Checking and readjusting
The derailleur gears of your bike were carefully
adjusted by your CENTURION dealer before delivery.
However, Bowden cables may stretch a little over the
first kilometers, making gear shifting imprecise and
the chain rattle.
Adjusting the front and rear derailleur
(d)
accurately
is a job only for an experienced mechanic. If you want
to try to do the adjustment on your own, observe in
addition the operating instructions of the gear manu-
facturer on this CENTURION CD-ROM. Contact your
CENTURION dealer if you have any problems with
the gears.
I
For your own safety, bring your
CENTURION bike to your CENTURION
bike dealer for its first inspection after
100 to 300 kilometers, 5 to 15 hours of initial use
or four to six weeks, and at the very latest after
three months.
Adjusting the rear derailleur
Increase the tension of the Bowden cable by turning
the adjustable cable stop at the shifter lever or the
adjusting bolt through which it runs into the rear
derailleur
(e)
. To do so, shift to the smallest sprocket
and turn the bolts counterclockwise in half turns until
the cable is slightly tensioned. After tensioning the
Bowden cable check whether the chain immediately
climbs onto the next larger sprocket. To find out you
either have to turn the cranks by hand
(f)
or ride the
CENTURION bike and shift through the gears.
If the chain easily climbs onto the next larger
sprocket, check whether it just as easily shifts to the
small sprockets. If it does not, release the respective
adjusting bolt a little. You may need several tries.

Adjusting the front and rear derailleur
accurately is a job for an experienced
mechanic. Observe in any case the op-
erating instructions of the gear manufacturer on
this CENTURION CD-ROM. If you have any prob-
lems with the gears, contact your CENTURION
dealer.
I
Ask a helper to lift the rear wheel. By
turning the cranks and shifting through
you can easily check the function.
Adjusting the limit stops
The rear derailleur is equipped with limit screws
(g)
which limit the movement range of the derailleur, thus
preventing the derailleur and chain from colliding with
the spokes or the chain from dropping off the small-
est sprocket. The limit screws are adjusted by your
CENTURION dealer. They do not alter their position
during normal use.
If necessary, correct the position by means of the limit
screws. The limit screws on rear derailleurs are often
marked “H” for high gear and “L” for low gear. “High
gear” means that the chain is running on the smallest
sprocket. Turn the screw clockwise to shift the rear
derailleur towards the wheel and counterclockwise to
shift it away from the wheel.
