Removing the wheels
Please note that the instructions provided here are
only examples. Make sure you respect the relevant
manufacturer’s guidelines or talk to your approved
O2Feel reseller.
Removing the front wheel
•
If your bike is equipped with quick releases,
unscrew them according to the manufacturer’s
instructions.
•
If your bike is equipped with axle nuts, unscrew
them with a suitable spanner by turning anti-
clockwise.
•
If the front wheel is protected against being
unscrewed thanks to the particular shape of
the derailleur hangers, continue to unscrew the
nuts by turning them anti-clockwise. When the
washers and the nuts are no longer touching
the derailleur hangers, remove the front wheel
from the fork.
Removing the rear wheel
•
If your bike is equipped with a rear derailleur,
position it on the smallest cog. In this position,
the gear changing mechanism will not get in the
way of removing the wheel.
•
If your bike is equipped with quick releases,
unscrew them.
•
If your bike is equipped with axle nuts, unscrew
them with a suitable spanner by turning anti-
clockwise.
•
Pull the gear shift mechanism back slightly.
•
Raise the bike a bit.
•
Remove the wheel from the frame.
•
If you cannot remove the rear wheel yet,
continue to open the quick release by turning
the locknut anti-clockwise.
•
Give the top part of the wheel a slight tap with
the palm of your hand.
•
The wheel will come away.
2.5.4 Headset
The headset is what holds the fork in the frame.
When it is in the right position, the headset can
turn easily. It must not be loose however.
The headset goes through a lot thanks to impacts
on rough surfaces. It can become loose or get
messed up. Check the position of the headset
regularly (it mustn’t be too tight or too loose). The
headset can break if it is not adjusted properly or is
too tight. This is why it should always be adjusted
by your approved O2Feel reseller.
If the headset is too loose, this can damage the
cups or the fork.
