With rim brakes the sides of the rims also serve as
braking surfaces. An untrue wheel can impair your
braking effect. It is therefore advisable to check the
wheels for trueness from time to time. For this pur-
pose lift the wheel off the ground and spin it with your
hand. Watch the gap between the rim and the brake
pads. If the gap varies by one millimeter or more, you
should ask your CENTURION dealer to true up the
wheel
(e)
.
G
Do not ride with untrue wheels. In the
case of extreme side-to-side wobbles,
the brake pads of rim brakes can miss
the rim and get caught in the spokes! This nor-
mally instantly jams the wheel and throws you off
your bike.
A
Loose spokes must be tightened at
once. Otherwise the load on the other
spokes and the rim will increase.

Truing (retruing) wheels is a difficult job
which you should definitely leave to your
CENTURION dealer.
Tire puncture
Flat tires are the most common cause of puncture
during cycling. However, as long as you have the
necessary tools and a spare tube or a repair kit, this
need not mean the end of your cycle ride. If your
wheels are attached with quick-releases to the frame
and the fork, you only need two tire levers and a
pump
(f)
.
I
Before removing a wheel, read the
chapters “Mounting wheels” and “How
to use the quick-releases”. If you are in
doubt or if you have any questions, contact your
CENTURION dealer.
Dismounting wheels
If your bike has mechanical rim brakes (cantilever
and V-brakes) you first have to unhook the brake
cable from the brake arm
(g)
. To do this, grip the
rim with one hand and press the brake pads and/
or arms together. In this position the usually barrel
shaped nipple of the lateral brake cable or the brake
hose (of V-brakes) can easily be disengaged.
If your bike has hydraulic rim brakes from Magura,
unlock its quick-release
(h)
on one side of the brake
and remove the brake from the brake mount.
