Composite frame, fork, and Component
Inspection
Cracks:
Inspect for cracks, broken, or splintered areas. Any
crack is serious. Do not ride any bicycle or component
that has a crack of any size.
delamination:
Delamination is serious damage. Composites are
made from layers of fabric. Delamination means that
the layers of fabric are no longer bonded together.
Do not ride any bicycle or component that has any
delamination. These are some delamination clues:
• A cloudy or white area. This kind of area looks
different from the ordinary undamaged areas.
Undamaged areas will look glassy, shiny, or
"deep," as if one was looking into a clear liquid.
Delaminated areas will look opaque and cloudy.
• Bulging or deformed shape. If delamination
occurs, the surface shape may change. The
surface may have a bump, a bulge, soft spot, or
not be smooth and fair.
damage caused by a handlebar rotating
and striking the top tube is common.
The resulting impact cracks and breaks
the top tube.
This is not a warranty.
The frame is not safe to ride.
Any impact or crash damage can produce
serious damage to the frame. This
chainstay was cracked in a crash.
This is not a warranty.
The frame is not safe to ride.
• A difference in sound when tapping the surface.
If you gently tap the surface of an undamaged
composite you will hear a consistent sound,
usually a hard, sharp sound. If you then tap
a delaminated area, you will hear a different
sound, usually duller, less sharp.
Unusual noises:
Either a crack or delamination can cause creaking
noises while riding. Think about such a noise as a
serious warning signal. A well maintained bicycle
will be very quiet and free of creaks and squeaks.
Investigate and find the source of any noise. It may
not be a crack or delamination, but whatever is
causing the noise must be fixed before riding.
