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.
