Bikes: Steel is real. All others need not apply.
I looked up the decal set that is on the bike and it is from the 70's. That's as close as it came. The front brake looks like a normal (aka long reach) which was available in the 70's and some 80's. The fork crown may be the clue to getting a better age.

Thank you for the link Ecrevisse, but I think I found already everything available about a derosa timeline on the net.
As for the campagnolo components that are build on it, they don`t help me much to find out the year of production of the frame.
The original owner told me that he bought the bike in 1972. I wouldn`t be surprised if it was a 2,3 years later. He was a rider, so with the time he upgraded the components to newer ones.
Gomango, as soon as I have finished the bike profile shots will follow. I first want to finish the bike. I am missing the chain, need to put gear cables and the right Wheelset.
If anyone could help me with finding period correct pantographed stem, Seatstay, brakelevers and Chainring that would be great. But I guess it is almost impossible to find some from the correct period which are also in mint condition.

We're all over the age of this bike/frame - it's an old thread.
I was in communication with Hilary when he was developing his timeline, which is not set in stone ...

Today I got an other DeRosa. I bought it from a former belgium racer called Stouvenaker. He rode a lot at the times to no wonder the bike got repainted with the years and components replaced by other.
From what I can see if I compare it with these (https://www.43bikes.com/derosa.html) bikes it should be from around 1972. He only could tell me that he bought it in the early 70`s but didn`t remember the exact year.
What do you thing, could that be? It has the 6 cut outs under the BB and heart cutouts everywhere. Fork also looks like the early ones without the heart in the crown.
The interesting thing is that the bike already has cablerouting on the toptube. That is very rare for that period on a DeRosa, or not?
What do you say?

Flat top fork crown, above the BB derailleur cable guides, exposed brake caliper mounting nuts, single water bottle mount(?) long horizontal slot rear dropouts(?), non brazed on top tube cable guides(?).....will point it towards an early to mid 70's era bike. I think most of the things I mentioned apply to this bike.

I just noticed that the Seatstay Cap Engraving has no heart in the O of De Rosa. This makes it defenatly a frame of the first version, no?
Too bad this frame is too small for me. I love my other DeRosa and wouldn`t mind having an other, even older one.

@Jet sancHez: Just was on the phone with the original owner. He confirmed me that the cableguides were like that from the beginning on.

The braze-on cable guides could have been a special deal, but De Rosa started doing them circa 1975, so it could also be gthat the bike is just a bit later than '72. remember that De Rosa was building lots of one-offs and pro bikes at the time, so there aren't "standard" features in the same way as with other marques. Those aren't the standard Campagnolo braze-on guides you start to see in the mid-70's, so think it's plausible they were a custom touch.

Yeah, that price isn't going to happen ...

25% of that maybe. There have been other early DeRosas on eBay in the last year or so, I also "look ever yday" as well.
It's an interesting bike but it's without original paint and decals. I hope you get your asking price but I don't see it happening.
also, what's up with the hole in the bottom of the TT to ST lug?

We are at the shop discussing this right now.
We are comparing it to a 1977 De Rosa a fellow brought in from the blue last week.
I may eventually help him post it around for grins.
Folks, lets just say there are some incredible examples out there still, so I really don't feel compelled to take many reaches.

There was a complete bike in original paint circa '73 or so that went for under 3 grand within this past year, if I remember correctly. Or if it went for more than that, it wasn't much more. I should have bought it. They do appear from time to time - and several nice ones with pressed lugs have gone relatively inexpensively in recent history.
I had a stunning '77 that I sold. Sniff. And for only a bit over 2K.

This one looks very nice, but may be overpriced. I paid quite a bit less for mine with original paint / decals and mostly original componentry (Campy NR/SR, 3ttt, down to the Selle Royal CX saddle..). It's a 1977 or 1978, though..and very similar to the bike Picchio Special had with the fluted seat stay caps - even more rare I believe.

Out of this world, if I am remembering the correct bicycle.
Feel free to post a pic. We won't mind.

I'll have to dig the pics out. They're on another computer. I'm more upbeat about the Colnago I just bought, which I may post pics of instead in their own thread, since I still own that one. That De Rosa was sa-weet, though ... just not able to be a museum curator any more, or I'd still have it. Rode great, too ...
