i just purchased a Ciocc Pro Race 16.5 EOM.

I currently own two other bikes. One of my bike is a alum frame (daily rider) and the other i have been storing so when my daily alum bike craps out. I want to swap out all the parts and components from the bike i have been saving and throw them on the Ciocc. the bike i have been saving is a 2000 trek madone USPS

I want a steel bike to ride and train, my question is can i remove all the parts from the trek madone and put it on the ciocc. I did see that the ciocc uses italian threads (dont know what that means exaclty but ..). Will that effect anything? can i build the CIocc with all the parts from the madone?
