Stems come in varying lengths (e) as
well as shaft and binder tube diameters.
A stem of inappropriate dimension can
become a source of danger: Handlebars or stems
can break, resulting in an accident. When replac-
ing 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.
G
The stem 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
The bolted connections of stem and
handlebars have to be tightened to the
prescribed torque values (f) . If you dis-
regard the prescribed values, the handlebars or
stem may come loose or break. Use a torque
wrench and never exceed the maximum torque
values! You will find the prescribed values in the
chapter “Recommended torque settings”, direct-
ly on the components and/or in the operating
instructions of the component manufacturers on
this CENTURION CD-ROM.
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.
A
Make sure the handlebar/stem com-
bination is approved by the handlebar
and/or stem manufacturer.
A
Make sure the handlebar clamping area
is free of sharp edges.
Stems for threadless systems, the
Aheadset ® - system
In the case of CENTURION bikes with Aheadset
®
headsets the stem also serves to adjust the bearing
preload. If you change the position of the stem you
have to readjust the bearing play (see the chapter
“The headset” and the instructions of the component
manufacturers on this CENTURION CD-ROM).
The vertical setting range is determined by the in-
termediate rings, also referred to as spacers
(g)
. In
the case of flip-flop stem models the stem can be
mounted the other way round to achieve a different
handlebar height.
Unscrew the bolt at the top of the fork steerer tube
which serves to adjust the initial bearing pressure, re-
move the Ahead cap and release the bolts on either
side of the stem by up to three turns
(h)
. Remove the
stem and spacers from the fork steerer tube. In doing
so keep hold of both frame and fork to prevent the
fork from slipping off the head tube.
