I grew up on a big box store mountain bike. I want to get a road bike for my commute, but I'm curious about the limitations I'll experience.
I know the benefits of a road bike: lighter weight, less rolling resistance, aerodynamic riding position, etc.
But I want to learn about the limitations: I'm mainly concerned with the ability to hop up and down from curbs and occasionally riding through some mulch and grass.
Is a road bike's frame less tough than that of a mountain bike? On my cheap mountain bike, I can (though I usually don't) hop over and down from curbs at full speed. Would I have to be more ginger with the road bike or would curb-hopping be recommended against altogether? Would the drop bars make it difficult to hop over curbs at all? And would a road bike's tires be unsuitable for anything off-road? Any other limitations?
