sounds like a great new frame,
if i read it right i can have winter bike with disk brakes and use a 48x36 crankset an 18t sprocket and an alfine tensioner, to get around 15" to 103" gear range with a rohloff hub (i know the purists won't approve, but i need a wider gear range than a vanilla rohloff will supply, a patterson crankset sounds better but they are scarce and pricey this side of the pond)
and if I tour i can swap it over to 9 speed 11-34 and 48,36,22 crankset? until i am confident in the rohloff's reliability?
I'd get to try a rohloff and if i don't like it i'd still have an Audax
