PoshBikes did a 6kg bike (I think) but even they say that it's more of a statement piece vs. a rider. I wonder if you could get this newer style bike down below 7kg and still ride it w/o worrying about stuff breaking. If anything, they have some new ideas on there that move the business forward as I'm sure someone will try to copy some of those details & sell for much less.
