How to make 4:1 Trim System on 2020 North Navigator Bar

[JimmyRyder]

Hello guys,

I've been riding different bars throughout the years from Ozone to Sling, Cab, Airush, etc.

The easiest to trim were the Core (has a 4:1 ratio) and some other custom race-bars (also 4:1 ratio).

So on my new 2020 NORTH gear I would like to turn the Trimming System into a 4:1 on my new Navigator bar.

I know that beside the existing parts the bar is made of, I will need an extra longer line and one Slider.

The new Longer-Line and the Trimming Line will both be connected from the Loop on top end of the Depower Line (right at the cleat).

1) LONGER LINE (new line) - goes all the way through the Front Lines SWIVEL and back down - then the looped end will connect to a SLIDER.

2) TRIMMING LINE - will go through the SLIDER above mentioned line, then come down and through the CLEAT.

My questions are:

a) What type of line to use for the longer line (dynema, spectra, etc) ?!

b) What thickness should this line have ?! (obviously I prefer thinner but strong)

c) How long should this line be in order to not screw up the bar setting ?!

d) I know the Leader Lines should be replaced with longer once - How long should those be ?!

Thanks in advance for your input and help !!!

(this topic is addressed mainly to the Racers that actually did and know this bar setting please)

You only need to extend the rear leaders if you want a bigger trim range or if you are going to use a floating single pulley rather than fixed double pulley. Line required is dependent on cleat to be used, length is trim X no of runs plus desired handle (+ allowance for splice or knots).
