Operating instructions

Open the little thin plastic tube with a needle, a point-
ed spoke or a very small Phillips head screwdriver
(a).
The outer housings are mounted to the brake lever/
shifter units and to the AX-Lightness and engage
brake callipers with cable stops.
As a preventive measure for creaking noises and cor-
rosion, apply a little grease to the cable stops and the
counterbearing on the brake calliper.
Grease the inner cables by pulling them through
some bearing grease between thumb and index n-
ger
(b), while inserting the cables through the hous-
ings and the cable stops to the brakes.
Slide the outer housings completely into the mounts
on the brake lever/shifter units and into the cable
stops at the brake. Fix the housings in two to three
areas with two to three tightly wound layers of insula-
tion or fabric tape to the handlebars, before winding
on the bar tape
(c).
Insert the inner cable through the adjustment bolt
and slide the outer housing completely into the ad-
justment bolt.
Release the bolt of the yoke-type brake cable clamp
and remove the slotted cable clamping part. Move
the yoke over the brake cable and slide the clamping
part on the cable
(d). Slide the clamping part com-
pletely into the yoke with the slot being positioned
crosswise to the yoke (e). Press the AX-Lightness and
engage brake a little together. Hang the yoke back
into the brake arm mount and tighten the cable.
Tighten the Allen screw with a 3 mm key until the
Bowden cable is a little tight.
Hold the brake cable xing tight with an 8 mm
open-ended wrench and tighten the Allen screw
with a torque wrench to 3 Nm
(f).
Adjust the AX-Lightness and engage brake, as de-
scribed in the chapter “Synchronising and read-
justing the brakes”. Check once again the cable t
at all stops.
Forcefully pull the brake lever to the handlebars
(g)
several times. This stretches the cables and crushes
the outer housings a little. Readjust as the lever travel
increases.
Shorten the inner cable by using the cable cutter by
about one to two centimetres after xing the brake
cables.
Protect the sharp-edged inner cable against fraying
with a cable end sleeve (h).
G
Bowden cables and brake cables dier a lot
and must therefore not be mixed up. The
inner cables of Bowden cables are slimmer
and have a clearly smaller head. The outer
housings of Bowden cables have wire-rein-
forcements in pull direction, which prevent
the housings from being crushed. The outer
housings of brake cables, in contrast, have
a spiral-shaped steel reinforcement which
makes them a little more exible than their
Bowden cable counterparts.
I
With some brake lever/shifter units you can
decide on your own, whether both cables
run in the handlebars’ front or whether the
one runs in the handlebars’ front and the
other one in the rear. Your decision primari-
ly depends on the handlebars used.
I
Make sure the stem is in the highest posi-
tion, otherwise you will no longer have the
possibility to change the handlebar posi-
tion without mounting new cables.
