Operating instructions

Before every ride
Check the following points before setting o on your
AX-Lightness and engage bicycle:
1. Verify the tight t of the stem on the fork steerer
and of the handlebars in the stem. For more infor-
mation see chapters “Mounting AX-Lightness
and engage Aheadset®-stems” and “Mounting
AX-Lightness and engage handlebars”.
2. Are the quick-release levers or nuts of the front and
rear wheel and of the seat post properly closed (a)?
Improperly closed quick-releases or thru axles can
cause the wheels of AX-Lightness and engage bicy-
cles to come loose. and result in serious accidents!
For more information see chapters “Quick-releas-
es”, “Thru axles” and “Wheel mounting (moun-
tain bike/road racing bike)”.
3. Are the tyres in good condition and do they have
sucient pressure (b)? Do at least a thumb test by
pushing your thumb down on the tyre. The tyre
should only yield a little. For more information see
chapter “Tyres, inner tubes, rim tape, ination
pressure”.
4. Check whether the AX-Lightness and engage
headset is free of play and moves easily (c). Perform
a functional check as described in chapter “Check-
ing the headset”.
5. Spin the wheels to check whether the rims are true.
Watch the clearance between brake pad and rim
(d), or, in the case of disc brakes, between rim and
frame or fork. Untrue rims can be an indication of
tyres with ruptured sides, broken axles and a dam-
aged rim. As you look over the bicycle and nd
out that in the brake/wheel area the clearance on
the right side diers from that on the left side, the
AX-Lightness and engage wheel or the brake has
come out of its centred position.
6. Test the brakes in stationary by rmly pulling the
brake levers towards the handlebars
(e). The brake
pads of the rim brakes must hit the rim sides with
their entire surface. They must not touch the tyres.
You should not be able to pull the lever all the way
to the handlebars!
With disc brakes you should have a stable pressure
point at the lever. Oil or brake uid must not leak
out onto the rotor or stopping power will be re-
duced and cause unsafe braking performance. For
more information, see your general bicycle user
manual.
7. Let your AX-Lightness and engage bicycle bounce
on the ground from a small height
(f). If there is any
rattling, see where it comes from. Check the bear-
ings and the bolts, if necessary.
8. Do not forget to take a high quality D- (g) or chain
lock with you on your ride. The only way to eec-
tively protect your AX-Lightness and engage bicy-
cle against theft is to lock it to an immovable ob-
ject.
9. If you want to ride on public roads, make sure your
AX-Lightness and engage bicycle is equipped ac-
cording to the regulations of your country (h). Rid-
ing without lights and reectors in dark or dim con-
ditions is very dangerous, because you will be seen
too late or not at all by other road users. A lighting
set that corresponds to the regulations is a must on
public roads. Turn on the lights as soon as dusk sets
in.

Please note that the braking eect and
road grip of your bicycle are both greatly
reduced in wet conditions. Be particularly
cautious and do not ride as fast as under
dry conditions.
