Bending Bullhorns Inward
I saw a messenger in NYC today who had bent his Profile Airwing bullhorns inward, making the total bar shape more triangular than rectangular. I want to do this to my Profile Airwings because they are quite wide and I'm afraid of snagging in tight traffice.
I asked the guy about the process for bending the bars. Basically he said he used a torch to heat them up, but not too hot since the metal is aluminum. Then he pressed them on the ground to bend to the correct angle.
Has anyone else bent their bullhorns inward? Any tips for tools to use, problems to watch out for, etc?

hello
I always wondered why bullhorns aren't designed in that fashion. It seems like a much more natural position for your hands to be in. I posed this exact same question about a year ago here, about bending bars.... Got a lot of negative responses.
I have one-piece mtb bars (w/bar ends) that are shaped in that exact way....but of course, these bars are way too wide.

The bars will then have the physical properties of a beer can.
Never, never, never heat any aluminum part on your bike with a torch, and never, never, never shake a baby.
Enjoy

The airwings on my bike have one side bent slightly inward. This happened when the bike dropped on the same side two or three times. So maybe you could just drop your bike on the horns a few times or get something to slowly apply pressure to them. Granted it wouldn't be much and you might compromise the strength and integrity of the aluminum...

I would put one side in a vice, hold on to the other side and lean back with your weight. Repeat for the other side.
If they break or you fall, I'm so not responsible. Good luck.

If you do heat it up, you could always re-heat treat it to its original T6 condition.

There is a pet crematorium down the street.
So I asked if I could throw in a couple bars with the next run of stray cats.
The guy says 'sure'.
Well when I opened the box there weren't any cats in it but there was a 60 foot sea monster from the paleozoic era...it was the loch ness monster...I said 'g**da** monster, what do you want?'...well you know what he said??
He said "I need about tree fiddy"

There's your problem, crematoriums run at over 2000 F!
That Loch Ness thing almost sounds like the lyrics to an RL Burnside song.

All of this advice says that it can't be done. I've seen a number of bar modifications like this before. Hopefully someone out there has advice not involving funeral homes.
Maybe I should just eat some spinach and bend them by hand.

Bad scene, dude.
Do it with heat and you anneal as mentioned. On the other hand, alu is prone to snapping. It can't be cold set the way steel or ti can.
And they're not this shape to begin with because it puts the arms across the chest which constricts your breathing. Not what you want in a TT or pursuit.

You can go to your local metal supply place and get some AL welded. I have had things such as this done for the Jeep. AL is hard to weld, so you'll have to pay out the nose ring.
Or you could get some lightweight tubing and have that bent and all.

My cheapo chuck's bullhorns are bent inwards. I always found it a little tacky looking. I guess it's functional though.

I'll disagree, welded AL if done right, can be decent. But very few will even try.
