes have thro�le mode, users may
shi� gears when sliding which is wrong.
WARNING!
Center the Brake Pads
lnsert a 1/32" spacer gage between the
disc rotor andbrake pad.
lnsert a 1/32" spacer gage between the
disc rotor andbrake pad.
Using a 5 mm Allen wrench, turn the brake
pad adjustment screw to move the brake
pad.Turning the pad clockwise moves it
towards the disc rotor, counterclockwise
moves the pad away from the disc rotor.
Adjust the pad un�l the gap between the
disc rotor and the brake pads are even
(1/32" per side).
Re-�ghten the set screw.
Realign the Caliper Body
Using a 5 mm Allen wrench, loosen the two
centering adjustment screws. Adjust the
caliper body un�l the gap between the disc
rotor and the brake pads in the caliper
bodyis even (1/32" per side).
Tighten the centering adjustment screws.
lf the brake cable wire is not a�ached to
the brake arm then loosen the cable anchor
bolt un�l you can see a gap large enough
for the brake cable wire.
Pull on the brake cable wire and place it
under the cable anchor bolt.
Tighten the cable anchor bolt. Note: The
brake cable should not be "pulling" on the
brake arm.
