I posted a similar note on another forum a year or so ago: I've probably had 20 or 25 bikes (been riding since college, and I'm 65 now). I bought an Atlantis from Rivendell for my midlife crisis four or five years ago, set it up about halfway between the way Riv said it should be and what I thought would work for me, and in about 12,000 miles, the only thing I've changed is the saddle, from a Brooks Pro to a B-17. If I had a billion dollars, I can't think of anything I'd change on it.
But of course when I went by Rivendell last year and saw a used Rambouillet in my size for a great price, I snapped it up... I'm done now, though. Unless I get a recumbent.
