i'm planning on purchasing this 2012 Boyd B930 frame, the seller claims it is a de rosa open mold but there is no information online about the frame. i was wondering if anyone could identify what open mold design this is?
thanks

De Rosa/Ribble 838?

That looks very much like my old ribble r872 aka ribble stealth aka whatever the De Rosa version was called.

Edit. Though thus boyd has some integrated seatpost ?
