8.5. Mounting the carbon seat post
Make sure your new carbon seat post match-
es the inside diameter of the seat tube of the
frame. The seat post must fit easily, without
pushing or twisting, and free of play into the
frame. A mismatch between frame and seat
post can cause failure of the seat post.
Do not use any grease!
Before the carbon seat post is inserted into the
seat tube, make sure the seat tube is abso-
lutely free of lubricants, sharp edges and
burrs. Clean the seat tube and remove burrs,
if necessary.
8.5.5 Mounting the saddle
Carbon seat posts are usually designed to
be combined with most sports saddles with
a saddle rail diameter of 7 mm. To mount
the saddle, release the fixing bolt/s by two
to three turns. You need not disassemble the
complete mechanism. In case the saddle rails
do not fit exactly into the clamp grooves, do
not try to force them in! The clamping mech-
anism or the saddle rail might break, thus
causing an accident or injury to the rider.
Retighten all bolts to the prescribed
torque after the first 100 - 300 km
and thereafter every 2,000 km. Improperly
tightened fixing bolt(s) may cause an acci-
dent.
Even a slight mismatch between seat
tube and carbon seat post diameter
or oil and grease in the seat tube, may lead
to a breakage of the seat post. This can
cause an accident or injury to the rider.

Maximum torque
of the seat tube clamping:
8 Nm
Minimum insertion depth:
LRS bikes

If in doubt, play safe and increase the inser-
tion depth of the seat post. An increased
insertion depth always means more safety.
