But how can you test the bar is you have to destroy it first?downunder wrote: ↑Fri May 08, 2020 2:47 amShort answer, yes.
Because none of this bars people are using are tested. Particularly DIY bars.
If used in a light wind, fine. But lets say it snaps and sharp pieces end up in the eye? Is it worth risking? I rather risk a snapped line or whatever.
I'm sure bike industry can afford testing...Just remember Ozone 'tested' a new bar release which ended in a failure. It can happen to the best.

It is totally impossible to run the test for each bar, so what some of us did is make one, break it, and then asume the other bars made in the same way will behave similarly to the one we tested.
There is more to it than saving weight for traveling.
You're just running a straw man argument downunder. Where are your tests of alloy bars after saltwater exposure? You're making an issue out of nothing.downunder wrote: ↑Sat May 09, 2020 1:51 amNot really no.juanpasala wrote: ↑Fri May 08, 2020 8:25 pmBut how can you test the bar is you have to destroy it first?downunder wrote: ↑Fri May 08, 2020 2:47 amShort answer, yes.

There are tests and tests. No one needs to do a destructive test.
One example, got new race lines. Snapped it near loop on first usage.
If I've put a 50kg load on that line before first usage, it would probably snap. Destructive test is 500kg of load, and more.
I did have a long discussion with MattV about using carbon in my builds:
viewtopic.php?f=107&t=2382042&p=890031& ... lmet+build
So helmet is a good example, one hit and it will be compromised. Same as any other bike helmet.
Again, silly comparison with carbon WS booms (masts). We just do not drill huge holes on them Look at the above pic (just an example), make a proportional hole in WS boom, and than report back
So, go for carbon, by all means. I am using DIY carbon helmet, but WELL know the consequences. It's $5 build, right?
Carbon pump? It's been done. Sitting in my garage:

Nobody has come to this thread with copious reports of carbon bars failing yet there are plenty of reports of alloy bars and other alloy components failing. By the way holes are drilled in windsurf booms to make them adjustable. I have also sold carbon windsurf booms over the last 20 years and guess where a lot of them broke, at the alloy mast connection!
And as another example alloy masts for windsurfing were discontinued a couple of decades ago because of their failure rate compared to carbon composite masts.
You can be sure that manufacturers of kite bars for OEM companies will be looking to produce carbon bars as replacement for alloy ones, and just like mountain bike carbon bars, once the manufacturing volumes have reached scale they'll be the same price and we'll wonder why anyone would use alloy bar which corrodes.
