The Specialized Sirrus X 3.0 is a lightweight and versatile fitness bike designed for smooth handling across pavement, dirt, and mixed terrain. A wide-range 1x9 microSHIFT drivetrain with an 11-42t cassette ensures efficient gearing, while confidence-inspiring larger tires and a slightly more upright riding position enhance comfort and control. Hydraulic disc brakes provide reliable stopping power, and the A1 alloy fork keeps weight low for improved speed and agility.
