HANDLEBAR ALIGNMENT WITH THE FRONT WHEEL
Check the absence of play in the union between the power and the handlebar, and the
steering axle and the power, trying to move it with respect to the front wheel blocking
the wheel with both legs.
Check that all screws are tightened with the tightening torques indicated in the table in
this manual.
FRONT SUSPENSION ADJUSTMENT
The front suspension, manufactured by JOTAGAS, is equipped with an inverted fork oil
pneumatic, adjustable in load and preload, and with hydraulic expansion regulation.
Preload
The adjustment of the fork preload is carried out by the rotary knob located on the
upper part of the left side tube. Blue color control.
Turning the knob clockwise increases the preload of the suspension.
The preload of the front suspension allows to adjust the static travel of the front
suspension under the weight of the user and to avoid the loss of efficiency of the
suspension due to excess preload. The recommended value is between 12 and 30
mm.
Note that the preload must be readjusted according to the ground type and that in
courses with uniform terrain a higher preload reduces the user’s pedaling effort.
The fork is also equipped with a gas chamber in the damping system. The maximum
load pressure must never exceed 13 bar. The value of this pressure affects the
hardness of the suspension and will slightly modify the preload. We recommend a
value between 4 and 8 bar.
To determine the correct preload, it must be taken into account that in
no case should the front suspension stop at its end of travel.
Hydraulic
The regulation of the hydraulics is located in the upper part of the right tube of the
fork. Red color control.
Turning the knob clockwise decreases the speed of return of the suspension, closing
the hydraulic passage.
