scratch, or change of color in a high-stress area indicates that the life of the part
(including the frame or fork) has been reached and the part should be replaced. If you
are not sure if you should replace a part, consult your dealer.
In some cases, a lighter frame or part has a longer life than a heavier one. However,
better maintenance, more frequent inspections, and more frequent replacement are
necessary for a light-weight, high performance bicycle and its parts.
WARNING
A bicycle is subjected to wear and high stress. Different materials and parts may react to
wear or stress fatigue in different ways. If the design life of a part has been exceeded, it
may suddenly fail, possible causing injuries to the rider.
