With the ROLLER 2, you can remove the “limits” of
your imagination. The new model of our miniwing will
break all your previous conceptions. It is synonymous
with speed, precision and manoeuvrability, all in an
accessible and surprisingly versatile wing.
The ROLLER 2 will allow you to take speed-flying to
another dimension, as it is the biggest advance in this
category, while maintaining safety above all else.
We are sure you will enjoy flying this paraglider and
you will soon discover the meaning of our philosophy:
“Give importance to the small details to make
big things happen”.
This is the user manual and we recommend you read
it carefully.

It is important to note that prior training is essential when beginning speed-flying. In terms of safety, it is
paramount that the pilot’s skill level matches the “performance” of the glider and/or the objectives of the
pilot. The control, safety and freedom provided by the ROLLER 2 depend directly on the pilot’s level of skill

2.2 PROCEDURE
Take the paraglider out of the rucksack, open and unfold it on the ground with the lines positioned on the
undersurface, oriented in the direction of inflation. Check the condition of the fabric and the lines for defects.
Check the maillons/IKS connecting the lines to the risers to make sure they are fully closed and tightened.
Identify, and if necessary, untangle, the A and B-lines, the brake lines and corresponding risers. Make
sure that there are no knots Identify, and if necessary, untangle, the A, B and C-lines, the brake lines and
corresponding risers. Make sure that there are no knots.
2.3 CONNECTING THE HARNESS
The ROLLER 2 risers are colour-coded.
Right: green
Left: red
This colour-coding makes it easier to connect the wing to the correct side and helps prevent pre-flight errors.
Correctly connect the risers to the attachment points so that the risers and lines are correctly ordered and
free of twists. Check that the IKS or carabiners are properly fastened and securely locked.

2.5.1 SPEED SYSTEM ASSEMBLY
By speed system we mean the speed-bar that the pilot pushes to accelerate, together with the two lines that
connect it to the cords on the the risers. Once you have decided on the type of speed-bar you wish to use,
it is necessary to proceed with its installation. Something to consider:
The pilot can use the type of speed-bar they consider appropriate depending on the type of
harness used and their preferences.

into each other to interlock, ensuring their use and connection/disconnection. However, any safe
splicing system can be used.

the feet on the speed-bar (not supplied as standard on this model) which the pilot must install by connecting
it to the speed system on the risers (See 2.5.1: “Speed system assembly”).
The speed system uses an action/reaction system. Released, the speed-bar is set to neutral. When the bar is
pushed using the feet, the wing accelerates. The speed can be regulated by varying the pressure on the bar.
Once the pressure on the bar is released, the speed system returns to the neutral setting.

The ROLLER 2 is able to stay airborne in strong winds when conventional paragliders can no longer fly.
However, if conditions are very turbulent, we recommend not flying until the forecast improves.
All paragliders must be piloted for the prevailing conditions and the pilot is the ultimate safety factor.
We recommend active flying in turbulent conditions, always taking measures to maintain control of the wing,

wing flying straight, while applying light brake pressure to that side if necessary. Normally, the collapsed side
of the wing should then recover and reopen by itself. If it does not, try to weight-shift towards the collapsed

the turn). Once the collapsed side is open make sure you return to normal flying speed.
