Has anyone made their own "Pro Tune" speed system? I broke the speed system and some bridles on my 9m Chrono V1 the other day and I don't feel like spending any money on it :) I found the dimensions in the R1 V3 manual:
PA1 590
PA2 460
PB1 980
PB2 530
PB3 200
PC1 540

I'm assuming that includes the adjustment knots. Failing that does anyone have the "stock" dimensions for the original speed system, they're not included in the bridle check chart.

I have made a jig with the intention of making a Pro-Tune Speed System, but yet to make a start. I opted with the pig tail extension at this stage.
Not seen any dimensions for the original speed system.

Yeah I sat down to do this now and I can't decide on what those dimensions mean. e.g. PB3 is connected to a pulley, is 200mm measured from the loop to the end of the pulley? Or maybe the top of the pulley? Or is it loop to loop and then attach the pulley? Same with PC1. If anyone has a this speed system and could do a quick measurement I'd owe you a beer :P

I’m of the opinion that the dimensions given are the length of the bridle line “loop end to loop end” as you suggested, before being fitted to the pulley.
This may be of help with respect to the original speed system.
I still have the original “Sleeved Dyneema” bridle pulley lines that had very little use and show no signs of wear, having replaced and upgraded the pulley lines with Amsteel lines as recommended by Ozone.
Out of curiosity I refitted the sleeved dyneema pulley lines to one of my speed systems which had failed the “Speed System Zero Position check” and found that the speed system/bridle connection point aligned perfectly. With that in mind the original “ Sleeved Dyneema” lines dimensions presumably are as they were from new and measure as detailed.
PB1 (995mm) was measured loop end to loop end without the knot with PB2 (440mm)measured the same way without the pulley. Just a question of making PB2 880mm sewing the loops as shown.

I have made replacement PB1 and PB2 pulley lines for one of my Speed Systems in which the A, B & C connection points line up within a couple of mm.
I have used Liros DSL00 2.4mm 600kg Sleeved Dyneema line in the interim, but may replace them later with Amsteel type line.
A tad fiddly when inserting PB2 bridle line through the pulley as it’s a tight fit but achievable.
Will check the condition of the line for wear and alignment to see how they perform. Will test it by flying it from the pigtails first and presumably I may need to tweak KR1 (Z) line.
Clearly a tunable solution as in the “Pro-Tune System” is the way to go.
