HANDLING OF QUICK-RELEASE FASTENERS AND
THRU AXLES
QUICK RELEASE FASTENERS AND THRU AXLES
Most Megamo bicycles are equipped with quick releases and thru axles that
allow you to quickly adjust, mount and dismount components. Each time you
use your Megamo bicycle you should check that all quick releases/ thru axles
are tightened securely before use. Handle quick releases/thru axles with the
utmost care, as your safety depends directly on them.
Use quick-release fasteners/through axles correctly to avoid accidents.
Do not touch the brake disc immediately after stopping - risk of burns! Always
allow the brake disc to cool down before opening the quick release.
Procedure for the secure attachment of a component with quick-release
fastener and thru axles:
Open the quick-release/through shaft. You should now be able to read “open”.
Make sure that the component to be fastened is positioned correctly.
Move the lever to the clamping position until “close” can be read on the outside
of the lever. From the start of the closing movement to the halfway point, the
lever should be very easy to operate (see gure C).
After that, the lever should offer more and more resistance until it eventually
becomes difcult to move. Push with the base of your thumb and pull with your
ngers on a xed part, e.g. fork or upper rear stay, but never pull on a brake disc
or spoke (see gure D).
The quick release essentially consists of two
control elements:
A - The lever on one side of the hub which
converts the closing movement into
clamping force.
B - The tightening nut on the opposite side
of the hub, which adjusts the preload on a
threaded rod (the quick-release shaft).
