1. Open the tensioning lever by folding it by 180˚.
OPEN must now be visible.
2. Move the seat post into the right position.
3. Close the tensioning lever by swinging the lever by
180˚. CLOSE should now be visible. The lever should
be very easy to move from the beginning of the closing
movement up to halfway. Then, the force required to
move the lever must signicantly increase until the
lever is very dicult to move at the end.
4. a) If the quick-release skewer closes too easily, the
pre-tension must be increased: To do this, open the
tensioning lever and slide the seat post into the
desired position. Then, hold the tensioning lever and
turn the clamping nut on the opposite side clockwise.
Check whether the correct pre-tensioning has been
achieved by closing the tensioning lever.
b) If the quick-release skewer is too dicult to
close, the pre-tension must be reduced: To do this,
open the tensioning lever and slide the seat post
into the desired position. Then, hold the tensioning
lever and turn the clamping nut on the opposite
side counterclockwise. Check whether the correct
pre-tensioning has been achieved by closing the
tensioning lever.
5. Close the tensioning lever. The lever must be
positioned in such a way that it cannot be opened
accidentally.
6. Try to twist the saddle to check that it is rmly xed.
17.2 Lowerable seat post
Warning
Serious falls due to locked rear wheel.
▪ Before your rst ride, check whether the rear wheel
is locked by the lowering of the seat post. If the
saddle comes into contact with the rear wheel in its
lowest position, the insertion depth of the seat post
must be reduced. Make sure, however, that the seat
post is inserted at least 10 cm into the seat tube.
Information
If you want to retrot a lowerable seat post to your bi-
cycle at a later stage, it is possible that the tightening
torques for the seat post clamping screw(s) are lower
than the values given on the seat post clamp or in the
component operating instructions.

Lever
If your bicycle is tted with a lowerable seat post, you can
adjust the height of the seat post while riding. This is done
using the control element on the handlebars. Pressing the
lever either raises or lowers the seat post. Releasing the
lever locks the seat post in the corresponding position.
17.2.1 Positioning the control element
1. Loosen the screw on the control element by turning it
two to three turns anticlockwise.
2. Position the control element in the desired position.
3. Tighten the screw again by rotating it clockwise to
the specied torque using a torque wrench  13.

17.2.2 Changingtheleverpressure
If the lever is very dicult to press, it can make sense to
decrease the cable tension:
1. Turn the adjustment screw one or two turns
counterclockwise to decrease the tension.
If the lever is too easy to push and it is actuated too easily,
it can make sense to increase the tensile stress:
2. Turn the adjustment screw clockwise to increase the
tension.
17.3 Suspension seat post
Ask your cycle dealer to adjust the suspension elements
of the seat post.
