Fitting the speed-system:  

Most modern harnesses have pulleys attached for speed system fitting. In case not, it is 
important to attach pulleys (sewn on tabs) in such a way that they allows the pilot to 
maximize the power vector of his / her legs without ”pushing back” in the harness. 

The Yukon speed system, including Brummel-hooks supplied, must be assembled as 
per instructions. 

The speed system cord is firmly attached (use bowline or other nonslip knot) to the foot 
stirrup (webbing or alloy bar). The other end of the cord is run through a pulley on the 
harness and then in an upward direction to be then firmly attached to the Brummel-
hooks!  

The length of the cord leading to the stirrup should be adjusted so that it is easy to put 
your feet into the stirrup in flight but still short enough to allow full speed system travel. 
(Use of 2 stirrups in a ladder fashion can enable you to reach the full range if your legs 
are not long enough.) Ensure both cords on the stirrup are of equal length, to avoid 
putting a turn in the glider. 

Test your speed system for the correct length of cord on the ground first (simulating 
flying position), with your harness and risers, before flying with it! The full range is 
reached when the 2 pulleys join together. 

Before launch, attach the paraglider's risers to the harness with the main karabiners. 
Then attach the ”Brummel-hook” on the end of each speed system cord to the Brummel 
hook on the end of the cord which runs through the 2 pulleys on the A risers. Ensure 
that the speed system is untangled and operates freely before flying!
