Yup, it'll give you really strong legs! I honestly didn't expect the road bike to make THAT much of a difference, but I am shocked. These are the differences I've noticed:

1) my "I'm not thinking about riding and not putting in any effort" speed has increased by about 3-4 mph

2) I can actually ride 19 mph on a flat road and not feel like it's all that hard (though I don't know how long I could keep it up. On my hybrid I never got past 16 mph).

3) Getting up hills is, dare I say it, almost easy. On my hybrid, it was always a major struggle.

4) The bike actually feels like it's riding itself, it's the strangest thing. My pt, who's a cycling coach, said that means it really fits me (and it should, it's a custom frame).

Transitioning from the hybrid to the road bike has completely changed my outlook on riding. I keep getting the urge to go out and ride hills!
