I only know of Pedalsoft that produces them, any other alternatives? I have winged handlebars and need a "clip onto stem" ability - any suggestions?

Thanks,

It's also nice since it won't void the warranty of the carbon handlebars.

Profile Design's Lightning Strike. I've never used them, a friend had them put on his bike but I haven't seen him in a while. They do need a profile design stem (distinct shape to grip on to).

I've got a set of lightning strikes and they work well. They don't completely block the tops of my bars, but the armrests do reduce the amount of area that you can use on the tops.

There really isn't a "perfect" shorty aerobar system out there. Oval makes the best, but it needs wing bars and a special stem, which is only compatible with 26.0 bars. And, shockingly enough, the only 26.0 wing bars are sold by Oval. And they cost $300. Here's a write-up on the Oval system if you're interested: https://www.slowtwitch.com/mainheadin...r/shorty2.html

The Jtek. You need a thomson 10degree x4 stem though

Oval makes some that clip onto their stem as well... Slowtwitch does a nice review of the system with aerobars.

I ran some bars many years ago, with a name something like "shark bars". They were made of magnesium, and didn't like collisions with cars. They fastened to the stem with a pair of u-bolts, but the armrest pads each clamped to the bars, so it may not be quite what you're looking for.
