B. Adfustrnent,
Trouble Shooting
and Maintenance
When
replacing
the
wheels, they
should be carefully
centered
between
the
forks and
brakes. Be
certain
that
wheel
nuts are
replaced while
all spokes
should
be adequately
tightened.
When
the
gear
shift
operating
cable connector is
re-
assemblcd, recheck
its setting
as described
in
Sec.
6.3.1 3.
Wheels
should be
regularly
checked
for
"wobbling"
from
side
to side, and
"hop"-
being out of
round
or
of
unequal diameters.This misalignment
can
be
detected bcst
by turning the
bicycle
upside down,
rotating
the
wheel while
using our
finger
or
a
pencil placed
next
to
the rim as
a
guide.
Severe
misalign-
ment will
causc the tire
to
intermittently
rub
against the fork,
or
the rim against
the
brake shoe.
Warning: Whccl
misalignment
will lead
to
grabbing
or failure of braking
power,
and
should be
corrected
at
once.
To
correct this
problem,
first
check the
rim
to make sure it is
not dented or
twisted. lf it is, take
the
wheel
to a
dealer for
specialized repair or
replacement.
Uneven spoke tension,
or
missing, bent
or
broken spokes,
will
also cause
the
