mine you it is columbus steel so it is stiff and built to last.
the new carbon frames might fatique after a while.
great builders like Cervelo brag about their strength tests so that has to account for something.
many won't stress a frame like Thor can so normal wear shouldn't be an issue but my brother's aluminum Trek did crack at the headtube.
frames do come with warranties so check that out if you are a heavier rider.
Actually, a well built carbon fiber frame will out last a steel frame. Carbon has a much longer fatigue life than steel. I know of carbon frames with over 120,000 miles and they work the same as if they were new.
However, I have heard that 80,000 on a well made steel frame isn't a problem.
