I am the most proportionate 6' tall guy you will ever meet.
This is going to be a shuttle run/Northstar bike, so not much pedaling involved.
Bike seller is far away in the remote part of Santa Cruz Mtns and It's a 2hr. drive.
Any input might save me some time.
Thanks,
Greg

my guess is no. im 5'9" and I am borderline on most brands/models between med and Lrg. at 6ft tall id say you are perfect for a Large frame.

If it helps, Brendan Faircloth raced a medium and he is also 6". Im 5' 11.5" (seriously) and my 2011 medium is perfectoooooooo!

My last two Demos were also mediums.
