Do you think bike frame size is less important these days?

both my bikes are roughly 23" (yes I will go old skool)
I am 6'6"

they are too small, but the raleigh (old skool frame, quill stem etc)
feels more upright than my Giant TCR which i feel massively streched out on
but neither are really the right height...

Custom frame ftw :)

saves up

I know how you feel, I'm 6'6" as well and really struggle to get ideal frames. Think its to do with having long legs and not so long femurs I need a steep seat tube angle and most OTP frames get slacker as they get bigger. Really considering getting a custom road frame as this is the bike I use the most and use for long distances. Waiting for cycle fit to get back to me on the price of custom Colnagos, think I'm dreaming though so I'll probably end up with either a titanium enigma or a carbon Glider.
