  1. The first Specialized carbon framed road bikes, late 80s-early 90s
    looked groovy with the carbon tubes mated to aluminum lugs. One
    shop said there were problems with those frames, that they separated
    or corroded at or in the lugs. Has anyone had experience with this?

    thanks

    IIRC, "galvanic corrosion" between the aluminum and carbon was the
    culprit. In addition to Specialized, similarly constructed frames from
    Alan, Trek and others suffered from this. I doubt a used frame of this
    construction is worth much attention.

    I probably saw the same one you are looking at. I'd be leary of it, for
    good reason or not, just because of those joints. Other than that, it
    would be an interesting frame to own.

    I had one of the early Alez frames and put thousands of miles on it over
    17 years. The lugs were crusty from corrosion but no issues (and I weigh
    200#). A couple of months ago, the downtube shifter boss broke loose.

    I took it to the LBS I bought it from and Specialized gave me a brand
    new Roubaix frame (aluminum, no fork) as a replacement!

    I asked the LBS about the lug bond rumors and they had never seen or
    heard of one actually breaking.

    The Specialized frames, Epic or Allez, were especially notorious for
    their separation of the downtube and seat stays from the bottom
    bracket shell. Specialized replaced their share of them.

    However, they continued to make these for several years and, as I
    understand it, mostly work out their problems. I know someone who has
    a 1993 Specialized Epic which was his good bike for several years and
    about 20K miles. Today it serves as an awesome fixed gear.

    If you have one and really think it's junk, send it to me.

    I have a 1990 Epic Allez, which I bought new and have ridden since. I
    must have 20,000+ miles on the frame. Currently set up with 8 speed
    Dura Ace and Campy Chorus crankset. Yes, I spread the chainstays a
    bit to get the 130 mm axle in place.

    I don't see any sign (yet) of corrosion or separation. But I did buy
    a new '07 Specialized Roubaix this year. Partially because I wanted
    the additional bit of comfort. But also because I live in South
    Florida now and ride near the beach. I can't help but wonder if the
    addition of sea air might hasten the corrosion.

    I did notice the dramatic difference in "flex", meaning when I press
    my foot gently on the bottom bracket and observe the deflection. The
    new bike is much better. The SRAM Rival components just plain works
    also.

    I keep the Allez as a backup bike and for company to ride. Still
    going strong.

    Just my two cents.

    That's a good report all right. Do you have any idea how long they sold
    frames like yours? I have just never seen one before.

    I remember that the same frame was available the year before and after
    1990. I liked the decal colors better for those years. My decals are
    a reddish-rose color that actually has grown on me over the years.
    The other decals were yellow and really stood out against the natural
    carbon weave.

    I think the frame was new in 1988 or 1989. ??

    Sorry, but I don't know when this frame was discontinued. I believe
    it was still around during the mid '90's.

    I had a '92 or '93 Specialized that corroded as you mention. Specialized
    replaced it in early 2000's (I think the r.b.t archives probably contain
    a more accurate date). The frame didn't actually fall apart, but the
    corrosion was obviously visible around the seat lug and bottom bracket.

    get rid of it, and as a general rule nobody does much more than
    circumstances drive them to do. -Harriet Beecher Stowe, abolitionist and
