I’m 6’4" and ride 60cm. Have managed to find/purchase a couple of Ridley frames here, but not through regular retail outlets. Took a while and a bit of digging around by contacts in the trade.
I was lusting after the Ultegra one, for sure. “Only” about $15k more.
They also sell an aluminum frame Striker Lite model with 105 for $36k or Tiagra for $27k. Not bad deals, but with Carbon as cheap as it is…

I have a Giant bike for three years now, and I still like using it.
