Tighten carefully by approaching the
prescribed maximum torque value in
small steps (0.5 Nm increments) and
check in between the proper fit of the compo-
nent. Never exceed the maximum torque value
indicated by the manufacturer!

Children and adolescents need to have
the saddle height and the position of
saddle and handlebars checked at least
every three months!
Adjusting the height of the handlebars
The height of the handlebars compared to the saddle
and the distance between saddle and 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 stem systems that allow ver-
tical adjustment of the handlebars, i.e. the conven-
tional, the adjustable and the Aheadset
®
-stem.
These systems require special knowledge. In this
regard, the descriptions hereafter may be incom-
plete. If you are in doubt or if you have any questions,
contact your CENTURION dealer.

The stem
(a)
is one of the load bearing
parts of your CENTURION bike. Chang-
es to it can impair your safety. If you are
in doubt or if you have any questions, contact
your CENTURION dealer!
G
These routines require a certain amount
of manual skill and (special) tools. Ask
your CENTURION dealer to explain you
both function and adjustment of your stem or let
him do that work.
G
The bolted connections of stem and
handlebars have to be tightened to the
prescribed torque values. If you disre-
gard the prescribed values, the handlebars or
stem may come loose or break. Use a torque
wrench
(b)
and never exceed the maximum
torque values! You will find the prescribed values
in the chapter “Recommended torque settings”,
directly on the components and/or in the operat-
ing instructions of the component manufacturers
on this CENTURION CD-ROM.
G
Stems come in varying lengths
(c)
as
well as shaft and binder tube diameters
(d)
. A stem of inappropriate dimension
can become a source of danger: Handlebars or
stems can break, resulting 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 CENTURION
dealer will be pleased to help you.
A
Make sure the handlebar/stem com-
bination is approved by the handlebar
and/or stem manufacturer.

Make sure the handlebar clamping area
is free of sharp edges.
