Operating instructions
Adjusting the correct saddle height
To adjust the saddle height loosen the binder bolt (a)
or quick-release lever (read the chapter “How to use
quick-releases of seat post clamps“ beforehand).
Release the seat post binder bolt by using a suitable
tool and turn it anticlockwise by two to three turns or
open the quick-release at your saddle clamping.
You can now adjust the AX-Lightness and engage
seat post to the desired height.
Do not pull out the seat post too far from the seat tube
and do not slide it in too deep
(b). The binder clamp
of AX-Lightness seat posts should be positioned in
the area which is reinforced with the UD-fabric (UD
= unidirectional)
(c), the binder clamp of engage seat
posts in the area marked with the scale
(d). The mark
indicating the minimum insertion depth (min. insert)
on the seat post rear serves you as additional refer-
ence point.
a
In the case of frames with long seat tubes
which continue above the top tube, the
seat post should at least reach below the
height of the top tube or the rear stay! This
can mean a minimum insertion length of 10
centimetres (3.94 in.) or more.
Retighten the seat post in its new position. To do so
turn the seat post binder bolt clockwise or close the
quick-release lever (read the chapter “How to use
quick-releases of seat post clamps“ beforehand).
You should not need high hand forces to tighten the
bolts or the quick-release to achieve a suitable clamp-
ing eect. Otherwise the seat post does not match
the frame.
Check the tight t of the seat post by taking hold of
the saddle at both ends and then trying to rotate the
seat post inside the seat tube
(e). If it does rotate, gen-
tly retighten the binder bolt or the quick-release and
check the seat again. Do not exceed the prescribed
torque values.
If the seat post is still not tight, check whether the bolt
is tightened to the prescribed torque value
(f). If you
are in doubt about the proper torque value, read the
operating instruction of the frame manufacturer or
ask your AX-Lightness and engage dealer for advice.
If in spite of observing the indicated torque values
the seat post clamping is still not tight, release the
bolt and remove the seat post. Apply a new layer of
AX-Lightness and engage carbon assembly paste
(g)
on both clamping areas. Retighten the bolt to the
recommended torque value
(h). If the seat post is still
not tight, ask your AX-Lightness and engage dealer
for advice.
a
Do not grease the seat tube of a frame.
Once greased carbon bre may never ever
be xed in a secure and safe way again!
g
Do not overtighten the binder bolt or the
quick-release of the seat post clamp. Over-
tightening can damage the AX-Lightness
and engage seat post and/or frame, and
result in an accident and injury of the rider.
