I think it is quite comfortable. After I changed the saddle so I was no longer getting chafed or numb parts. I was riding it 30 miles every day, and up to 40 miles, with maybe 15lbs of stuff in low rider bags and wasn't suffering any ill effects. Unfortunately I crashed with a skid on wet leaves a couple of weeks ago and messed my shoulder up. So I'm substituting geometry for riding tests at the moment. I don't think I'm worried on the comfort front, but also wondering if there is some efficiency boost in a proper set up.
Thanks,
Michael
