– if this is so, you’ve reached the correct
saddle height.
• Check that you can stay in the saddle and
still reach the ground with your tiptoes. If
this isn’t the case, put the saddle a little
lower.
• Memorize the insertion mark on the
seatpost so that when later unfolding you
immediately know the correct height of the
seatpost.
BIRDY STEMS
Two dierent handlebar stems are available
for the Birdy:
• Sport stem, adjustable – allows sporty posi-
tion for riders of all sizes
• Comfort stem, adjustable – the handlebar
is closer to the saddle and allows a more
upright rider position
Your dealer can change the stem following
your needs.
Upright rider’s position
Advantage: lower load on the wrists, arms
and cervical spine.
Disadvantage: higher load on the saddle.
Sporty rider’s position
Advantage: less loads for the seating area,
more ecient performance, less air resist-
ance, more weight on the front wheel.
Disadvantage: higher loads for the wrists,
arms and cervical spine.
Do not ride if the seatpost is
withdrawn beyond the ‘MINI-
MUM INSERTION’ mark! This
mark must not be visible: if it
is, the seatpost could break or
the frame could be damaged.
The seatpost is not designed for
mounting bags or carriers on
the seatpost or the saddle. This
could overload of the seatpost!
DANGER!
