Genius or potentially stupid .....(handlebar content)

Sooo.....for some reason my gravel bike had aero handlebars on it and after riding a buddies bike with flared bars I wanted to give them try.

After few beers I decided I’d try making my own with some normal drop down bars I had lying around.

What could possibly go wrong???

Worst case, the fatigued metal fails while you are riding and you crash facefirst into the pavement and smash out your front teeth and the traffic around you crashes into each other.

Actually, it could be worse than that...

Also, the way you have it pictured...the tops might bend at the clamp area. If you want the flare, you should make sure it only bends at the first bend of the bars.

If the bars were heat treated after bering formed you should not try and set them into a different position.

Exclamation

New handlebars are quite inexpensive.
I assume you are posting this as a joke.
You are posting this in humor, right?

What do you mean by troll post? Seriously.....

I shouldn't claim to have come up with the idea myself, as I stole the idea from someone else.

It's alloy......I've never in my life heard of alloy bars fatiguing to the point of failure.

Google told me this:

That certainly wasn't my intention. You can lock it up if you think it'll get too outta hand or cause trouble.

Cheers.

We tried something similar at work a few years ago.

It didn't end well but no one was hurt.

It won't end well and I can't guarantee that you won't get hurt.

While those stretch into the shape you want and you've got some time to kill, look up good oral and orthopedic surgeons in your area.

They came out decent.....very subtle flare compare to most flared bars that require you to turn your shifters horizontal

What you’re doing is extremely dangerous and you need to throw the bars in the trash. Those are aluminum and you’ve likely compromised the integrity of the handlebars by bending them like that. You can disregard me if you want but while I’m not an expert on metallurgy, I’m a mechanical engineer and I’m a little bit familiar with materials and you couldn’t pay me to ride with those handlebars. I’m sorry to break the bad news to you but for your own safety you need to get rid of those handlebars.

I think the general consensus is that bike alloys and aluminum is heat treated so that it becomes harder at the expense of being less malleable. I think this would really depend on what type of alloy your bars are made of. Did you check for any possible cracks where the are bent outwards?

For starters I would stress test the bars before using them on the road, i.e., stress testing them with at least your body weight, more if possible.

If this isn’t a troll post I’m going to be in Tempe for work next week. I’ll give you a set of handlebars if you promise to not even attempt to ride with the ones you bent. I’m completely serious.
