Trying to find a nice bar and lines set for a racing / light wind use and I stumbled across this thing. Less than 0.5 Kg with lines, has a huge throw, different kind of way to depower. Still has the front line flagging depower system.

What do guys think? you won't be doing handle passes with it... but looks great for travel?

The bottom shackle piece you could replace with something else pretty easily.

Still not sure how that front line safety works.... If the line is threaded through that PU sheath, it looks good but how do you re-thread it.... or does the sheath fly up the front line leaving 1 line attached?

Go to any sup shop.
Ask them for a carbon paddle offcut

Drill holes in it

Put lines in


...

I remember when flexifoil was making hadlows kites and they came with carbon bars. People were snapping the carbon bars in half when doing handlepasses and getting ridiculously painfull long strands of carbon splinters and just sliceing theyre hands up..... So much blood... And just god damn painful.

Couldnt pay me to hold a bar that was made from glass or carbon fiber

Now... The right piece of hardwood on other hand maybe something reliable like a wooden baseball bat or cricket bat could be a pretty hilarious addition to the kit bag. No wind? Just start wacking cars and throwing people out of them and drive until its windy again

Really smart depower system. Im building some bars at the moment and I might pinch that rear line depower idea.

Looks like the cabrinha design. If so, the main centre / trim rope will disconnect allowing the bar, pvc tube and 3 lines to slide up while one thin line stays connected to you.

The cabrinha pvc tube is pretty unique, it is divided down the centre into two hollow sections. On one side is 5mm rope and on the other side is 1.3mm flagging line. That way there is no risk that the two get wrapped up and stop the release working.

If anyone knows where to source cabrinhas pvc tube in long lengths let me know!

So how do you re_engage it once engaged ... is it possible ?

Yeah you just slide the bar and pvc tube back down the flagging line until you have reached the stainless ring that was connected to you and your harness i.e. resetting it again. Not difficult, at least on cabrinha and I'd say this would be the same.

Google some pictures of the cabrinha trim lite bar safety release and you'll see what I mean

Anybody know exactly how the back line trimming system works?

There's a vid on the website. Wondering if you get some sideways load on the bar say after a crash it could inadvertently change the back line trim setting ? Looks nice and simple that's for sure.

Probably works on a little cleat. Looks like a nice simple idea.

The current crop of bars that have enclosed depower and safety lines have a two chambered PU tube. (Cabrinha, Liquid Force, RRD I think). I can't find anywhere to buy that, except to buy a depower system as a spare part. A few years ago there were some bars that had both lines down a single tube. I assume that would work fine ... until it didn't.

The videos of this bar are clear enough to see a clear plastic tube and at least one thick line in the middle. I cannot see a second safety line in any of the pictures or videos.

The knots lock into a slot in the end of the bar. That's fairly obvious.

What happens inside the bar? How do you get both sides to move in and out equally? The knots go into the bar but they don't come straight out again and the line with the knots is thicker.

There has to be a little black magic happening in the centre of the bar. I can think of a couple of options. I wonder what it actually is.

If the knots slip it's just going to let the back lines out and depower the kite. That would be annoying but not much of a disaster (unless you're trying to water start and ride away from an approaching wave).

the chicken rope
the vert rope thru the bar

the trim rope
the horiz rope thru the bar

these two ropes touch at the hole in the bar
wear on the hardware
bad bad bar

I've asked the maker how all this stuff works (including a question about the hole through the bar) but he hasn't replied yet.

I like the simplicity and innovation of the system. I like the apparent quantity of information available on the web site. I am a bit concerned that all that information doesn't actually say very much useful.

To an extent that "show lots but say nothing" thing is endemic in the kitesurfing industry.

maybe the interior of the bar is split in two longitudinally
with one cavity solely for the trim rope

Two Amsteel/Dyneema lines running inside a single-core tube beside each other is a disaster waiting to happen.

Low-melting point means the lines will just rub through each other...

I think the trim system inside the bar would be similar to this patent from Best back in 2011 patents.google.com/patent/US8398030 . This might help you with your ideas dachopper and Macster.
