Diamondback's Century road bike incorporates cutting edge technologies and features at an affordable price. The frame uses their Enhanced Performance Geometry, and custom formed and butted aluminum tubes come standard. This results in a ride that's the best of both worlds, compliant and smooth without compromising performance. The component group they chose is up to the task, too: Tektro disc brakes and an 18-speed Shimano drivetrain make this bike stand out even more in its category. For beginning roadies or those who prefer a fatigue-fighting upright riding posture, the Century is an easy choice.
