The top end seems a bit low for a road bike, but unless you want to pedal past 30 mph you should be fine. The low end should be nice for any climb down to about 4 mph (slower than that, you start to fall over anyway!) The close spacing for your chainrings will allow you to fine tune your gears and use less front shifting.
edit: oh if you have 650c wheels, the gearing will be even lower. What size tires will you be using on them?
