The classic milestone for cycling enthusiasts is the century, and Diamondback’s Century 5 endurance road bike is ready to tick off the miles. Its Advanced Tube to Tube carbon fiber construction delivers a compliant ride and the Enhanced Performance Geometry takes the pressure off your low back and neck so you can comfortably enjoy the day. The full carbon fork helps smooth out rough roads and works with the tapered head tube to provide confident steering. A full Shimano Ultegra drivetrain ratchets up the speed and hill-climbing ability, and are accompanied by a HED wheelset with Michelin tires. Rounding out the Century 5 is a Prologo seat, FSA bar, and gel-lined bar tape.
