Therefore, if you notice that the braking effect dete-
riorates, stop and let the brake system cool down.
Sometimes, it will be enough to operate the front
and rear brake in an alternating pattern. If that will
not suffice, stop for a couple of minutes before you
set off again.
G
Brake cables which are damaged, e.g.
frayed, must be replaced immediately,
as they can otherwise fail in a critical
moment, possibly causing a crash!
G
If during braking the travel of the brake
lever increases, unusual noises occur
and/or the braking effect is clearly more
or less effective than usual, do not ride your bike.
In such a case contact your CENTURION dealer
immediately.
G
Check regularly whether the torque sup-
port is firmly attached to the frame or
fork. Use a torque wrench and never ex-
ceed the maximum torque values!
Checking and readjusting back-pedal brakes
The chain tension of bikes with back-pedal brakes
has to be checked and adjusted, if necessary, after
approx. 1,000 km or 50 hours of use. For more
details read the chapter “Chain - care and wear”.
G
Keep in mind that the back-pedal brake
is ineffective if the chain has jumped off.
Risk of an accident!
The gears
Derailleur gears
The gears of your CENTURION bike
(a-c)
serve to
adjust the gear ratio to the terrain you are riding on
and the desired speed.
A low gear (where in the case of derailleur gears
the chain runs on the small chainwheel and a large
sprocket) allows you to climb steep hills with mod-
erate pedaling force. You must, however, pedal at
a faster pace. High gears (large chainwheel, small
sprocket) are for riding downhill. Every turn of the
pedals takes you many meters forward at corre-
spondingly high speed.
G
Continue pedaling at reduced cadence
during gear shifting, however, at clear-
ly reduced pedaling force. In particular
when shifting through the chainwheels continue
pedaling slowly and without force.
H
With CENTURION pedelecs reduce the
cadence and the pedaling force short-
ly before you start shifting. In doing so
there is a short interruption of the drive. If you
continue pedaling, the high chain forces could
result in a chain failure.
A
Practice shifting gears in a place free
of traffic until you are familiar with the
functioning of the levers or twist grips of
your CENTURION bike.
