Checking spoke tension
Warning
Danger of accidents
Incorrectly
tensioned
spokes
impair the
handling characteristic and
result in
secondary
damage.
The
spokes
break due to being
overloaded
if they are too tightly tensioned. If the tension
in
the
spokes
is too
low,
then lateral
and
radial
run-out will
form in the
wheel.
Other
spokes wil
l
become
looser as a result.
Check
spoke
tension
regularly, and
in particular
on a
new
vehicle.

Warning
Strike each spoke

Info
I
The
frequency
of the sound depends on
the
spoke length and spoke
diame-
ter.
If
you hear
different tone
frequencies
from different
spokes of
equal length
and
diameter,
this
is
an
indication
of
different
spoke
tensions.
I
You should
hear a high note.

If
the
spoke
tension
differs:
Correct
the
spoke
tension.
Check
the
spoke
torque.
