The Sirrus X 3.0 Step-Through offers an unprecedented combination of comfort, efficiency, and nimble handling, excelling on pavement, dirt, and any terrain in between. This bike provides the smoothest ride in its class with bigger, confidence-inspiring tires, a slightly more upright riding position, and a super intuitive one-by drivetrain. The geometry of each frame is uniquely crafted with each tube size specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness, ensuring the best ride experience across all frame sizes. Class-leading lightweight construction, exceptional pedaling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics. The Sirrus X 3.0 is even lighter than the previous generation and faster thanks to an added A1 alloy fork.
