How to use quick-releases and
thru axles

Quick-releases

Most CENTURION pedelecs are fitted with quick-re-
leases (a) to ensure fast adjustments, assembly
and disassembly. Be sure to check whether all
quick-releases are tight before you set off on your
CENTURION pedelec. Quick-releases should be
handled with greatest care, as they affect your safety
directly.
Practice the proper use of quick-releases to avoid
any accidents.
Quick-release mechanisms essentially consist of two
operative elements:
1. The hand lever (b) on one side of the hub which
creates a clamping force via a cam when you
close it.
2. The tightening nut (c) on the other side of the
hub with which the preload on the threaded rod
(quick-release axle) is set.
Do not touch the brake disc directly
G
after having stopped, e.g. after a long
down-hill ride, you may burn your fin-
gers! Always let the brake disc cool down before
opening the quick-release.
Make sure the levers of both wheel
G
quick-releases are always on the side
a
opposite to the chain. This will help you
to avoid mounting the front wheel accidentally
the wrong way round. In the case of CENTURION
pedelecs with disc brakes and quick-releases
having a 5-mm axle, it may be reasonable to
mount both quick-releases with the lever on the
side of the chain drive. This helps you not to come
into contact with the hot brake disc and prevents
you from having your fingers burnt. If you are in
b
doubt or if you have any questions, contact your
CENTURION dealer.
Never ride your CENTURION pedelec
G
without having checked first, whether
the wheels are securely fastened (d).
With an insufficiently closed quick-release the
wheel can come loose, thus creating a serious
risk of accident!
c
If your CENTURION pedelec is equipped
A
with quick-releases, be sure to lock the
frame to an immovable object together
with the wheels when you leave it outside.
