Dude, can you try harder to distort a discussion to make yourself look like a complete donkey? if so, please do ... it's hilarious.
Here is a Small point you may have overlooked (you may want to sit down before you read this): A bicycle is Not an airplane.
Shocking, no?
Now explain how the entirely-molded-from-CF chassis of racing cars are failing everywhere because they don't have titanium wing spars---which your steel and aluminum bikes do, right?
(Of course, a bicycle is not a car, either ... did you know that?)
What might work really well for a bike might Only work really well for a bike. Imagine that! Or, a material might be available for use in a wide range of applications, using its various properties in different ways ... I know you are en engineer and can understand all that.)
As I said above, honest literate folks can find a lot of accurate information about the various properties of various materials---which means when people say ridiculous things like you just said, honest, literate people can guffaw with hilarity. Thanks!
You have made yourself the poster child for the "People with raging antipathies against CF frames." Start a facebook group, gather your scattered forces, feed your absurd biases.
As I mentioned above, if I could find Ti for the same weight and price, i'd snap it up, because right now all I ride is steel and aluminum, and even with a CF fork and seatpost, the Al is a little harsher. Not in any way uncomfortable, but the steel frame is essentially a giant spring, harmonizing the road imperfections.
Well-made Ti seems to be the best combination of strength, weight, durability and comfort----better than steel, from what I hear. But I can't afford it and really (as you note indirectly) I Sure don't need it. As I said in a post above, for most riders the performance difference between a 14- and an 18-lb bike would be negligible to the point of being unnoticeable. Even more so for my, for I am a mega-clyde.
At some point the only benefit form a lighter bike (except in competition) is the purely mental benefit of knowing you have a "sub-XX lb." bike. it is like the ladies with their designer handbags, which are often ugly and are never anything but sacks with handles, same as the knock-offs, same as the cheapest crap for sale in a dollar store---but the ladies feel better because of that label.
For me, the "15-lb bike" is the designer handbag. Doesn't do the job any better, makes no difference except to a very few people, and is mostly a way to spend money of empty fluff .... and the all-important Placebo benefit (If I think it's better, and I think it makes me better, I can fool myself into being better .... at least in my own mind.")
The biggest benefit of building a CF bike: I can Still look forward to building a Ti frame somewhere much further on down the road. I can have my cake (my fantasy Ti bike) and still eat it (riding my once-fantasy CF bike.) Once I build a lightweight Ti bike, what's left to live for ... riding a bent when I am too old to bend over the bars anymore?
