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.
