USING THE TELESCOPIC SEATPOST
For normal daily folding it is easiest to lower the main seatpost tube and
to leave the upper post (fig. 2) clamped in it's extended, riding position:
the upper post and saddle would only be lowered when maximum
compactness is needed. Generally it is easier to raise and lower the upper
post when the main post is up (if you try and move it with the main post
down, you may also have to release the clamp on the mainframe).
If you remove the upper post for any reason, on re-assembly, take care not
to damage the plastic sleeve in the main seatpost tube.
Do not extend the upper post further than the maximum height mark, in
the highest position this should not be visible above the top of the plastic
sleeve. If the maximum height mark is visible the post is set too high. This
could cause damage to the seatpost or frame in use; do not attempt to
ride the bike with the upper post in this position, doing so will invalidate
your warranty.
Before fitting the new seatpost you will need to remove the existing post.
With the bike unfolded, remove the saddle and pentaclip from the top of
the seatpost (fig. 1), along with the rubber o-rings if fitted. Take a note
of the saddle angle and fore-aft position before removing the saddle
from the seatpost. Undo the seatclamp on the main frame and allow the
seatpost to drop down through the main frame.
The new telescopic post is supplied unassembled (fig. 2) with the
exception of the seatclamp assembly (fig. 3) which has the quick release,
clamp band and barrel nut pre-assembled.
