to the neutral setting. 

The speed system is efficient, sensitive and precise. The pilot can use the 
system whenever they want during the flight. In the neutral position the 
glider will fly at the standard speed and glide. Using full speed-bar, the 
wing will fly at maximum speed, but the glide will be adversely affected.  

•Released speed-bar: the A, B and C-risers are aligned.
•Full speed-bar: the difference between the A - C-risers becomes 160 
m/m for all sizes.

Please note!
The use of the speed system results in changes to the speed and 
reactions of the wing. For more information, please see the certification 
report.

2.5.1 SPEED SYSTEM ASSEMBLY.

The speed-bar consists of the bar that the pilot pushes with their feet, as 
well as the two cords that connect it to the speed system components 
on the risers. Once you have chosen the type of speed-bar you prefer, 
you must install it. Some considerations:

• You should use the type of speed-bar you consider appropriate, 
depending on the type of harness, personal preferences, etc. 
• The speed-bar is detachable to facilitate its connection and / or 
disconnection to the risers as well as subsequent adjustment.
• To connect it to the harness, please follow the instructions of the 
harness manufacturer. The majority of harnesses have a speed system 
pre-installed. 
• The standard connection of the speed-bar to the speed system is via 
Brummel hooks, where two slots in the hooks are interlocked, making 
their connection / disconnection easy. However, any connection system 
that is safe may be used.

2.5.2  CHANGING THE RISER CORDS.

In spite of the speed system having pulleys with bearings to reduce 
friction to a minimum, the frequency with which the speed-bar is used 
causes the cord to wear and you may need to replace them.

In all Niviuk gliders the speed system cords on the risers are completely 
removable and easily replaceable.  You can use the Brummel hooks, not 
use them, remove them, use another type of connector, etc. It is even 
possible to fix the speed-bar cords directly to the speed system on 
the risers. This last option makes the connection / disconnection more 
laborious, but means the cord has maximum travel without obstructions 
or restrictions which is very useful for some models of harnesses.

2.6 INSPECTION AND WING INFLATION ON THE GROUND

After your gear has been thoroughly checked and the weather conditions 
deemed favourable for flying, inflate your IKUMA 2 as many times as 
necessary to familiarise yourself with its behaviour. Inflating the IKUMA 
2 is easy and should not require a great deal of physical effort. Inflate 
the wing with a little pressure from the body using the harness. This may
