    DeRosa - Which model?

    Hello,

    I have found a DeRosa bike recently and am wondering what model it is?
    Maybe a Primato? It has no sticker which could help identifying it.
    The tubes are made of Columbus EL, has chromed headlugs and is equiped with
    Campagnolo Chorus.

    Better pics please.

    The usual, but importantly the bottom bracket shell, seat cluster, and fork crowns etc.

    Thanks, yeah, the bike is nice looking, unfortunately the seller didn`t take a or it in the last years
    so the condition is not so good anymore. He is the first owner, brother of a former professional Accacio Da Silva and
    coach of a bikeclub. You can see that the bike was used a lot at the time and unfortunately, as he told me, his dad used it
    in the last year to do some shopping or have drink. This means it was exposed to lots of rain.

    Whats with the Victory crank? Nothing. It is a Victory crank, not a chorus. Also The front hub is a Record and the Headset I think it not chorus too. But hey, that is not that important for me as it can be changed. The bike got riden, that is what it was build for and then it is normal to change parts after some time.

    Here are a few more and better pictures. I hope you can help me.

    I would agree that it is a Primato

    Congrats, it's a Primato...one of the most desirable and iconic later steel frames built (along with the MXL).

    I haven't seen many that don't have De Rosa panto on the seat cluster. The flat fork crown is also usually considered a bit more desirable.

    On the plus side, I love the color!

    EDIT - I just checked, and mine doesn't have panto in the seatstay cap either...apologies. Yours is pretty much identical to mine other than the fork crown.

    Thank you. Your DeRosa looks great too! And in much better shape!
    I think the DeRosa panto`s on the seatstay were only on the earlier models, or am I mistaking?
    Mid or end 80`s it changed.

    The frame of the red Derosa looks the same than mine. Only other decals. Maby they called this model only Primato in the US
    and not in Europe? What tube`s does it have?

    EL OS - as I believe all Primatos were (I know a member who thinks otherwise). The only differences I see are the fork crown and decals.

    Mine is EL, not EL-OS. Other than the Fork crown and that mine has both stays chromed there in no difference indeed.

    I remember reading somewhere that the Primato was not always called a "Primato" in parts of Europe because of the translation---for example, it means primate in German, not exactly evocative of a fast bicycle.

    I have a 1993 Nuovo Classico that has the panto'd seatstays. I believe that model hasn't changed much as it is, obviously, classic.

    The Sticker says Columbus EL. Does the OS means Over Size? Then your right of course!

    I don't think it's a Primato. There were a lot of other similar models(Endurance, Neo Pro, San Remo, Giro, to name a few) in the 90's. I would guess that it shares geometry with a Primato, though. Being a European model, would further complicate exact model ID.

    There should be a serial number under the cable guide, contact the factory and ask for ID.

    OS = over size.

    I will bow to roadrunner...and I have seen SOME of those features on some other De Rosa models, like the Cassanova, but, to my knowledge, none of those models used EL OS tubing. Euros might have a different name for it/decal arrangement, but I know that as the Primato.

    If recollection serves, and it might not, San Remo used brain tubing, the giro was TSX/SLX and the neo pro used genius.

    Yes, true as to tube types in US, but the Primato always had a flat fork crown, too. At least every one I've seen that was labeled as such. I have seen frames that shared every feature with the Primato apart from the fork, and have never seen a model name on them.

    The bike should clean up well. I would totally disassemble and treat with frame saver, for starters.

    I could swear I saw one with a sloping crown...either BBM or our friend in VA. I know squat about Euro models, so that could well be the answer.

    I know I was at a loss to understand why my Anniversary had a sloping crown, and it was suggested it was either a custom fork or a replacement for one that got lost in shipping.

    Hey maym036 - very nice score. It should clean up to be a great ride. Based on its history, I agree with roadrunner2012 that disassembly and some Framsaver or Boeshield is in order, but you already knew that.

    Too bad about the color, though. Everybody knows the red ones are faster.

    I know the color thing is in jest but I really love the OP's bike color, much better than red. What color is that exactly?

    That bike did not say 'Primato' anywhere on it, just like the OP's.

    Got it...I'm very interested to know what those actually are. When did De Rosa stop taking custom orders (if ever)?

    Kool Derosa!

    Measuring the diameter of the tubes will tell you if it's OS or not...!



    ><><><

    A good buddy of mine has a Primato sitting in his garage, an EL-OS. It's from the 90's & in like new cond. Replete w/ C-record Ergo. Another friend of our's gave it to him to hold onto cause his wife was a total nag about bikes & biking. They're both attorney's It was bright red. He never bothered to come back & reclaim the bike, so my friend had it re-painted Pearl White by Joe Bell & there it has sat for all this time & hasn't ridden it since......lol! I think it's 59 cm. I believe he had it painted white because he already had a red Merckx. I think I need to go bug him...

    I googled and found this: http://bikeadelic.blogspot.com/2011/...ato-el-os.html

    It is exactly the same frame and fork as mine. Even the chrome on the stays and the forkchrown. Only difference is the primato sticker and the pumpholder.
