This is very elementary question: beside the difference in riding position (handlebar, saddle), tires (more slim), weight (lighter), what else make road bike faster? e.g. the chain? pedals? I've never tried a road bike... Does it feel less exhausting when pedaling a road bike? If so, what makes it so? Do you need to pedal less cycles to travel the same distance than hybrid?
Bottomline, I'm curious if I'll feel less effort and less tiring when riding a road bike. Thanks in advance.
