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?

Quoted message said: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 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.
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.
