Inspect carbon fiber parts frequently
Unlike metal parts, carbon composite parts that have been damaged may not
bend, bulge or deform; a damaged part may appear to be normal to a cursory
glance. After any high force load, like a crash, or other impact to your bicycle,
thoroughly inspect all the parts of your bike, and use the following procedures
to inspect carbon composite parts.
To check a part for surface problems (visual test)
1. Clean the part thoroughly with a damp cloth.
2. Look closely for problems: scratches, gouges, cracks, loose fibers (which will
appear like thin hairs), or other surface flaws
3. If the part has any problems, do not ride the bike. Take the bike to your
dealer for replacement or further inspection.
To check a part for loss of rigidity (flex test)
1. Use the part in a normal manner (without actually riding) while someone
watches carefully for unexpected movement. As an example, if you suspect
a composite seatpost has been damaged, sit gently on the saddle while
someone watches to see if the seatpost flexes.
2. If the helper sees the part flex unexpectedly, or if the part feels less rigid than
it should be, do not ride the bike. Take the bike to your dealer for replace-
ment or further inspection.
To check a part for delamination (tap test)
1. Clean the part thoroughly with a damp cloth.
2. With a nickel or other coin, tap the part near any possible damage, and places
where the part is known to be in good condition (or use a similar part).
3. Listen carefully for variations in sound, especially a hollow sound, “dead”
tone, or any sound indicating that the part is not solid.
4. If the part makes any noise other than a hard, solid tap sound, do not ride
the bike. Take the bike to your dealer for replacement or further inspection.
