Place the disc brake A (fig. 1) on the

paying attention to the rotation sense
given by the arrow C engraved on the
rotor’s flange, and lock it in place with

1.2 Installing the kit
Proceed followingly:
- Place the pump body on the bar in
the desired position and lock it in
place with the screw (1) using a tigh-
tening torque of 2,5 Nm ± 5%.
The two screws have to be tigh-
tened alternately and at the
same distance.
If the hose length needs to be adjusted
see paragraph 2.3, if not proceed with
the positioning of the hose on the bicy-
cle, bearing the following in mind:
– the hose needs to be attached to the
fork or frame in a way that does not
interfere with the free flow of fluid
through the hose;
the hose should not make curves
smaller than a 40 mm diameter and
should not interfere with any moving
part of the bicycle;
for easy assembly of the hoses on
the bicycle, formula has developed a
custom made hose holder zip tie
that can be ordered as an
accessory.
