That's the same drive train on two of my cycle cross bikes and I love it for general road riding as well. I have had no problem with lightly loaded touring and that same drive train but I will say I've only used that set up when I knew major steep climbing was not in the picture. Get back with us as to how the bike set up works out for you.

Btw, Samox makes a G3 crankset 44-28 if you need just a little more low
