I don't know where you'd get a bike so tall and with such a short top tube - 56 is dead short for a 59 isn't it.
The Cannondale CX9s are lovely frames but not easy to get hold of ;-) but they have a sizing issue (the 58 i ride is is big as any other brand's 60 and much bigger than a Columbus 59!) - Their sizing is below.
I really got on with the crosslight EVO to be honest but the paintwork was a shocker. Horses for courses.
