    This is big bull shit of course and I'm a Nag non believer.
    Racers and dealers say so, not only alu but also steel.
    People are looking for excuses to sell/buy new bikes, which is good.

    And oh yeah, Boeings and Airbusses do fall out of the air after 3 years service, because of reduced stiffness.
