To put it simply: Diamondback's Century 2 is at home on the road. Designed to be ridden all day, every day, the aluminum frame features their Enhanced Performance Geometry. With a slightly taller headtube than a road race bike, it helps the rider maintain a more upright, less fatiguing body position. With discomfort out of the way, you’re guaranteed to enjoy every part of your ride more—the Century 2 delivers. Shimano's buttery-smooth 11-speed Ultegra drivetrain, hydraulic brakes, and 28c Michelin tires on HED wheels complement the bike’s platform and reinforce its performance. For many of us, riding 100 miles is an exercise in surviving. The Century 2 turns those long rides into something to look forward to, not to dread. If you’re an endurance rider or someone that prefers a more upright riding posture, this bike does not disappoint.
