How to Fasten Components Securely with a Quick-Release
Open the quick-release. The marking
“open“
on the lever should be-
come visible now
(a)
.
Make sure the component to be fastened is in the correct position.
You can find further information in the chapters
“wheels and tyre
equipment”
and
“adjusting the wheeler bicycle to the rider”
and in the instructions from the parts manufacturers, which you can
find on the enclosed CD.
Move the lever back, as if to close it. Now you should be able to read
”Close“ on the outside of the lever
(b)
. When you start closing the lever
you should feel virtually no resistance with your hand until half way.
Over the second half of its travel the resistance you feel should increase
significantly
(c)
. Towards the end of its travel you should need very
much strength to close the lever. Use the ball of your thumb to push it
in all the way while your fingers pull on an immovable part, such as the
fork or the rear stay, but not on a brake rotor or spoke.
In its end position, the lever should be at right angles to the quick-
release axle
(d)
, i.e. it should not stick out to the side. The lever should
lie close to the frame or the fork so that it cannot be opened acciden-
tally. Make sure, however, that the lever is easy to handle for actual
quick use.
To check whether the lever is securely locked, apply pressure to the end
of the lever and try to turn it while it is closed. If you can turn the lever
around, open it and increase the preload. Screw the tightening nut on
the opposite side clockwise by half a turn. Close the quick-release lever
and check it again for tightness.
Finally lift the bicycle a few centimetres so that the wheel no longer
touches the ground and hit the tyre from above
(e)
. If it is properly
fastened, the wheel will remain firmly fixed in the drop-outs of the frame
or fork without producing any rattling.
If your seat post is equipped with a quick-release mechanism, check
whether the saddle is firmly fixed by trying to twist it relative to the
frame
(f)
.
With the
dt Swiss rwS
system
(g)
the clamping force is not created
via a cam, but by tightening a bolted connection with a lever.
Tighten the system by turning the lever clockwise and by keeping the
clamping nut tight.
Depending on frame or fork the lever may touch either frame or fork
during tightening. If it does, remove the lever, release it, let it engage
again before you retighten it.
In its end position the lever should lie close to the frame or the fork so
that it cannot be opened accidentally.
g
Do not touch the rotor directly after having stopped – you
may burn your fingers! Always let the rotor cool down be-
fore opening the quick-release!
g
With an insufficiently closed quick-release the wheel can
come loose , thus creating a serious risk of accident!
a
If your bicycle is equipped with quick-releases, be sure to
lock it to an immovable object together with the wheels
when you leave it outside.
i
To be on the safe side you can replace the quick-releases
by special locks
(h)
. They can only be opened and closed
with a special, coded key or an Allen key. If you are in doubt
or if you have any questions, contact your bicycle dealer.
