You need a longer cage front to go triple, that and in most cases (Ultegra and 105 being two of them) you need new shifters too. Big$$ Try to do it with the cassette.
My Roubaix gets by with higher gears than my heavy bag laden commuter. I rode it up Mt. Diablo andwas in super low gears carrying a load. My Roubaix, no problems in not-the-lowest gear.
