nection to the handlebar stem. The outer rod
end is screwed completely into the rod and
secured with thread locker. Do not try to
turn this side of the rod end.
First make sure that the handlebar is aligned
perpendicular to the main frame tube. Identify
which wheel (or perhaps both wheels) needs
adjustments of the toe-in by measuring the
distance between rim wall and main tube on
the most forward point and on the most
backward point of the rim (value a
v
and a
h
in
the picture). The distances should be roughly
identical for one wheel.
Remove the bolt that connects the inner rod-
end to the handlebar stem, note the washer.
Caution! Do not move the rod-
end beyond its limits, or it will be de-
stroyed or get excessive play. Always hold
the rod end with a wrench or secure the
tie rod with a wrench against turning when
tightening the lock nut
Hold the rod-end with a wrench and loosen
the nut that is screwed against the rod-end.
Screw the rod-end into the tie-rod to enlarge
the distance b
v
between the front edges of the
front wheel. Screw the rod-end out of the tie-
rod to decrease the distance of the front
wheel edges.
Danger! The rod-end must be
screwed at least 8 mm into the tie-rod. If it
is screwed out to far, the thread could tear
out and the tricycle could become un-
steerable. This means that with a standard
length of the thread of the rod-end of 24
mm, a maximum of 11 mm visible free
thread length is allowed between rod-end
and lock-nut.
