Just my non-technical expertise.

Granted I don't know much about engineering but I have been the end user of "plastic" (fiberglass and carbon) in both sailing and bike racing.

These are both very sophisticated products designed to have very high strength to weight ratios. In both cases Aluminum was only a fad. All high end boats very quickly went to fiberglass and now kevlar/carbon. And as far as bikes you would never catch me on an aluminum bike. I went from Steel to Ti to Carbon and skipped aluminum due to fatigue issues while racing. Granted a good bike will cost you $4,000+ the difference between a good aluminum and carbon bike is not that much different.

A Ti Airstream would be very cool. And very, very expensive. But my Ti mountain bike still looks brand new even though it's 16 years old with about 50,000 miles on it. Well the Ti frame looks brand new, every other part has been replaced several times.

Yea, I have an 8 year ti mountain bike, but far less miles. That bike looks great (to me a little retro for others) and was well worth the investment. Light, flexible and strong!

But my road bikes are carbon allowing a 18 bike to go to 15 lbs. Big % change.
