Overview
About this bike
Some people would argue that this bike couldn’t possibly exist. An affordable road bike with a cutting-edge carbon fiber frame and fork and reliable components? You’re as likely to find a bike like that as you are to bump into Bigfoot riding a unicorn. Well, the core of Diamondback's Century 4 C is the same meticulous blend of carbon fibers and slightly relaxed Enhanced Performance Geometry that makes their higher-end models ideal for anyone looking to log big miles. A smart mix of affordable and functional components are what made this model possible. Highlights here include a Shimano Tiagra 2x10 drivetrain, Tektro disc brakes and HED Flanders C2+ wheelset. High performance doesn’t have to mean high price.
