Overview
About this bike
The Century 3 is a shot across the bow of conventional design — a fast bike you can ride quickly for hours on end in complete comfort. Its Enhanced Performance Geometry incorporates a taller head tube to take the stress off your neck and back and provide a more comfortable fit. The lightweight 7005 aluminum is custom-butted and beautifully formed to deliver a balance of strength, durability, light weight, and sleek looks. Diamondback's premium aluminum model is equipped with an amazing component group for its price that includes TRP disc brakes, a 2x11 Shimano 105 drivetrain, and HED wheels.
