What baffles me about the second top tube on a road bike is what problem it is trying to solve? The Atlantis and bikes like the Co- Motion Americano are plenty strong enough to load up and take on an extended tour. Maybe on a very large size, like 67, a second top tube makes sense but it certainly seems like a beefier BB shell would stiffen a bike frame more. And why do we want a stiffer road frame anyway? Some flex makes a bike feel lively. I find the comparison to a Rambouillet confusing and maybe even misleading. I own a 62 cm Rambouillet and am certain that it would be less of what it was intended to be if a 2nd TT were added. A version of the Atlantis with a 2nd TT for extra heavy useage,...maybe, but not a Rambouillet.
I doubt that dbl TT makes sense even on a mt bike, but that is debatable. On a "road" bike no way. michael On Apr 17, 10:13 am, Eric Daume <ericda...@gmail.com> wrote: > I haven't seen any mention of the Soma/Amos update on the Riv page: > > http://www.rivbike.com/blogs/knothole_post/349 > > I was disappointed to hear this about the second top tube: > > *It is an "expanded" frame, meaning the top tube slopes up 6-degrees to > assure good comfy highish handlebars even if you buy a bit too small.
