I've got a Mountain bike for trail riding and then a road bike for road riding. For riding on paved greenway trails which would you suggest? My thought is the road bike since they are paved but I think there are a few small sections that are unpaved but hard packed. Will my regular road tires handle this ok? The tires on the MTB are knobby so I'm not sure it's going to be the smoothest ride but wasn't sure if the road tires would get torn up.
