No the seat stays and chain stay merged but the in stead ot having a solid triangle with drop out it has somthing similar to a big disc brake adapter.
that sound goofy as hell, but im sure that theres some kinda of function to it, perhaps you can switch between vertical and horizontal dropouts with it? so going SS is easier....
but if your gunna break that why wouldn't your seatstay or chainstay break too, or bend so that the bolt doesnt line up or something....sound complicated and therfore wont work....simple, stronger, lasts longer....
Replaceable drop outs is not a new thing, however more and more companies are producing bikes with them no and days. Why you ask? Simply put, you can run any style of wheel. DMR produces adapters for there bikes for maxle, standard 10mm, 12mm through axel..ect. It gives you the options of running a different type of wheel, but with the same spacing.

Really not the best thing IMO. Sure it might look cool as a matter of opinion, but if it does not NEED to be there it should not be there. We get along fine with horizontal drops so I'd stay away from them.
They're there due to the versatility. I think they're a wonderful idea. I'd rather have a dropout snap under heavy pressure than having one that won't snap under pressure, and bending my seat and chain stays.
