Steel and titanium only fatigue if loads abnormal (possibly unheard of) for cycling are placed upon them. Where aluminum fatigues at any load level, ie. every pedal stroke contributes to the frames death. As for the "all metal frames fatigue and eventually fail" statement, that is not a realistic view to take. How long are you going to live? Steel and titanium are going to outlast you by far, and titanium will outlast your children. I have a freind who rides a penny farthing it is 110 years old, and it is still used for training. She won the 2002 high wheel world championship in Belgium, I don't know if that was her competition bike.
