Too technical for me huh? Too bad I'm a NASA rocket scientist.
The question was about frames not components. But do you really need 10 cogs? The world record 1 hour time trail was done on a fixed (1 cog). STI is nice, but certainly not necessary and also heavier than DT levers.
I also believe I mentioned better metals and tubesets.
GRP-graphite reinforced plastic (aka Carbon fiber)--not yet an established technology. Likes to delaminate unpredicably. I've personally owned two plastic bikes and both delaminated and failed.
