Adjusting The Height Of The Handlebars - Centurion Backfire E 640.27 Translation Of The Original Operating Instructions

When riding steep downhill courses on
G
your mountain bike pedelec, a lower
saddle height is often better for some
riding maneuvers. This allows a better control of
the CENTURION pedelec.
Never apply grease or oil into a seat
G
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.
Make sure not to overtighten the binder
G
bolt of the seat post clamp (e). Other-
wise you may damage the seat post or
the frame. Risk of an accident!
Never ride your bike with the seat post
G
drawn out beyond the limit, maximum or
stop mark (f)! 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.
If the seat post does not move easily in-
A
side the seat tube or if it cannot be tight-
ened sufficiently, ask your CENTURION
dealer for advice. Do not use brute force!
Tighten carefully by approaching the
A
prescribed maximum torque value in
small steps (0.5 Nm increments) and
e
check in between the proper fit of the compo-
nent. Never exceed the maximum torque value
indicated by the manufacturer!
If your CENTURION pedelec has a Vario
I
seat post (g), you can find more infor-
mation in your comprehensive original
CENTURION user manual and in the instructions
of the component manufacturers on the enclosed
CENTURION CD-ROM.

Adjusting the height of the handlebars

The height of the handlebars compared to the sad-
dle and the distance between saddle and handle-
bars determine how much your upper body will be
inclined forward (h). 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
g
less comfortable, because it increases the strain on
your wrists, arms, back, upper body and neck.
For safety reasons, CENTURION only assembles
Aheadset -stems. This system requires special
®
knowledge. In this regard, the descriptions hereafter
may be incomplete.
