Ambrosio Crono F20 was my first thought and incidentally I would get it cheaper than the Escapes and just slightly more expensive than the Kinlin, if at all, but Iīm afraid it would be too flexible.
And the non-machined flanks, I donīt know.
I've been riding the snot out of a pair of Crono wheels I built up a year ago. There is very little you have to worry about as far as stiffness and strength are concerned if you aren't fat or really big.
