Fourth, I only hear sprinters fussing about stiffness, rarely climbers.
You could explain why would you "rather climb with a 15lb aluminum bike than a 23lb carbon bike any day" ?

But isnt bike weight different that rider weight? For example, lighter wheels means you ride faster, dont they? Or you are saying if I ride 5kg bike and weight 70kg, I will ride as fast as if I ride 10kg bike and weight 65kg?
