Sirrus X 2.0 (2027)

The Sirrus X isn’t just a hybrid—it’s your invitation to ride more, and to ride everywhere. By blending an unprecedented mix of comfort, efficiency, and nimble handling, it excels whether you’re sticking to the pavement or exploring the local dirt paths.

The Ride Feel: Smooth, Comfortable, and Efficient

The Sirrus X delivers the smoothest ride in its class. We’ve paired a slightly more upright riding position with high-volume, confidence-inspiring tires and an intuitive “one-by” drivetrain to keep things simple. It’s designed to be the bike you actually want to ride every single day.

Rider-First Engineered™ Precision

Every frame is uniquely crafted to ensure a premium experience for every rider. By specifically selecting tube sizes and carbon layups for each individual frame size, we achieve the perfect balance of rigidity, weight, and responsiveness. Regardless of your height, you’ll experience the world-class handling Specialized is known for.
