Operating instructions

General notes on mounting
and compatibility
The wheel consists of the hub, the spokes and the rim
(a). The tyre is mounted onto the rim, either a tubular
tyre that must be glued on the rim or a clincher or
folding tyre which has an inner tube inside. There is a
rim tape running around the rim well to protect the
sensitive tube against the spoke nipples and the edg-
es of the rim well, which are often sharp.
A quick-release (b) or a thru axle connects the AX-
Lightness and engage wheels with the frame and the
fork.
The AX-Lightness and engage wheels are subjected
to considerable stress through the weight of the rider
and any carried baggage as well as through bumpy
road surfaces and terrain. The permissible total weight
for all AX-Lightness and engage wheels is 110 kg. Al-
though AX-Lightness and engage wheels are man-
ufactured with great care and delivered accurately
trued, spokes and nipples can lose a little tension on
the first kilometres/miles. Ask your AX-Lightness and
engage dealer to check and true up the wheels after
you have bedded them in over about 100 to 300 kilo-
metres (60 to 180 miles) or 5 to 15 hours of use.
After the bedding-in period, check the AX-Lightness
and engage wheels regularly. It will, however, rarely
be necessary to tighten the spokes.
a
Observe the permissible total weight of 110
kg so as not to overload the wheels.
g
Before replacing the tyres, make sure the
new tyres have the same size as the ones
mounted before. Bigger sized tyres may
collide with parts of the frame or the fork
and lead to a wheel blocking.
G
Please note that aero wheels may be aect-
ed by side winds and drift.
g
Be sure to check the dimensional
accuracy of tyres and rims. If in
doubt, bring your components
to your AX-Lightness and engage
dealer. He can decide, whether
this is a problem which can be
solved or whether the component
must be replaced.
A
Truing (retruing) wheels is a dif-
cult job which you should de-
nitely leave to a specialist.
A
To avoid any damage it is recom-
mended that you store AX-Light-
ness and engage wheels in a
wheel bag when transporting
your bicycle with the wheels re-
moved or when you do not use
them for a longer period of time.
Quick-releases and thru axles
Quick-releases
Most road racing and mountain bikes are tted with
quick-releases (c) to ensure fast adjustments, assem-
bly and disassembly. Be sure to check whether all
quick-releases are tight before you set o on your
bicycle. Quick-releases should be handled with great-
est care, as they directly aect your safety. Practise the
proper use of quick-releases to avoid any accidents.
Quick-release retention mechanisms basically consist
of two operative parts (d):
1. The hand lever on one side of the hub which cre-
ates a clamping force via a cam when you close it.
2. The tightening nut on the other side of the hub
with which the preload on the threaded rod
(quick-release axle) is set.
G
Make sure the levers of both wheel quick-re-
leases are always on the side opposite to the
chain. This will help you to avoid mounting
the front wheel accidentally the wrong way
round. If you are in doubt or if you have any
questions, contact your AX-Lightness and
engage dealer or our service centre.
G
Never ride a bike without rst having
checked whether the wheels are securely
fastened. Risk of accident!
A
If your AX-Lightness and engage 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 re-
place the quick-releases by special
locks. They can only be opened
and closed with a special, coded
key or an Allen key (e). If you are
in doubt or if you have any ques-
tions, contact your AX-Lightness
and engage dealer.
