My guess is the Atlantis has thicker wall tubing than the other designs, and would not benefit from adding another top tube. Riv has stated that the Atlantis frame & fork weigh roughly a pound more than their other bikes. It's been billed as their most versatile bike, capable of use as a loaded tourer, commuter, MTB, etc. The design, as- is, meets its intended purposes.
Personally, I've over-loaded mine with more junk than I need, gone down dirt fire roads fast enough to scare myself, dragged it onto trains, packed & shipped it by air & truck, and haven't hurt a thing (paint excluded!). Why mess with success? dougP On Sep 12, 8:48 am, Steve Palincsar <palin...@his.com> wrote: > On Mon, 2011-09-12 at 08:23 -0700, opa...@gmail.com wrote: > > I didn't search much for this information, but I couldn't find it on > > Riv's site anyway..
