Which 6603 Derailleurs and cassettes are right for me?

[chanc]

I think I narrowed it down to the 6603's. My cervelo 51cm has the FSA 50/39/30 130mm ck6020 triple crank. I am confused about which size front and rear derailleurs and cassette I should purchase to keep it 10 speed. I know I need the SL 6603 Shifter. Any help would be appreciated.

Hi there for the cassette you can buy any 10 speeds cassette from shimano so a cs-5600 (105) cs-6600 (ultegra) with a range from 12 to 25 or 27 ... as you wish but with a triple crank i will go with a 12-25 ... for the rear derailleur you shoud agai stay with a 105 (rd-5600 gs) long cage or an ultegra (rd-6600 gs) long cage and finaly the front derailleur you will need one for a triple crank a fd-6603 for an ultegra one or a fd-5603 for a 105 .... hope this help, you can alway take a look to the shimano web site to help you out ....
