Anybody try these out? Would it increase the turning substantially or would a 55cm bar do the same trick as the below 46cm?




Not bad price for $90US.

Yes it will increase the turnabilty of a badly bridled and designed kite and you you develop tennis elbow and look like the incredible hulk

Hi Mr Float,

The pic is a bit small but what you are saying is that the bar pressure will be excessive, I suppose it would act similar to the 2:1 Bow kite bars but the pressure would be in the sheeting in out rather than the turning like the old Crossbows.

I had a 2007 Xbow and near the end of the season I could not kite for more than an hour at a time due to tennis elbow.

I suppose Southwind bar on a C kite would not be so bad due to not sheeting in and out as much as a SLE, especially a low aspect kite.

Still very curious about the turn ability, Top Hat swears by them but then his has no depower???

Cheers

It looks like it is still a 1:1 bar but the front lines are redirected away from the top center of the bar.
So bar pressure would still be the same as the original kites 1:1 bar.
The 2:1 bars have the pulleys on the rear lines.

correct it will still feel the same bar pressure wise as a 1.1 bar... its clear you guys werent around in the oldschool pulley bar days... but what a pulley bar does (like the one above) is it makes the central pivot point of the bar move around so when you turn right for example the centre lines shift to the left of the bar centre which effectively increases the length of bar you have for leverage, more leverage = more turning.

it will increase your turning speed quite a bit i'm interested to see how well the power/depower works because having a bar without any sh!t in the centre would be pretty handy.

Hi guys,

I still have my old Airush Pulley Bar in the shed at home. It has the single harness line with swivel on it. It's mint and if anyone want to pull big mans kite loops, I'll loan it to you to put on your "C" kite. It's even set up with 20m lines for serious kitelooping. I'll stand by with the camera

Pretty sure there are not too many people in the sport nowadays who could still ride a "C" kite with no depower, no safety system and fast turning of a pulley bar. It can only be setup as a suicide safety system. Pretty sweet huh?

No it's not for sale!

yeah i got mine sitting outside too, was thinking about cracking it out next time i go for a ride. that open centre is joy for doing grabs of kickers

Shows how the depower works. There must be a couple of little sheeves in the bar so the loop is connected to the pulley line.

There's 2 pulleys on the outside of the bar then the rope runs through the bar to 2 more pulleys in the centre.
The turning is a little hard to get used to because the main pulley jumps a bit as you steer. Its actualy better without the main pulley the 2 front lines run off but then the kite doesnt turn as fast.
There are 2 bungy cords that help the sheetout. If you let the bar go it doesnt automaticly sheet out like a normal bar. So without the bungies you have to push the bar to sheet out. The bungies only sheet the bar out part way too.

So its not suitable for beginners at all and takes a bit of getting used to.

You can remove the main pulley so it feels closer to a normal bar but still the problem is when you crash and let go of the bar without the bungies it doesnt sheet out.

The bar pressure is super light.

I playing with ideas at the moment to make it a bit more user friendly.

Just stumbled across a kiteworld review of the Southwind Pulley bar. They tested the bar on a 16 m North Rhino as well as an 8 m Ozone Instinct Light.

Rather than me tell you about it you can see the review on issue 41 of kiteworld, page 108, which is available as a free digital back issue on the web.

removing the pulley from a pulley bar.... why dont you just keep the normal bar... if you want to slow it down a bit you make that V coming from the bar ends to the centre pulley longer, if you want it faster make that v shorter. if the pulley jumps its probably ** quality and just needs some good lube, the whole point of the pulley bar is for the centre lines to move as you turn the bar.

Charl DV,
You cant realy make the V longer because its part of the sheeting system.
So as you sheet in and out it extends and reduces the length V above the bar.
The other point of the pulley bar is not have the centre line running through it.

Just had a look at the pulleys and used on the southwind bar and they are all good quality Ronstan pulleys.

Fluid,

Can you take some detailed pics of your bar?

I would like to see how the pulleys are done, etc.

Cheers
Rich

as Charl said the length of the v line changes the kites turning speed. So a sheetable pulley bar would change turning speed as you sheet. Haven't tried this bar but this seems wierd.

Made a pulley bar years ago and used it with '04 fuels when the wind was steady. Good fun but never liked it when it was gusty. Also found it wouldn't stop turning after a stack on suicide. Still have it somewhere. Needs a new swivel harness line.

Hey rich (& others)
Woodys has a demo 'sheetable pulley bar' on the way. I'll post here & pm you soon as it arrives.

Interesting concept. I was actually playing around with pulleys and bars back in 2005 trying to achieve this same result. I gave up when bar diameter became an issue. Pulley bars took away all your depower (what little you had back then) but made my 15m Fuel turn like an 11M.

you can make the V longer, you just need to adjust your back lines to compensate. basic tuning required. PS i was referring more to standard pulley bars but it will work on these as well.

On a standard pulley bar agree.

On the Southwind sheet able bar, when you are sheeted in the V is long and when sheeted out the V is short.
It is possible to just pull on the depower though but the idea is that you can sheet out when you need it then it gets twitchy.
Im playing with the Southwind bar at the moment so will see what i come up with that works well, havent had alot of time yet though to busy working on the 2012 kites.

should be riding pulled in to max power anyway make a vid of it in use, could be interesting
