Here is the truth.

A bicyclist who buys a carbon fork, wants the lightest fork; otherwise, he would choose a nice steel fork.

First, he checks forks by the companies A and B.
A's fork: 50 grams lighter, but less reliable.
B's fork: heavier, but more reliable.

Then, he finds a fork from the company C that is 150 grams lighter. Of course, he buys this one.
