I had some 83mm Spanish BBs made for frames with super short chainstays. I have 83mm Euros on a few of my bikes and they work out fine with a 6" Profile spindle. I also just got some butted (27.2mm post) seat tubes which will work with frames that have a higher standover-12- 14" center to center
Dragged the old Kona out and learned a few things by reverse engineering the pivot points. The old front triangle was due for a catastrophic failure... this one should last longer than the rest of its parts. A few improvements over the original are a 1.2mm thick, heat treated down tube, a 31.6mm post size (for my current dropper) and a lower stack height achieved with the integrated headtube.
