Gearing wise, hard to beat the Roadlite CF 9 LTD. That 46t crank with 10-50 cassette is wide and fast, on a very lightweight hybrid. The geometry is also a low 1.4 stack/reach ratio like a drop racer. Only thing is to throw out those G-Ones for a GP5k or Pro1 slicks and it will fly. I've ridden it for 10 miles or so at a stretch, but not sure how comfy the geometry is for longer distances, being flat and low. My neighbor has no probs with 30 mile rides with it.
