Attention!
When you move the
front boom take care that its end does not
damage any cables or wires that possibly
come out of the main frame (e.g. light ca-
bles or wires from the drive train). Please
inform yourself about the length of the
front boom on your tricycle before you do
any work. While moving the front boom
you also have to move the light cables. The
light cable must never be stressed by pull-
ing.
For riders with short leg length the front
boom has to be cut by a bicycle mechanic, so
it can be inserted maximum possible. It is im-
portant to trim the end of the tube neatly.
The bare metal of the shortened tube end has
to be protected against corrosion with a paint
stick or wax spray.
The maximum insertion of the front boom is
limited by possible heel cycle of the frame’s
cross bar, depending on the rider’s shoe size.
Please check before riding your tricycle that
there is enough heel clearance. For shorter
riders under 175 cm body height we recom-
mend to use shorter cranks.
In order to align the front boom, you can look
beyond the bottom bracket shell at the rear
wheel axle and align the front boom parallel
to it. Align your eyes with the bottom bracket
axle and not the front derailleur tube. Then
sit down on your tricycle and check the posi-
tion.
On the left underside of the front boom,
some models have a fine line. Align this line
with the sticker on the main tube’s front end
right above the clamping bolts to adjust the
bottom bracket axle to a horizontal position.

Attention!
The minimum inser-
tion depth of the front boom into the main
frame is 8 cm (3,1"). The end of the front
boom must not be visible in the clamping
slot when you look at the main frame from
below, since this may result in a damage of
the frame.
The rear end of the front boon must never be visible in
the clamping slot.
Tighten the bolts alternating in several steps
with a torque wrench (tightening torque 1

Nm). On your first ride check whether
there is sufficient clamping. Otherwise there is
a risk that a single screw is overloaded and
the frame gets damaged.
