Not so long ago, fast bikes came in one flavor: painful. As in, painful to ride for anything longer than an hour at a time. Super steep head angles, sprawling top tubes, and a spine-rattling ride quality were the norm. Those traits might be fine for a rare few, but for the rest of us? We're not all sadists. Well, the Century is an entirely different flavor of fast — the kind that's actually enjoyable. We carefully blended high- and low-modulus carbon fiber and obsessed over the lay-up of those carbon plies to create a bike that is still light and blazingly quick, but also impressively smooth in the saddle. The Century 5C is well-appointed on the component side of the equation as well. Shimano's 105 2x11 drivetrain delivers crisp shifts and their hydraulic disc brakes have a well-earned reputation for power and reliability. Fast doesn't have to mean "painful." With the Century 5C, fast is simply, well, fast. - Our hand-built, carbon-fiber frame is stiff where you need it, compliant where you want it. It's also Di2 compatible - Enhanced Performance Geometry provides a comfortable and stable ride - Continuous Fiber Technology full carbon fiber fork and tapered head tube enhance steering precision and vibration damping - Thru-axles front and rear equal impeccable tracking and stability - Closed Circuit Cable Routing is clean and aero - Shimano 105 2x11 drivetrain offers great value and performance - HED Flanders C2+ disc wheelset is quick to accelerate and durable
