only be done at the factory. See your dealer for more information.

Modifying the wheelset (including hubs, spokes, nipples or rims)  in any way 

will void the manufacturers warranty and may be unsafe.

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.

WARNING

A damaged carbon fiber part can fail suddenly, causing 

serious injury or death. Inspect for damage frequently. If

before riding, or take the bike to your dealer for service.
