Operating instructions

After replacing a sprocket assembly or mounting the
rear wheel for the rst time onto your bike you need
to check the functioning of the gears.
Please make sure the limit stops are properly adjust-
ed. An inappropriate adjustment can lead to a failure
of the drive or make the rear derailleur collide with
the spokes – this can damage your bicycle or even
result in an accident!
A
The lock nut of the sprocket assembly must
engage four full turns at least, otherwise
there is the risk that the drive is damaged.
G
Check the functioning of the gears after the
reassembly of the sprocket assembly
(a).
Dismounting the sprocket assembly
Start with mounting a plug tool (b) that matches ex-
actly the prole of the sprocket assembly lock nut.
Secure the tool, if necessary, with the quick-release.
However, instead of closing the quick-release as usu-
al, be sure to only tighten it a little to ensure that the
plug tool is secure on the lock nut.
This is to prevent the tool from tilting or slipping o
abruptly. Hold the sprocket assembly tight with a
chain whip. Open the lock nut by using a ring or fork
spanner matching the extractor tool (c).
Open the quick-release bit by bit as the lock ring
comes loose so that you can screw it o.
Remove the sprocket assembly from the freewheel
body. The rst sprockets and intermediate rings are
mounted individually (d). If they cannot be removed,
they may have worked themselves a little into the
surface of the sprocket assembly. Free the sprockets
by inserting two wide-blade screwdrivers opposite
each other into the gaps at the outermost sprocket.
Mounting the brake rotors
AX-Lightness and engage MTB disc wheels are made
for 6-hole mountings in accordance with the IS 2000
standard (e).
Place the rotor on the hub ange (f). Observe the ar-
row on the rotor (g). It must be visible from outside
and point in the wheel’s running direction.
Check whether the rotor engages fully with the hub
ange. If it does not, both the rotor and the hub
ange need to be measured. Ask in this case your AX-
Lightness and engage dealer. Be sure to always use
original parts supplied by the brake manufacturer
(rotors and bolts).
Insert all six bolts typically treated with liquid bolt
retaining compound but without grease and tighten
them with a Torx or Allen key until their heads evenly
engage with the rotor.
If necessary, apply liquid bolt retaining compound
(Loctite) to the bolt threads, if they have not yet been
treated with retaining compound by the manufactur-
er.
Turn the rotor in the opposite direction to the arrow
until it engages with the bolts. Tighten the bolts al-
ternately by using a torque wrench to a torque of 3
to 4 Nm (h) to begin with. Then tighten the bolts to
the torque value recommended by AX-Lightness or
engage .
