Care and maintenance of
Carbon fiber seat Posts
inserting the seat Post
Check the seat tube (1) opening , and slot (2) carefully
for sharp edges or burrs. Anything that can scratch,
score, gouge, or cut the seat post can cause serious
damage leading to breakage of the seat post.
Sharp edges or burrs can be removed by hand by
lightly sanding with a very fine sandpaper (400 grit).
The should feel very smooth without jagged edges
or nicks.
Figure 32.
1. Make sure the seat post, seat binder, and seat
tube are clean.
2. apply small amount of a carbon seat post
gel (Cannondale part number KF115/ to
seat post surface. the gel adds desirable
friction and minimizes corossion. it will
help keep your seat post in place.
3 Position the seat binder on the seat tube with
the binder slot (A) opposite the seat tube slot
(b). Locating the binder slot opposite the seat
tube slot reduces the chances of cracking from
deformation or accidental overtightening.
4. Insert the seat post and tighten the seat binder
to the specified torque with an accurate torque
wrench. Consult the seat post manufacturer’s
instructions for torque information.
5. Check tightening torques of the saddle to seat
post clamp bolts. Too much torque may break the
bolts. Too little torque will result in movement
which leads to fatigue and bolt breakage.

Periodic seat Post inspection
Frequent seat post checks are necessary to identify
the problems that can lead to an accident. Regularly
or in conjunction with your regular bike maintenance
routine, do the following:
1. Remove the seat binder from the frame seat
post. Clean the binder, the seat post, and inside
the seat tube. Use a clean dry towel. Do not use
solvents.
2 Carefully inspect the seat post for damage (e.g.,
cracks, scratches, scrapes, gouges, splintering).
If the seat post is damaged in any way, (cracks,
scratches, scrapes, gouges, splintering), do not
ride it; discard it. Replace it with a new one.
3. Always properly torque saddle to seat post clamp
bolts. Too much torque may break the bolts.
Too little torque will result in movement which
leads to fatigue and bolt breakage.
