I recently had a discussion with an experienced frame builder and it came up that tubing diameter has a bigger effect than the thickness or thinness of the tubes; at least with common wall thicknesses. Apparently there are online calculators that show flex characteristics of a tube and this is where that idea can be verified.
I'm certain the outside diameter of the Atlantis tubes are the same as always. So wether its tubes are a bit thinner/thicker is probably not that important. We didn't discuss the effect of butted vs straight gauge so I can't comment on that. Based on how folks seem to love even the straight gauge Rivs, my guess is it doesn't have a very strong impact on the overall experience.
