Been riding a hybrid for exercise but recently started shopping for a road bike so I can keep up with friends on faster road bike during casual rides - not interested in racing. Stopped by LBS in my shopping and the guy tells me that the road bike is better exercise because it is more efficient. I know it is more efficient in terms of speed and milage but that is not my objective during exercise.
From a calories per hour or general biking exercise standpoint, would the type of bike make any difference? I have been assuming that my calories per hour and general exercise benefits would be equal no matter what type of bike I am riding. One hour on a hybrid = one hour on a road bike.
Any evidence to the contrary?
