The Lifespan of Your Bicycle
& its Components

cont’d

you fit the “lengthen product life” profile, the more likely it is that lighter components may be
suitable for you. Take these choices seriously and understand that you are responsible for the
changes.

A useful slogan to remember when contemplating changing components is “Strong, Light,

Cheap — pick two”.

Original Equipment Components

Bicycle and component manufacturers test 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 wont.
