if they offered a 650B option this would be very attractive.
I mean, if you were riding this in a cyclo cross race... you wouldn't really be dealing with the 'where can I find a 650B tire? I just got a flat!' issue. And if you were riding this around town cause it's ' so darn comfortable' you don't really have to worry about availability of tires. That frame is begging for a 650 wheel. Soma B-Lines would be perfect.
(still can't seem to find a price for it)
(never mind, found the price... hmmm not bad)
