Which Groupset?

so i have a triple on the front on my cervelo (i know, kill me). i really do want to change out the crankset but i cant go to a triple without getting new levers and mech can i? ultegra from '09 btw.

As Rod says, you might be able to get it to work, depends on being able set the limit of the front derailleur correctly maybe. But 6600 does have separate specific FD and STIs for the triple chainset. Try Merlin or Total Cycling for 6600 parts.
