Newbie questions
While not new to bicycles and bicycling, the C&V category still has a few "mysteries" for me.
One thing I was not at all aware of is whether or not road bikes from mid to late '80s would have had springs on the QR shafts? Mine has none on front or rear wheels, but then I am at least the third owner of the bike, so they might have gotten removed at some point.
Were these standard with quick release wheels at the time?

Pretty standard as far as I know but you can get by without 'em.

+1 on not totally needing them; as far as I know they have a centering effect when you put the wheel back on. The QR is supposed to have springs for each end, though. Stay in the C&V zone long enough and you'll build up a whole bin of quick releases.

Already had a small bag of these conical springs from other projects, so will throw some on now knowing they were even used "back in the day". Thanks!

Next puzzling item ..
What on earth is the little projection off the right seatstay? It was welded on, so probably required some strength. Seems like overkill for a reflector mount, and if for racks or fenders, there should be one on the left side as well.
This particular model seemed aimed more at "everyday" riding vs "racer", so I'm imagining the point of this appendage is more functional.

The projection is for hanging your chain on when removing the rear wheel.

You can get by without the skewer springs just as you can get by without drinking decent beer.

These must have fallen out of favor later, maybe for the endless pursuit of weight reduction? Checking my steel MTB from ~10 yrs after this bike, and it did not have this.

I could be wrong, but I think the introduction of slant parallelogram derailleurs kind of rendered chain keepers irrelevant; in that the tension could be relieved by pushing the jockey wheel, rather than taking the chain off the gears.

Springs are worth having. You can get a bag of stainless ones on that auction site - cheap, though shipping may be dear.
Springs are fiddly things to make, and QR ones are special, a conical helix made of flat strip. They often get mashed or lost, so it was a happy result to find them available. What I'd like is a source for the little springs under the plastic wingnut of Simplex QR nuts. They are getting old enough that the plastic is starting to crack and fall apart, and then they fall off and the spring does too. Replacement wingnuts cast from epoxy are easy enough, but *that* spring is essential.

When I purchased the wheels for the De Rosa, I had a discovery about one spring.
The hubs are Record in black with black skewers. I was having some problems with the clamp side of the rear hub.

There were two springs stacked! pulled one out of the clamp housing and everything worked well. It was a bit mangle.

there primary purpose is to assist in mounting the wheel by spreading the open position enough to clear the DO when mounting. I know, kind of obvious.

Anyway, now that I know these springs were used even "back in the day", the wheels have a full set! As others have said, it does have a "complete" feel to it.
And I think I'll fight any OCD-like tendencies to get caught up in whether or not black would be the correct spring color for c1987.

"Chain Hanger
Some bikes have a small brazed-on peg facing inward near the bottom of the right seat stay. This is intended to support the chain when the rear wheel has been removed for some reason. This is, in practice, a pretty useless feature."
I don't know yet. Seemed like it would be handy at least to keep the chainstay a bit cleaner. Will have to try it next time.

Bring back the Portacatena!
Edit: geez, I just noticed that frame has a chain hanger and portacatena. Talk about belts and braces!

After getting more curious, I searched and found Sheldon Brown had some info. Seems he would agree on irrelevance of chain hangers ...

In my youth a chainhanger was considered a dividing line between cheap and better frames. Of course I'm 65 so take that for what it's worth.
