Tracking adjustment
The rear wheels of the Trets are mounted on axles that do not stand parallel to
the road surface; this makes tracking adjustment essential for keeping tire wear
to a minimum. To adjust the tracking on your Trets, proceed as follows:
• Assemble the Weber coupling on the host bicycle as described on the
following page • Hitch the Trets onto the host bicycle • There are two 8 mm
clamping screws on the front of the boom where the tow-bar is inserted. These
screws must be loosened, but only drawn so far out that the tow-bar can be
turned and raised without it slipping back down again • Now adjust the length
by placing a meter stick vertically on the ground beside the quick release lever
on the Trets main frame tube. As shown in the photograph below, the distance
between quick release and ground must measure 250 mm • When the correct
position has been found, tighten the clamping screws on the main tube.

Length adjustment
The Trets can be adjusted in length by
170 mm without the chain having to
be shortened. To make this
adjustment, open the quick release
lever on the left-hand side of the
Trets. Now you can adjust the length
of the Trets by sliding the boom up
and down within the frame tube as
required. When you have adjusted
the boom to the desired length, the
quick release lever must be closed
again.
Caution: The quick release must be closed firmly when adjustment has
been completed. If it is not firmly closed, there is a danger of accidents
or damage to the frame.
When length has been adjusted, height must be adjusted accordingly
