bike, including in difficult braking conditions.
Incorrect us of additional suspension elements in
the braking system (power regulators) may cause
serious falls. The required suspension power of
the power regulator depends on the total weight
of the bike.
When the brake pads are so worn that you can no
longer see the grooves, get them replaced by your
approved O2Feel reseller.
Adjusting the brakes
The brakes on your bike will have been adjusted
correctly when they left the factory or by your
reseller. The space between the brake pad and
the rim must be between around 1 and 1.5mm.
However, brake pads are subject to wear. The
space increases with use and the travel of the
brake lever gets longer and longer. For this reason,
you must check your brakes regularly and adjust
them when the travel of the brake lever is too
longer and the brake no longer works properly.
Follow these steps to check your brakes:
•
Press the brake lever for the front wheel hard,
then for the rear wheel, as you would do when
cycling in difficult braking conditions. Then push
your bike forwards.
•
The back wheel should not move.
•
The front wheel should slow down until the bike
starts to tilt forward.
2.5.3 Wheels
Checking the wheels
The wheels are the point of contact between the
bike and the ground. Ground surface irregularities
and the weight of the cyclist put a significant strain
on wheels.
The wheels are carefully checked and aligned
before delivery. However, the spokes will align
themselves over the first few miles that you cycle.
Get your wheels checked by your approved
O2Feel reseller after travelling 100 kilometres and,
if necessary, get them realigned. After that, make
sure they are checked regularly when carrying out
maintenance on your bike.
The wheel can be attached to the frame and the
fork in different ways. As well as the common
systems with which the wheel is attached thanks
to axle nuts or quick releases, there are different
kinds of wheel axles. They can be screwed on or
attached using different kinds of quick releases.
Checking the hub
Follow these steps to check the hub:
Lift the wheel and spin it around.
When you do this, make sure the wheel continues
to turn for a few spins, then stops. If it stops
suddenly, a bearing is damaged.
To check to see if the hub is loose, try to move the
wheel sideways (both ways) in the fork or in the
rear structure.
If there is some movement between the bearings,
or if the wheel does not turn easily, ask a specialist
reseller to adjust the hub.
Checking the rims
Rims will experience more wear if you are using a
rim brake.
A worn rim loses stability and is therefore more
likely to get damaged. A misshapen, cracked or
broken rim can cause serious accidents. Stop
riding the bike if you notice any changes to the
rim. Ask your approved O2Feel reseller to check
the damaged rim.
The rims on bikes bigger than 24” are equipped
with a wear indicator. A characteristic line can be
found on the side of the rim, or there will be a
groove all around the rim.
Replace the rim as soon as you notice any marks
(grooves, coloured areas) anywhere on the rim, or
if an engraved marking disappears or any coloured
writing becomes worn.
If the wear indicator is a groove or several points
on the side of the rim, replace the rim as soon as
these marks disappear.
Tyres
There are lots of different kinds of tyres. Their
properties and their rolling resistance depends on
their profile.
Do not exceed the stipulated inflation pressure for
the tyre. If you do, the tyre could burst.
Pump air into the tyre to achieve at least the
recommended minimum inflation pressure. If the
pressure is too low, the tyre could come away
from the rim.
