However, the G1055-D seems to have beefy chainstays, that don't seem flexy at all. What are your thoughts on this type of suspension? Is it going to work, or is it just a gimmick?

I do agree that chain stays are pretty beefy.  That said, this is just a render and we have no idea what the finished product will look like.  Not very many bikes have chain stays that are as beefy as those in this render.

Cannondale site has very little marketing claims on how the flex is created but several reviews I found online report that the flex is achieved more from the seat stays.  This makes sense as you probably would not want too much flex in the chain stays as this would rob you of power.

"According to Cannondale, the combination of the seat tube-mounted pivot and integrated flex zones in the seat stays, seat tube and rear section of the top tube provide active shock absorption at the saddle and rear axle." from granfondo mag.

If the Topstone had 50mm tire clearance I'd probably get one and try it out but 45mm is just not enough IMO.  I'd prefer 55mm but I guess that's not happening.
