That steel and aluminum have different fatigue characteristics is what engineers would call "trivially true." Frame design and engineering expertise are what count. Multiple frame torture tests conducted over the last couple of decades have demonstrated that, among lighter-weight frame material categories, aluminum and carbon frames can generally be expected to outlast steel frames, internet lore to the contrary.

To the OP: enjoy that Cannondale. They're great bikes. I should have bought one when I was selling Cannondales in the '80s and '90s.
