    Name that frame! Early 70s

    I am still trying to ID this frame. I just started ripping into it and I would love to know what it is when I get done. The bike has a mix of Dura-Ace and Campagnolo parts from around 73.

    Seat post is 27.2

    BB is 37x24

    Serial number is 052 located on the left side on the BB shell

    Headset is a EDCO

    Dropouts are Campagnolo

    that would have to be 36 x 24 (Italian) and looks very nice but:
    very unusual for an early '70s Italian to have under-BB cabel guides and all those cable stops... the braze-on shifter bosses might just squeek by as
    "period correct", plus they seem interesting given the round [is that early Shimano 600?] rather that square elements on the tube.
    Interesting fork crown too....too bad I got no idea for you!
    With all this unusual-ness I am tempted to call "American Custom Builder".

    Shifters were Dura Ace.

    Just checked. The BB is in fact a 37x24 Shimano

    Also noticed the front drops are Campagnolo also

    OK so that's 1.37" x 24...not Italian but regular Brit-enese. I didn't know that DA used the weird bosses that are usually associated with early 600...or are those not part of the braze-on but just the slide-on elements that came with the DA shifters? can't tell from the pic. Still can't ID it, but won't be looking under the "Italian" category.

    ^sure could be, but since it has a "52" on the shell, one would assume it's from a small-output builder who built at least that many frames (and the craftsmanship looks better than a hobbyist would do). There's something about the forkblades that look a little more "531" than "Columbus" to me...also appears that the chainstay bridge is an oval tube (longways up) and not a standard round tube.
    BTW: as to the age of this, in spite of the long Campy DOs, and the cable stops I don't think this could be an early '70s frame...even if there are later-added bits (like the shifter bosses and under-BB worm tubes) the seat lug and forkcrown both look like IC items...I'm guessing a mid-to-late '70s vintage, could even go to very early 80's from a custom job.

    I have found a couple of pictures of Proteus bikes but cant find anything that looks like this one. Should be on the road next week if all goes well.

    If by "cheap" you mean $50, then just contact Robbie Fellows at rnitro1969@aol.com
    he's taking orders and homebrewing a batch right now...it's cheaper if you can get an order of 3 pair together, so ask your friends.
    Otherwise, it's the old EAI greasy hoods from various sources.

    Some design features are similar to my Witcomb USA which I had built around 1976 or so.

    I was looking at a set on Ebay for 23.00. Are those the EAI? I am still new to this.

    Affirmative. You will be much more satisfied if you get Robbie Fellows' repros, or else find a set of Modolo 919 or 920 hoods on eBay -- they fit perfectly, and I like the “anatomic” ones better than original Campagnolo. Suntour Cyclone/Superbe/Sprint would fit too, but you almost never see those.

    I'm pretty sure this is an early 80's frame, not an early 70's frame. That's about when shifter bosses were brazed on. The 70's had clamped-on shifters and clamped on bottom bracket cable guides.

    From what I can gather from Velobase the Shifters are first gen Dura Ace sold from 73-77 as clamp on or Braze on. The crank is a 172.5 Dura Ace and those were available after 75. Thank you for the help with the hoods, I am gonna keep searching.

    I think it's an english bike because of the rounded over seat stay tops, posibly some kind of raleigh. Or, it couls also be a Motobecane.

    I think common production bikes have been narrowed out.

    Although braze-on shifter bosses were not common before the late 1970s, they were nonetheless available long before then. Campagnolo catalog #13 from 1955 shows them as part #660 on page 19 (actual page 19 or page 21 of this pdf of the catalog): http://www.campyonly.com/history/cat...catalog_13.pdf

    AFAIK, the under-the-bottom-bracket cable tunnels did not appear until the late 1970s.
