    Apples & oranges

    Hi Kris

    You might get better info posting that query in the Bike & Frame Discussion forum in MTBR - Bike and Frame discussion -

    That said, it seems to me you're talking about apples & oranges, as in those are two completely different bikes/frames that serve completely different purposes.

    What parts are you thinking about moving from the Trek to the Iron Horse? And what sort of riding are you planning on doing? It's unlikely that anything on the Trek other than the drivetrain would stand up to DH riding for very long.
