Karsten, this whole thread is irrelevant and should just be closed now, based on the premise of your question. You asked why something matters... What "matters" about bikes is different to every single person who has posted in this thread. It may even be different to same person each time they post in this thread. The information that is useful to me may be archaic or overwhelming for you.

This is no different than talking about the (often shocking) fact that I enjoy riding a gaspipe rocket ring'd conversion EVERY OUNCE AS MUCH as someone on a phil'd/deep v'd/somethin somethin does. Enjoyment, just like the "need" for knowledge, information, acceptance, etc is different for everyone.

No more arguing the inarguable.
