bike, including in diffi cult 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 diffi cult 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.
Hydraulic disc brakes
Hydraulic disc brakes are fi tted with a master
cylinder next to the manual brake lever. The
hydraulic fl uid travels to the brake cylinders via a
brake line. The brake pads are pressed against the
disc by pistons. This type of brake is very powerful
and does not require much maintenance.
Whenever you adjust them, test the brakes by
pushing the bike fi rmly whilst applying the brake
lever. Only use your bike if it brakes safely.
Regularly check to make sure that the tubes and
outer casings are properly sealed, including every
time you go out. Tubes and fi ttings that are not
sealed properly may result in braking fl uid leaks
and prevent the brakes from working properly.
If any fl uid leaks from the braking system, stop
using the bike and get a specialist to carry out the
necessary repairs immediately.
If you cycle with the brakes in this state, there is a
signifi cant risk of the brakes failing.
When transporting or storing the bike upside
down, air bubbles can form in the braking system
reservoir. This can aff ect the performance of your
brakes.
Cleaning the braking system
If the brake pads come into contact with oil or
grease, they will need to be replaced. If the brake
disc comes into contact with oil or grease, it will
need to be replaced. Failure to do so will hinder
the performance of your brakes signifi cantly..
Use isopropyl alcohol, soapy water or a dry cloth
to clean and maintain the braking system. Do
not use commercially available noise-reduction
solutions or cleaning products for brakes as they
may damage certain parts, such as the seals for
example.

2.5.2 Derailleurs

Your O2Feel bike will be delivered as carefully as
we can. Contact your approved O2Feel reseller
immediately if any faults occur.
However, here are some basic rules for your
rear derailleur:
The cable stops are the fi rst thing to adjust on
your rear derailleur. Quick reminder: the cable
stops defi ne the position of the derailleur from the
small cog to the big one and prevent the chain
from jumping. They are in the right position when
the derailleur moves from top to bottom without
derailing and when you don't hear any clicking on
the smallest and biggest cogs.
– Adjusting the cable stop on the small cog side
(High cable stop): aligning the chain and the guide
roller with the small cog
