Operating instructions

» Do not release the nipples to true up a lateral or
vertical runout. Always re-tension the spokes to re-
gain the tension they have lost during riding.
» The nipples of AX-Lightness and engage wheels
that were in use for a rather long period of time
may “cling” to the spokes. It is advisable to start with
slightly releasing the nipples, i.e. by a quarter turn,
before you tighten them, to prevent the spokes
from being turned o during re-truing.
a
We from AX-Lightness and engage recom-
mend that you have your wheels trued up
solely by an AX-Lightness and engage deal-
er. Inappropriately tightened spokes can
cause irreparable damage.
Mounting the sprocket assembly
AX-Lightness and engage wheels are only available
with a free-wheel for Shimano and SRAM and with a
second one for Campagnolo sprocket sets.
If you have a Shimano and SRAM 10-speed assembly,
make sure to insert the thin intermediate ring on the
inside of the free-wheel before mounting the assem-
bly
(a) since you will otherwise not be able to fasten
it securely. You don’t need the ring, however, if you
have a 11-speed assembly.
AX-Lightness and engage freewheel bodies are made
of aluminium. Be sure not to t these lightweight
aluminium freewheel bodies with single sprock-
ets or with sprocket sets that are screwed together
from single sprockets with intermediate rings. Single
sprockets will eat their way into the softer material of
the freewheel body which makes a later dismount-
ing dicult. The freewheel body could be damaged
or notched on this occasion! Freewheel bodies with
such kind of damage are neither covered by the war-
ranty, nor by the guarantee.
Be sure to only use Shimano, SRAM and Campagnolo
sprocket sets with sprocket carriers. These sprocket
sets have the larger sprockets mounted on alumini-
um or plastic carriers. They provide a bigger contact
area, the stress being thus spread more ecient.
Spray the sprockets and the whole sprocket set with
wax (b) before mounting it and let it dry well. That
prevents corrosion and makes for an easier dismount-
ing at a later date.
Slide the sprocket carriers
(c), intermediate rings (d)
and the small individual sprockets (e) onto the pro-
led freewheel body. The prole is asymmetric to
ensure that the ramps of adjacent sprockets are opti-
mally positioned in relation to one another. Make sure
that the tooth number engraved on each sprocket
faces inward. If there are no engraved tooth numbers,
mount the sprockets so that the ramps face outward.
Grease the thread and the contact area of the lock
nut and tighten it by hand
(f) by one to two turns (g)
before applying a plug tool
(h). Tighten the nut with
a torque wrench tted onto the plug tool. Be sure to
observe the recommended torque value of 30 – 40
Nm, unless otherwise specied in the enclosed de-
scription of the hub manufacturer. Do not exceed the
maximum torque value. Too high tightening torques
can damage the thread.
Check the rm seat of the sprocket set by trying to
move it crosswise to the direction of motion. Finish
by turning the freewheel with the mounted sprock-
ets. Check it for ease of movement and make sure the
sprockets run true. If not, you need to dismount the
sprocket assembly and nd out the cause.
Loose sprocket sets may be caused by unsuitable in-
termediate rings. Try another intermediate ring or ask
your AX-Lightness and engage dealer for advice.
