I am currently riding a 2005 Schwinn Rocket Pro full suspension bike. The rear shock is a Manitou Radium R Air with no lockout. Yesterday I decided to hop on my friends Specialized hardtail and ride it for a few minutes. I could really tell a difference in how much more energy I was getting per pedal push on the hardtail. I have read where people call this pedal bob, but I really don't feel any bobbing. My question is, are there full suspension bikes out there that have the same pedal effeciency as a hardtail? If so, which rear shock settings work the best?
