Default Any carbon fiber experts out there?

I've been drooling over Velocraft's and a bunch of other carbon fiber low racers I've seen on the web for a while now and I'm starting to get that old familiar itch to try to put something together. First I'm interested in building a front-wheel-drive, low, but semi-upright seat commuter/touring bike with a u-joint above the steerer tube to decouple the steering and propulsion.

Does anyone out there know anything about carbon fiber construction techniques as they would apply to recumbent bike frames? I'm also looking for any literature or web sites that explain the hows and whys and whats of carbon fiber construction.

I have been to this site many times: carbon! and it has been a big inspiration and source of info, but I need MORE!

Thanks,

TD

"the best" is clearly subjective. Ease of construction and cost effective designs such as the Calfee Stiletto, and Lug-and-glue df's like the high-end Merlin Cielo, are examples of efficient cf construction. For homebuilders and one-off prototypes, molds and "bladder construction" is usually cost prohibitive and time consuming.

By what pool, does your vast wisdom speak? Your a builder.. or... a structural engineer perhaps? And therefor qualified to say what is "the best" cf construction method for ALL designs? YES.. or NO? If not, your words are nothing more than personal speculation... and "pass the buck" links.

Oh really?... So tell me, what construction technique did the fastest bike on the planet employ for its cf frame?

Where's your bio?

Here we go again.... All talk and *appearently*... NO personal *hands-on* experience or design qualifications.

Obviously you are in a coma and you have no clue to bladder construction or what builders have been using the bladder system. My guess is you ride some lugged TourEasy for the easy lifestyle of slow riding.

More LINKS.... and no substance. All you *obviously* possess is a keyboard and the ability to cut'n paste.

Where's the beef Johnny NoCome?

And I know the difference between a digitally, self-taught phoney, and someone with last nights epoxy under his/her finger nails.
