Description
Experience the Sirrus X, a versatile marvel, seamlessly mastering pavements, dirt trails, and everything in between with unmatched comfort, efficiency, and agile handling. With its smooth ride, courtesy of larger tires and a slightly more upright riding position, complemented by an intuitive one-by drivetrain, the Sirrus X sets new standards for performance. Crafted with precision engineering, each frame boasts rider-first design, ensuring an optimal balance of rigidity, weight, and responsiveness for the ultimate riding experience, regardless of size. Enjoy class-leading lightweight construction, exceptional pedaling efficiency, and precise steering, all culminating in confident, nearly telepathic handling. This iteration is even lighter and faster, featuring an added A1 alloy fork, a wide-range 1x9 microSHIFT drivetrain, and more powerful hydraulic brakes with a premium two-piece crank design for enhanced braking power and durability, even in the toughest conditions.
