I hope somebody with a tall Hilsen chimes in. Particularly someone who also has experience on another tall bike like a 68cm Ram or equivalent. I'm riding a 68cm Quickbeam and Atlantis and have no rigidity problems though I was told by Riv HQ the Hilsen has lighter tubing than either of those frames. So little info out there for frames in our size. It seems Zinn is using compact frames with the head tube and seat tube extending quite a bit over the top tube as his solution. I've also spoken with another builder who was proclaiming the sloping top tube as the answer. Of course, he was a pretty short guy...
