Sounds like a good idea to do some more testing...great place to do it as well!

Not trying to discourage you - the Dynabar is so much better than a fixed hook, however....

There has to be a better way than extending the rope even more forward and away from the body - with eye bolts and shackles - as shown on the top and bottom photos. Which make it more clunky!

Having the rope go through the hole (as in the middle photo) is the best for performance. The problems being that the rope has been breaking (on the V8) and isn't visible to inspect. However this didn't seem to be a problem with the V7?

Re-tensioning the rope needs to be addressed.

If the rope went back through a hole in a composite carbon fibre bar, which would be thick enough to not cut the rope - like the stainless steel bars have been; and went back to an integrated cleat on the back of the bar - that allowed visible inspection and easy re-tensioning....

Maybe this could be V9?

The D link system offers more than just geometrical freedom of "swivel and pivot" .

It also reduces stress on the Dyneema by completely eliminating "any sharp angle" out of the equation.

Anchored directly from one side to the other with the only curve at the pulley is simplicity with a low maintenance and long performance life = lowest cost and more time on the water .

I'm following this thread with interest, and am about to replace my dyneema (and grommets if possible).

I'm happy with my V8, using the dyneema slider, but the grommets have deformed a little (not split or broken), and there appears to be the start of fraying of the dyneema.

I'll probably incorporate whatever comes out of your testing to be the best/safest option, so I'm just wondering how the tests went.

Thanks

I was wanting to try a sliding hook setup with my seat harness as I was really struggling to ride toeside.

So I started making my DIY alternative when a V7 Dynabar came up on ebay for $70.00.

My setup only came with the lace/rope, which was a little stretched, making it very difficult for me to reach my above the bar depower. Once I added another knot into the rope and shortened it a wee bit I have never looked back.

I am really digging the Dynabar and like many others cannot see myself going back to a fixed hook anytime soon.

Now the cheeky bit.... I would like to try the freeride and prowave bars but don't want to buy them then decide I prefer the rope. To that end does anyone in Melbourn have one I could borrow? If I like it I would buy it from you if you wanted to sell it. Thanks

Ok got the sliding hook on the metal slider and im finding that my chicken loop will come out sometimes in really strong movements. Like relaunching or self launching particularly. Has anyone else ever had this issue? I have a core sensor 2 bar and im not sure if my chickenstick is supposed to be able to move 90 degrees from where it attaches. I cant remember if it was fixed at the base before and thus is the reason for the problem now. Seems like it?

The contact surface between roller or pulley is very small and
the roller slides instead of turning. There are also bending areas who are not completely smooth.
We tried harder delrin glass loaded but it wears more quickly.
The rope works better because it creates an angle and increases the contact with the pulley who is designed to have max contact surface.

Ok I see what you mean now, maybe a roller with groove for an 'O' ring so it can run along the slider bar and drive the roller so it rotates without sliding.

Also a 'lead in' (30 degrees) so roller still takes the load on hard surface with 2 contact points.

See my design for new roller, let me know what you think and I can do a fully detailed drawing if you want, I just don't have access to a lathe atm to make one and try myself.

You have probably tried various designs... just my 2c

We will give a try, thanks.

Meanwhile we have finalised the "Greenarrowz solution" and you can contact Kitepower Australia for availability dates.

Sounds like the goods....
I been using my original for months now with no complaints.
Would jaystore consider sending me one out for testing? ?
I have a idea for a micro rachet rope adjuster in mind.
