WARNING: A quick-release or
other wheel attachment device that
is not correctly adjusted and closed
can cause the wheel to be loose or
come off, suddenly stop the wheel,
decrease your control, and cause
you to fall. Make sure the wheels
are correctly attached before you
ride your bicycle.
Types of wheel aachment devices
See these devices in Figure 3.28:
• Tradional quick-release
• Threaded axle and nut
• Threaded skewer and nut
(hex wrench type)
• OCC (Over-Center Cam) thru-axle
• DT RWS thru-axle
• Make sure a locked quick-release lever can
not be turned (Figure 3.30).
• When a quick-release is correctly locked, the
clamp-force is sucient to cause metal-
into-metal engagement (embossing) of the
dropout surfaces.
For more informaon about the correct
opening and closing forces on an OCC lever,
read the Actual Measurements.
Test the wheel aachment
For the device(s) on your bike, follow the
instrucons to make sure your wheels are
correctly aached. If the aachment does not
pass a test, aach the wheel again or take
your bicycle to your retailer for service. Do
the tests again before each ride.
• Li your bicycle and hit the top of the re
with a solid blow (Figure 3.29). The wheel
should not come o, be loose, or move
from side to side.
• For a nued axle or threaded skewer, make
sure the device it ghtened to the correct
torque specicaon.
• For a quick-release lever, make sure the
resistance is correct as you move the lever
to the CLOSE posion.

Actual Measurements for an OCC (Over-

If more than 45 pounds (200 Newton) force
is necessary to lock the lever, slightly loosen

(53.4 Newton) force is necessary to release
the lever, slightly ghten the adjustment-nut.
