Never apply grease or oil into a seat
tube of a frame made of carbon unless
an alloy sleeve is inside the frame. If you
mount a carbon seat post, do not put any grease
on it, even if the frame is made of metal. Once
greased, carbon components may never again
ensure reliable clamping! Use special carbon as-
sembly paste instead
(a)
.
G
Make sure not to overtighten the binder
bolt of the seat post clamp. Otherwise
you may damage the seat post or the
frame. Risk of an accident!
G
Never ride your bike 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. In the case
of frames with seat tubes that extend beyond the
top of the frame’s top tube the seat post should
be inserted into the seat tube at least below the
bottom of the top tube and below the top of the
rear stays! If seat post and frame require different
minimum insertion depths, you should opt for the
deeper insertion depth.
A
If the seat post does not move easily in-
side the seat tube or if it cannot be tight-
ened sufficiently, ask your CENTURION
dealer for advice. Do not use brute force!
A
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!
Adjusting the height of the handlebars
In principle, CENTURION road bikes are sports bikes
designed for speed. For this reason alone riding a
CENTURION road bike requires certain basic pre-
conditions of the trunk, shoulder and neck muscles.
The height of the handlebars compared to the saddle
and the distance between saddle and handlebars
determines how much your upper body will be in-
clined forward. Lowering the handlebars gives you a
streamlined position and brings more weight to bear
on the front wheel. However, it also entails an ex-
tremely forward leaning posture which is tiring and
less comfortable, because it increases the strain on
your wrists, arms, back, upper body and neck. As a
general rule you should be able to grip all three basic
positions of the handlebars
(b-d)
without any dis-
comfort on a road bike.
In the case of road bikes an Aheadset
®
-stem allows
the vertical adjustment of the handlebars. This ad-
justment requires special knowledge. In this regard,
the descriptions hereafter may be incomplete. If you
are in doubt or if you have any questions, contact
your CENTURION dealer.
