Operation Manual
Be sure not to pull out the seat post too far – the mark on the seat post
(max., min., stop or the like) should always remain within the seat tube
– and to grease the surface of an aluminium or titanium seat post that is
inserted into a seat tube made of aluminium, titanium or steel. Do not grease
carbon seat posts and/or carbon seat tubes in the clamping area! Use spe-
cial XLC assembly paste instead .
Do not use brute force, if the seat post does not move easily
inside the seat tube or if it cannot be tightened sufficiently, ask
your bicycle dealer for advice!
The minimum insertion depths marked on seat post and frame
may differ. Be sure to insert the seat post to the deepest inser-
tion depth.
Align the saddle with the frame by using the saddle nose and the bottom
bracket or top tube as a reference point.
Clamp the seat post tight again by closing the quick-release , as de-
scribed in chapter or by
turning the seat post binder bolts clockwise in half turns. You should not
need much strength in your hands to clamp the seat post sufficiently tight.
Otherwise the seat post does not match the frame.
Verify in between that the seat clamp is sufficiently tight by taking hold of the
saddle at both ends and then trying to rotate the seat post inside the seat
tube . If it does rotate, gently retighten the clamping bolt by half a turn
and do the check again.
Never apply grease or oil into a seat tube of a frame made of
carbon, unless an aluminium sleeve is inside the frame. If you
mount a carbon seat post, do not put any grease on it, even if
the frame is made of metal. Once greased, carbon parts may
never again ensure reliable clamping.
Tighten carefully by approaching the prescribed maximum
torque in small steps (0.5 Nm increments) whilst constantly
checking the proper fit of the component. Never exceed the
maximum tightening torque indicated by the manufacturer!
Do not overtighten the binder bolt of the seat post clamp. Oth-
erwise the seat post or the frame can be damaged. Risk of an
accident!
Does the leg stretch test now produce the right result? Check by moving
your foot and pedal to the lowest point. When the ball of your foot is exactly
above the pedal centre in the ideal pedalling position, your knee should be
slightly bent. If it is, you have adjusted the saddle height correctly. Check
whether you can touch the ground safely while sitting on the saddle by
stretching your feet to the floor. If you cannot, you should lower the saddle
a little, at least to begin with.

Never ride your bicycle with the seat post drawn out beyond
the limit, maximum, or stop mark! The seat post might break or
cause severe damage to the frame. If your bicycle has a long
seat tube continuing beyond the top tube, the seat post should
at least reach below the level of the top tube and the tip of the
rear stays!
If sitting on the saddle causes you trouble, e.g. because it
numbs your crotch, this may be due to the saddle. Your bicycle
dealer has a very wide range of saddles available and can offer
advice on position .
With full-suspension mountain bikes the seat post should not
project from the seat tube at lowest saddle height, as other-
wise the rear shock arm may collide with the seat post during
compression.
Integrated seat posts have to be shortened to adjust them to the individual
needs of the cyclist. The seat post clamping itself provides only limited verti-
cal adjustment.
Shortening the seat post is a very delicate job, best left to your
bicycle dealer! An improperly shortened seat post may result in
damage to the seat post! Risk of an accident!
In case you nevertheless want to shorten the integrated seat post by your-
self, you need special tools!
Determine the desired saddle height . Keep in mind that another saddle
or pedal model may have a significant influence on the length of the seat
tube!
Please note that shortening the seat post is an irreversible ad-
justment. Therefore, ask your bicycle dealer to do this job.
Use a marker pen to indicate the length you want to shorten. Slide an ap-
propriate saw capture on the seat tube until the line of the marker is visible
in the saw capture slot.
Use a saw with a metal cut saw blade. To avoid any damage to
the carbon tube, be sure to use a 24 teeth per inch saw blade.
Saw the tube, remove the saw capture and deburr the cutting edges with
sandpaper.
Mount the saddle clamp and slide it as deep as possible . Finish by fixing
the saddle with a torque wrench according to the indications on the compo-
nent and/or in the enclosed manual. The usage of XLC-mounting paste
will help you to avoid overtightening.
