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 use brute force, if the seat post does not move easily
inside the seat tube or if it cannot be tightened sufficiently, ask
your BMW partner 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 (b+c), as
described in chapter "How to Use Quick Releases and Thru Axles"
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
(a)
of the saddle at both ends and then trying to rotate the seat post inside
the seat tube (d). If it does rotate, gently retighten the clamping bolt by
half a turn and do the check again.
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.
Otherwise the seat post or the frame can be damaged. Risk of
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 cor-
rectly. 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.
