Always make sure changing gears
makes as little noise as possible and is
absolutely jerk free.
A
Make yourself familiar with the opera-
tion of your gears in a place free of traf-
fic and practice operating the shifters
or the twist grips as well as the brake system,
before using your bike on public roads.
I
There are some multi-speed hubs where
the effects of the back-pedal brake de-
pend from the selected gear. Read the
gear manufacturer’s operating instructions on
this CENTURION CD-ROM carefully and make
yourself familiar with the brake function before
using your bike on public roads.
I
Removing and mounting the wheels is
not the same as with derailleur gears.
With this fact in mind read the chapter
“Tire puncture” and observe the notes given in
the operating instructions of the manufacturer on
this CENTURION CD-ROM.
Checking, readjusting and servicing
Multi-speed hubs require only little maintenance and
need not be adjusted very often. Check the chain
tension, in particular when removing and mounting
wheels, and read the chapter “Chain - care and
wear”.
If the indexed gear change does not work trou-
ble-free, then contact your CENTURION dealer.
Adjusting multi-speed hubs
Shift into the fourth (4th) gear. Look from above at the
right-hand side of the hub
(a+b)
. There you can see
two yellow markings. These two markings must be at
the same height, i.e. they must produce a line.
Turn the adjusting screw at the shifter
(c)
until you
get just one single line.
G
Regularly check the reliable fit of the
bolted connection of the hub and, if nec-
essary, of the torque arm at the frame.
A
Shimano recommends for example
regular maintenance (oil change) every
5,000 km or every two years. Read the
operating instructions of the gear manufacturer
on this CENTURION CD-ROM or contact your
CENTURION dealer.
I
Observe the operating instructions of the
gear manufacturer on this CENTURION
CD-ROM. If you are in doubt or if you
have any questions, contact your CENTURION
dealer.
