I'm considering the Felt FW3 for my wife. The only thing that concerns me is that its a double (compact double). Would she be able to get up the hills ok on a compact double and like a 12-27t cassette? Or is triple the way to go? I can get this bike new for a discount, that's why i'm considering it. Or i'm looking at a new Trek 1600wsd, or a used 2007 Dolce.
