Once upon a time, I had a road bike with a triple. And there were a few occasions when I was very grateful. I remember one day getting passed on OKW by a girl with an H seeding... and I couldn't hold her wheel! Also, there were a couple of Double Centuries where I wouldn't have been able to ride slowly enough to stay with my team with anything bigger than 30x25.
In due course my triple STI lever broke, I replaced it with a double, and haven't missed the 30t since. In fact these days I use the bike for commuting and leave it permanently in the 52t.
I think these days I would prefer a compact crankset, e.g. 50-34, with an 12-25 cassette. It gives almost as much range with a lot less front shifting which seems to make more sense.
Oh, by the way... that Dale is a great looking bike! Enjoy it!
