I think having a stable of bikes can really help. That was and is a brilliant idea.

Have a vintage Italian steel bike with old Campy friction Nuevo Record on it. Have a recumbent. Have a good stiff high end aluminum tandem, have your road single, and a mountain bike.

Every bike will fit your 'mood'. Whether you want to hammer, cruise, enjoy a ride with your partner at equal pace, or just pretend you're assaulting the mountains to become the first American to win the Giro.
