It would seem that if you substituted a snap shackle for the carabiner, you could have a backup quick release.

Hey Tom - Nice job. I´d suggest you try different lengths of the dyneema rope hence you can dial in your preffered length. The sliding movement is infact very sensitive to the length of the dyneema rope. To short, and it will feel very un-balanced.

Yesterday I used a climbing carabiner directly sliding on the dyneema rope. Worked realy well and was very easy to hook into the CL when self launching. It does stick a bit and the sliding is reduced but it is then a bit easier for jumping.

I also own the current Jaybar 2013 - really nice.

However, I realised last time I used it that the little "slider wheel" is not turning easily... not really an issue since the hook slides without the wheel turning (of course with much more friction and wear on the rope)- but is that how it is intended? I don't even remember how it was when it was new...

The pulley turns easily if the angle made by dyneema rope is <45 degree but normally it is >90*

I think I understand the trade off with line length. Short and it kind of tick tacks back and forth from either side 3/4 the way along so just off one hip or the other. Still give good range of motion for toeside but it feels a bit like it jumps around. Long and you start having the bar farther and farther away with more variability to where the sweet spot is. The slider will move a little more smoothly, but you are reaching more.

Anyone have any insight on what works best for them and why?

I assume fixed hooks are the equipment of choice because they were adopted from windsurfing. Just yesterday i was telling a kiting friend that once I tried sliding spreader bar hooks i will never go back to fixed hooks. Sliding hooks seem to be gaining momentum in the kite boarding community and I predict they will be the equipment of choice in the near future for most kite boarders.

I own a Jaybar and could not be happier with it.


I like when people is open to innovation, some are against but they don't know why!
You got the issue, fixed hook is inheritance from windsurfing and kitesurfing designers didn't start from scratch as we did.
Sliding hook is the future...

I admire your entrepreneurial spirit and applaud your bringing a polished product to market, but that last bit.... THIS is a forum. Your are welcome to advertise but no single thread is an advertisement and any attempt to make it so is unwelcome.

I would never have posted these without that post:

Here is a super clean super safe DIY version that is every bit as slick as commercially available products, cost is about $60. Mostly for the high end snap shackle that has a working load of 880 kg a breaking load of 1500 kg and swivels. Do your research on shackles. This is the safest option for kiting. Photos show minimal mods to a standard dakine spreader bar pad and can be done inside a half hour if you know what your doing. I run a dedicated short line wave bar as shown and a regular commercial bar for unhooking/fixed hook twin tip riding. Shorter QR set up than standard chicken loop + hook means less loss of sheeting range when using slider. Slider line and ring stow cleanly. Tie downs at bottom stop spreader bar from flipping and are tied through pad. Fixed hook does not interfere in any way with sliding system or its safety. Leash is to mini 5th or single line flag that is independent of sliding system should it fail in any way.

Tom, where did you get the pulley?

Starsky, well said.
Was thinking of doing exactly what you've done, don't want to cut off or ruin my existing hook.
