stops, and make sure you don't undo any
settings.
•
Make sure you don't drop the push rod in case
it gets dirty or twisted as it is coated with a
special grey grease.
•
At this point, the chain is still in position.
•
Once the bell has been removed, the rest of the
process is similar to that for any bike.
•
You will see the wheel nuts, which you will need
to loosen (14mm or 15mm spanner) but not
unscrew completely.
•
The wheel will then be released from the frame,
but not from the chain.
•
Loosen it by moving the wheel forward, or by
playing with the chain tensioner (depending on
the confi guration).
Reassembly:
Follow the steps in reverse order.
There is nothing particularly diffi cult here, but you
do need to make sure the bell is fi xed properly in
the stop before immobilising it by tightening it.
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.
