q Checking Spoke Tension
1
Verify the spoke tension by grasping and shaking each spoke.
Spoke should not be loose from hub. Look for any play between the
spoke flanges where it mates with the hub. Try to turn the nipple
using your fingers. You should not be able to spin any nipple by hand.
If one or more spokes is loose, all spokes should be checked and
tightened with a spoke wrench if needed.
2 Start with spoke closest to the
tire valve stem and tighten each
nipple, in sequence, exactly 1/4
to 1/2 turn. A single 1/4 to 1/2
turn may not be enough to bring
the spokes into proper tension.
Continue tightening all spokes no
more than 1/2 turn in sequence
until all spokes are tight.
Note: More than a 1/2 turn each
can cause the wheel to become
distorted and wobbly thus perma-
nently damaging the wheel.
