The future of riding is here. Feel the difference with the all-new Sirrus. With a lightweight carbon frame, this is the next generation of lightweight comfort and speed.
The Sirrus is alluring in aesthetics but even more superior in performance. Meticulously crafted with performance features and a comfort-focused design, Sirrus’ lightweight carbon frame includes our Compliance Junction — enabling a new degree of handling that’s completely unconventional in such a comfortable bike.
Rider-First Engineered™: Like all Specialized carbon bikes, the geometry of each frame is uniquely crafted. This means that for every frame, each tube size and carbon layup is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness to ensure that no matter what size you’re riding, you’re going to experience the world’s best ride.
Comfortable: The extraordinary performance of the Sirrus Carbon frame begins at its heart, the Compliance Junction. It’s been designed to have just the right amount of flex and forgiveness across the carbon frame without sacrificing performance or efficiency. The result enables next-level maneuverability for enhanced all-day comfort. Future Shock, Specialized’s unique suspension design, prevents harsh frequencies caused by bumps in the road from reaching the handlebars. The Sirrus Carbon is forgiving, flexible, and quick enough to move at the speed of life.
Versatile & Customizable: Equipped with rack, fender, and top tube mounts, you can make the Sirrus your tool, your transportation, or both. With tire clearance up to 42c, you’ve got plenty of room to tune your ride for whatever comes next.
