est sprocket, cautiously move the derail-
leur with your hand in the direction of the
spokes while rotating the rear wheel.
• If the idler pulley touches the spokes or the
chain begins to climb over the sprocket,
you should limit the pivot area. Turn the “L”
marked screw until the derailleur reliably
stops at the appropriate point.
• Now look at the position of the derailleur
cage relative to the cassette. There should
be space between the upper idler pulley
and the largest sprocket.
• The derailleur has a screw (A) to adjust this
distance on the front side of the dropout
• For the Birdy, screw this out as far as it will
go. The derailleur must be in its forward
most position.
THE CHAIN TENSIONER
The chain tensioner keeps the chain under
tension during the whole folding process.
The chain tensioner is mounted on the lower
derailleur jockey wheel, replacing its bolt
with a longer one. The bolt is secured on the
other side with a nut.
The adjustment of the front
derailleur is very sensitive.
Incorrect adjustment can cause
the chain to come off possibly
resulting in an accident. The ad-
justment of the front derailleur
is a matter for the professional
in the workshop.
DANGER!
TIP!
If you replace the rear derailleur,
check that the new one has the same
cage length as the old one. Otherwi-
se problems can arise during folding,
as it can’t be guaranteed that the
chain will remain under tension.
ATTENTION!
The adjustment of the rear derail-
leur is dicult and should be left
to an experienced mechanic. In-
correct settings can cause serious
mechanical damage. If you have
problems with the system, please
contact your dealer.
