Please...name this part. Help!
 

I am going to swap out handle bars on my Marin Argenta. It has a one piece quill. (I think that's what it's called. Looks like an 'L' and holds the bar) I am going to put on a Deda Aeroblue bar. So I need that one thing that comes out of the neck but isn't an L. It's just a stubby little piece that the Deda mounts on to.

Somebody has to know what this is called. Or possibly have one I swap/purchase? In any case thanks.

So, a road bike quill stem generally looks like a 7.

After that, I'm lost. Does the piece appear in this picture?

It kind of sounds like you currently have a stem for a threaded steerer...and are wanting to use a threadless stem... You'd need a new fork and a new headset if you're going to convert to threadless...

No, he's looking for an adapter.

OP, you can buy one for 10 bucks at Performance

...I always forget that those exist.

That's it! I've been looking online but not knowing exactly what it was called I couldn't find it. Thanks!!!!

No problem. Hope it works out for you.
