Maybe there's a new frame material out there....2 D polymers "as strong as steel, as light as plastic". (and made of plastic, actually)

Who knows whether its stiffness and compliance are optimum. Somebody is bound to try it and find out.

Flax is the next big frame material. Trust me ...

Commercial carbon fiber has a density of about 1.8 g/cm^3, plastics vary from maybe 0.8 up to 1.3 g/cm^3, so there should be a weight difference per volume. Of course, carbon is *stronger* than steel, and so it's hard to say how this will play out......if at all.

Ti is the best steel so the most real *but* cost always determines the outcome.
Stronger, lighter, and does not rust or crack as easily as the other choices, just need to pay +$
Same case for using grafil or now flax as a dampener or filler, just made manufacturing too expensive.

In other words, it was a joke.

Carbon bottle cages tend to be lighter than plastic ones of similar strength. About half the weight actually. Obviously less material required with carbon.

I'm not going to argue the point, because we're talking about a material that isn't yet a commercial product and may never be, but you are talking about plastics that are presently on the market, and that's not necessarily indicative of what this new super-strong material could feasibly yield.

I do not recall Ti being ever used to iron faces. Steel and Carbon for shafts, too. I do recall aluminum shafts in the early 70's. Ti? Not that I remember

"Carbon fiber" bikes are made of plastic. Just saying...

Be? Are you sure that you're not thinking of magnesium? Be is stupid expensive - I can't imagine a bike manufacturer doing that. I used to sell Focal speakers and they used Be for some of their upper-end tweeters. One speaker owner's kid poked out a tweeter and it needed to be replaced - that kid got a talkin' to.

There's clearly better materials (most likely synthetic!) available on this planet that we didn't discover yet. Time will come, one day! In the meanwhile, CF it is.

There are people in academic labs handling Be who have been killed by it. In very small quantities.
Magnesium is much less scary.
