Here's the frame I made with couplers a few weeks ago. I'll be building up the whole bike including wheels pretty soon. The tubeset is almost all Columbus Nivacrome.
This is not a touring frame but a rack will fit . My hope is that this travel frame will feel nice and snappy-fun to ride just about anywhere in the world......that will be handy as this bike will most likely circle the globe in travels over the next decade or so.
