It's going to kind of depend on which hills you are talking about riding.

I used to have a Dolce Comp (2006) and sold it to a friend because it didn't fit me just right. I put over 1500 miles on it in 6 months though...so I got a good feel for it. The first thing I remember about my first ride on that bike is that the hills seemed way flatter! (This was when I lived in rolling hill country in NC). I think just having good working gearing really makes a HUGE difference. A bike that fits you well also really helps. The gearing on the Dolce Comp triple is pretty standard for a triple road bike and should make most hills much easier.

That said, I've seen some of the hills in Portland and even a triple isn't going to help in some cases! I'm 41 and about 30 lbs overweight, so I know how difficult it can be to climb. The best advice is to do what you can and don't give up. You will get better at it!
