I do have bikes that I am particular about everything being the correct and proper vintage, manufacture, etc. These are generally not bikes that I ride very often. The ones that really get ridden have acceptable (to me) interface parts, and I don't really care what others think about them. Saddles have to fit your butt. Pedals must work with your knees. Handlebar tape must be something that you can stand over a relatively long period of time.

You can always change those parts out if you have a bike show to attend...

Now, white tires...
