Handling the quick releases or quick release axles
Quick releases or quick release axles [ Bike RX ] on the
front and rear wheel and on the seat post allow you to
mount and dismount wheels easily and adjust the seat
height to the height of the cyclist. You should check
that the quick releases or quick release axles are firmly
tightened before each trip and the wheels and seat
post are firmly mounted on the bike.
When closed, the quick release exerts the clamping
force needed to fix the components in place using
an eccentric. The locking nut on the opposite side of
the hub sets the clamp’s pre-stress.
The wheel quick releases or quick release axle levers
are located on the front and rear wheel on the side
opposite the derailleur, i.e. on the left-hand side when
you face the direction of travel. When mounting the
wheels, make sure that the quick releases are
always on this side to prevent improper mounting.
When parking your bike, make sure that the parts
clamped with quick releases are adequately secured
against theft.
Securely mounting the wheels and seat post
Your bike has either one-step or two-step quick
releases or a quick release axle. To open the two-step
quick releases, first lift the larger lever. Then open the
second lever. The word ‘Open’ should now be visible
on the quick release.
Loose components.
If quick releases or quick
release axles are not secured properly, components
may become loose and cause you to crash. Check to
make sure all quick releases or quick release axles
are secure and tighten them if necessary.
WARNING
CAUTION
One-step quick releases have a single lever. You only
have to open this lever.
You open the quick release axle [ Bike RX] by turning
the lever in an anti-clockwise direction. To make it
easier to handle, you can raise the lever slightly and
move the lever several times.
To close the quick release, move either both and/or
one lever to the locking position at the same time.
The lever can be readily moved over half of the
clamping range. Then, the leverage force must
increase substantially and can only be moved with
difficulty over the remainder of the clamping range.
This way, you can be sure adequate clamping force
has been applied.
You close the quick release axle by turning the lever in
a clockwise direction. To do so, move the lever several
times. Then raise the lever and turn it to the required
position.
Once closed, the quick release is parallel to the wheel.
Make sure that there is no risk of external contact
accidentally opening the lever.
Make sure the quick release is securely positioned
when closed. Attempt to twist it. If it can be twisted,
you will have to increase the pre-stress with the nut
located on the other side.
Hot brake disc.
The brake disc may heat up when
the brake is applied. There is a burn risk. Avoid coming
into contact with the brake disc. Let the brake disc
cool off before using the wheel quick releases.
