I understand the enjoyment of collecting, maintaining, and riding old bikes, and how that becomes a hobby all its own, much like people who do the same with vintage cars, motorcycles, etc. However, what is unique about these forums is the belief of a vocal few that there is some equivalence in overall performance, or that, from a delusional few, old bikes are superior. If there were any validity to this, you would see demand for these old bikes from individuals other than collectors of the same demographics as the bikes.
