What is this?
Got my old Trek road bike on the stand for a cleaning and to replace cables. Took a good look at this fitting on the back of the head tube while it was up and still can't figure out what it is/does. Anyone? Just curious. Thanks

I have seen them on several bikes. I have never known what they were. My steel Burley tandem has one.

Stud for some types of frame mounted air pumps.

It's a pump peg
It's a pump peg for a frame pump that mounts under the top tube.
The Zefal pump has a hole in its end to capture the peg, and the pump is held in place by the compression of the spring inside it.
Maybe the old Campy pumps have the same mounting hole, but I've never owned one.

The only thing you have to look out for is finding a frame pump that is the correct length to fit along under the top tube. I own 4 Zefal HPX frame pumps in different lengths for just this reason

Hi guys, just to be clear, I hope I didn’t come off as snarky or mean or anything like that.
It was more an exclamation at/of/over their cuteness. Like when my niece found an old rotary dial phone at my parents’ beach house and couldn’t figure out how to use it lol

So I’m on the phone with my girlfriend shortly after I hear about Lou Reed’s passing. I tell her something like I can’t believe he’s gone. She’s a little bit younger but will be thirty in May. A millennial but I’m thinking she knows who Lou Reed is.
She goes, “Lou Reed? Who is he? One of your friends? I’ve never heard you mention him before.”
Lol!

As other people have noted it's a pump peg for a full size frame pump.
You want a full size frame pump because it will get 700x25mm road tires up to riding pressure in 90 strokes. Unlike CO2 cartridges, it can't run out if you help another rider who flatted or get a slow leak you can't find from a piece of tire wire.
You can use a short strap to keep it from rattling or falling off on a humongous bump.

No, I thought it was cute, however I wasn't exactly sure what it meant. Most of us here are gen x and boomers I thought.

I'm sure I've told this story before but it always a good one. I was making a delivery in one of our campus's older building just before renovation. It had housed one of the first cyclotrons in the country,so it clearly was due to be renovated. But while walking down the main hall off the building I heard a student exclaim "Wow, they have special booth marked telephone that I can go into and have a private conversation on my cell phone! As you can imagine any traces of a phone were not in the old cabinet. Smiles, MH

Those old phones come in handy. During the last hurricane here in Miami (can't remember the name I've been through so many), the power went out but the telephone lines were still energized, they are on a different grid, and I was able to make calls. It was an antique rotary phone that I bought as a collectible, probably from the 40's, but it worked great.
