Adjusting The Height Of The Handlebars - BMW Mountain Bike Enduro Owner's Manual

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. A bicycle
specialist shop of your trust has a very wide range of saddles
available and can offer advice on position (a).
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 (b).

11.2 Adjusting the Height of the
Handlebars.
The height of the handlebars determines how much your upper body will
be inclined forward. Lowering the handlebars gives you a streamlined
position and brings more weight to bear on the front wheel. However, it
also entails an extremely forward leaning posture which is tiring and less
comfortable, because it increases the strain on your wrists, arms, back,
upper body and neck.
There are three different systems that allow vertical adjustment of the
handlebars, i.e. conventional, adjustable and Aheadset
systems require special knowledge. In this regard, the descriptions
hereafter may be incomplete. If you have the slightest doubt, ask your
BMW partner for help.
(c)
The stem is one of the load bearing parts of your bicycle.
Changes to it can impair your safety. If you are in doubt or if you
have any questions, please contact your BMW partner!
Stems come in varying lengths as well as shaft and binder
tube diameters (d). If you opt for a stem of inappropriate siz-
ing, handlebars and stem may break and result in an accident.
When replacing any parts be sure to only use parts that bear
the appropriate mark and, to be on the safe side, original spare
parts. Your BMW partner will be pleased to order the respective
original spare parts for you!
