need to disagree with you again sirious...while it may be able to be made into a decent fitting bike, at 5'9 you should really be looking at a 54cm. FWIW, I am 5'9.5" and was professionally fit by my LBS for my brand new Tarmac(my allez elite got totaled in an encounter with a car) and I landed smack dab in the middle of the 54. Unless you have odd proportions, you should really look to a 54 IMO
