Naw, speculation is fun as long as you acknowledge that's what you're doing. I just don't want to read the same old arguments about frame materials here or get one of those trite "skeptical of the Wright Brothers" lectures.

Not so fast on the polymer unobtainium (PU)
This is an industry that grows incrementally.
Past the 'concept' bikes, version 1 of PU must be 5% stiffer, while maintaining vertical compilance. And 30g lighter in size M. Than the latest CF wonderbike.
Road race Version 2 must win Tour Dr France.

Screw the UCI, let's get rid of the seattube again - akin to Kestrel's 500 of old. Heck, get rid of all the 'tubes' replaced by thin PU sheets. But maybe compact that geo with a sloping tt? Super thin seatpost and handlebars? Dump th Scotts!


.......or some other not-too-too-crazy design

Polymer Unobtanium rims are next, too.

What I want to know.
Who is working on a material to yield a lightweight 20mm road tire with the compliance of today's 28mm tire, without damaging rims?

Could drive train parts be made from such a hard plastic?

if it can take the stress of being threaded, it could be an alternative for spokes.

According to the article, it's supposed to be cheap, btw.
The marketing geniuses won't even use the word plastic because it has a cheap and fragile sound to it, they'll have to come up with some other word that will make it sound very high tech, something along the lines like Nanotechnology Composite, or maybe just Nano Composite, or 3D Nano Composite and give it a fancy abbreviation of just "frame tubes made of 3DNC". Trust me, the marketing people will come up with something to tickle our minds into buying their nonsense.

Wasn’t there a stamped steel frame that was supposed to be as light land stiff as carbon fiber?

I never heard of it again.

Rodriguez still makes the Outlaw, and if you get the RL model it weighs 13.5 pounds, of course it will cost you $11,000.

As a mechanical engineer/designer I keep looking at this and it just gets worse every time! What were they thinking? Why on earth would you remove the seat tube, but keep the rest of the frame pretty much as a standard configuration? It makes no sense. It's just less efficient for no obvious gain. I can understand bikes like the Softride with a cantilevered top tube. But this just looks wrong!

YMMV.
there were many scoffing mechanical engineers at Apple.
some got wealthy being wrong or overruled.
not sure anybody got rich at the original Kestrel.
design, over function, may sometimes define classic - in my looks book.

BTW, did anyone else suspect this was a joke when they saw the name "Carbon P. Dubbs"? I had to google that:
https://digging-history.com/2016/01/...-riches-story/

Real guy, really funny name.
Do you remember the carbon fiber racing yacht debacle, millions were spend on new racing catamarans built solely out of carbon fiber and they all sunk? Hopefully they will do a little testing before extolling the virtues of this new product

Good point. Maybe a mini electric motor in the BB and a battery in the seat tube could bring it up to minimum weight and keep the weight low.

Oh yeah…
