Milage before wear out
I am looking to get into road biking (I currently do primarily mountain biking), and I was wondering how many miles components and frames are generally good for before they start to show signs of wear/wear out.
I ask because I am looking at buying a used 2002 LeMond Zurich. The owner says that the frame has about 6,500 miles on it and the components (Dura Ace) have about half that much on them. With a steel frame, I was wondering it would start to wear out and/or flex.
