Always check the screws very diligently for
signs of corrosion. Rust at the screw heads
may also lead to the screw seizing in the
thread. When the metallic and shiny coating
of galvanised screws comes off and discloses
dull, gray-brown steel you have to exchange
the screw.
When you exchange screws please only use
screws of the same type. Screws come in
different strength classes. Please only use
galvanised screws of the same type and
strength, corresponding to the German
strength class 8.8 or stainless steel screws
grade A2-70, when not given any other
recommendation. If you are in doubt, please
ask your specialist dealer.
Quick release levers
Quick release levers hold wheels and seat in
position. A quick release lever consists of two
basic parts: the lever on one side provides the
clamping force. With the adjusting nut on the
other side you adjust the clamping tension on
the screw thread.
Danger!
An incompletely or improp-
erly closed quick release can result in parts
coming loose and hence in a crash, possibly
resulting in serious injury.
To open the quick release, move the lever
away from the frame. In doing so, the inscrip-
tion "open" should be visible on the lever.
To close the quick release, move the lever
with power in the other direction so that the
word "close" is visible on the outward side of
the lever. At the start of the lever's motion,
for, say, half of its movement, the lever should
move very easily, without any clamping action.
In the second half of the lever's movement the
force on the lever should increase considera-
bly, corresponding in the end to 15 – 20 kg
(46 lbs). In its final position, the lever should
come parallel with the bicycle and should not
stick out to one side.
Check the security of the lever by attempting
to twist the lever. If the lever can be made to
pivot around in a circle the clamping is too
loose. You must re-open the quick release,
hold the lever and increase the clamping
tension. Do this by screwing the adjustment
nut on the other side by half a turn. Close the
lever and check the clamping anew.
Finally, check that the part being secured is
firmly fixed: Lift each wheel several inches off
the ground and give it a slap onto the tire
from above. A properly fixed wheel will re-
main secure in the frame's dropouts.
Parts that are fastened with a quick release
open easily. Thus, they are more susceptible
to theft. Therefor, always secure the wheels
with a lock when you park your bicycle. It is
also possible to exchange the quick releases
with special security screws (e.g. from P
IT-
LOCK
) that can only be opened with a special
tool. For this please consult your local special-
ist dealer.
