I also just bought an 04 Specialized Roubaix Pro 54. However, I am switching out several components. I am getting an FSA Pro Elite Compact Carbon crank 50/34 and switching out the Dura-ace cassette 12-25 with a 12-27 and an FSA platinum Ti bottom bracket ISIS. I am also getting a Fitzk Arione saddle and Specialized S-works all-condition 700c-25cm tires. I hope to pick the bike up this weekend. I have a bad back and need lower gearing to get up the hills. I am also getting Look Keo Carbon pedals, Shimano R151E shoes, Profile Design Karbon Kage bottle cage and Barberi CarbonOne frame pump. How much does your stock Pro bike weigh and what frame size is it?
