slightly snug.
IMPORTANT: Make sure
that (1) both sides of the front

ZULU THREE AND ZULU FOUR ASSEMBLY
Step 2: Attach Front Wheel
Locate the quick release
assembly. Remove the nut and
one of the springs.
Find the arrow indicating
direction of rotation on the
front tire. Lay the wheel on a
flat surface so that the arrow
indicates a counter-clockwise
rotation. Insert the quick release
skewer through the hub. Put the
spring and nut on the opposite
side of the hub. Keep the entire
assembly loose for now.
If this is the first time installing
the wheel on the bike, the brake
pads will have a black plastic
spacer between them. Remove
the black spacer. After the
spacer is removed, do not pull
the front brake lever until the
wheel is installed. If the front
brake lever is pulled without
a spacer or wheel in place
the brake pads can squeeze
together and will need to be
separated again before the
wheel can be installed.

FULLY insert the wheel assembly
into the dropouts at the bottom of
the front fork. The quick release
handle should be on the left
side of the bike (from the rider’s
perspective). Make sure that the
brake rotor slides between the
brake pads. If the brake pads are
compressed too close together,
gently push them apart using a
credit card, flat head screw driver
or a butter knife (But don’t use a
sharp knife!)
Tighten by turning the nut on
the right side of the skewer until
slightly snug.
IMPORTANT: Make sure
that (1) both sides of the front
axle are fully inserted into the
front dropouts and (2) the
nut on the right side and the
quick release washer on the
left side are FULLY SEATED
inside the raised lips on the
dropouts.
Tighten the quick release lever
completely by pushing it up
towards the fork. If the quick
release lever feels too tight or
too loose, adjust using the nut
on the right side of the axle.
