In the interest of fairness - I recently posted on a different list about shimmy. And mentiond there that my Atlantis does the shimmy the most. Of course, there is a lot of seatpost showing on that bike. Along with a lot of stem. And pretty fat tires, Schwalbe Big Apple 2.15. Oh, and I have the Nitto mini rack and often a Little Loafer on the bike. And all of this means nothing. It could be one of these things, and it could be none of them.
None of this also makes the Atlantis less than my favorite bike. And the most stable on downhill runs. But that's just me. And what do I know?
