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.
WARNING: Do not ride a bicycle or component with any delamination or crack.
Riding a delaminated or cracked frame, fork or other component could lead to complete
failure, with risk of serious injury or death.
C. Understanding components
It is often necessary to remove and disassemble components in order to properly and
carefully inspect them. This is a job for a professional bicycle mechanic with the special tools,
skills and experience to inspect and service today’s high-tech high-performance bicycles and
their components.
Aftermarket “Super Light” components
Think carefully about your rider profile as outlined above. The more you fit the “shorten product
life” profile, the more you must question the use of super light components. The more you fit
the “lengthen product life” profile, the more likely it is that lighter components may be suitable
for you. Discuss your needs and your profile very honestly with your dealer. Take these choices
seriously and understand that you are responsible for the changes.
A useful slogan to discuss with your dealer if you contemplate changing components is “Strong,
Light, Cheap –pick two.”
Original Equipment components
Bicycle and component manufacturers tests the fatigue life of the components that are original
equipment on your bike. This means that they have met test criteria and have reasonable fatigue
life. It does not mean that the original components will last forever. They won’t.
