Framebuilders - Road Bike Geometries

Hey guys, I am beginning to build carbon road bike (and mtb) frames. I am wondering what your opinions are about geometries for road racing bikes. What sort of geometry would a pure racing bike, putting comfort aside, to be the most efficient shape have? Also, how can the geometry of a road bike increase comfort without reducing too much performance? So, all I want to achieve is to work out what geometry a pure hard out racing bike would have and the geometry of a bike for us mortals, where comfort is all important.

Tim Paterek has a book that is considered one of the bibles for frame construction. Google his name and his site should pop-up right away.
Here is a link to Dave Moulton's blog. On his blog he describes a bit of frame building geometry and history. An excellent place to start to get some context.
BTW - are you on the North or South Island?

I think the bike geometry question is an important part of your plan. The vast majority of composite frames have settled on geometries that are easy to reference, limited in variation and not what I would do. You also have to decide on what you are going to do for a fork, buy a pre-made or build your own. If pre-made then you have to work around what you can get. Personally I think that the bikes of today are often too short, even the pros do not need bikes this short, but they have adapted to them.
Thanks for the info, I will have a look at those guys you have mentioned about.
I might end up getting Paterek's book in the end cause I could get some good tips out of it.
I will probably end up making my own fork too.
I am in the North Island Radshark.

Nice. I visited awhile back. The far north was my favourite spot. Unbelievable pristine seascape and nice people. I stayed for a bit near Anderson beach. It was pure bliss..
Someday I'll return...
Good luck with your frame!
Great! Its a long way from Canada though isn't it.
