To open the quick-release device, proceed as follows:
› Throw back the quick-release lever so that its inner
face or the lettering OPEN is visible.
› Open the quick-release device as far as possible.
› Turn the adjusting nut anticlockwise to further
slacken the quick-release device.
To close the quick-release device, proceed as follows:
› Adjust the clamping strength by turning the adjust-
ing nut.
› If the quick-release device closes too easily, open
it again and turn the adjusting nut clockwise.
› If the quick-release device still closes too easily,
repeat the previous step.
› If the quick-release device is too difficult to close,
turn the adjusting nut anticlockwise.
› Turn back the quick-release lever from the OPEN

› When closed, quick-release levers must lie flat
against the frame, fork and saddle clamp. Make
sure that quick-release devices for the hubs point
backwards when closed as otherwise they could
snag on obstructions when the bike is moving
and open. This could lead to serious accidents.

9.2.3 Determining the correct saddle height

› Sit on the bike saddle.
› Try to reach the pedal with your heel when it is in
the bottom position. Your knee should be more or
less fully straightened out.
› Place the balls of your feet on the centre of the
pedal. If your knee is now slightly bent, the saddle
height is correct.
Never tighten the seatpost if the maximum mark or
stop mark is above the top of the seat tube as other-
wise you could injure yourself or damage the seat-
post. Always observe the specified tightening torques.
In full-suspension mountain bikes the seat tube is also
open at the bottom, so the seatpost should only be insert-
ed a certain distance downwards to ensure the rear swing
arm and suspension element never come into contact
when the bike is in use.
