Specialized Sirrus X 2.0 Step-Through Hybrid Bike 2024
The Sirrus X opens up new possibilities for riders, offering a comfortable and capable experience that encourages exploration. This versatile bike, designed for diverse terrains, features confidence-inspiring tires, an upright riding position, and a user-friendly one-by drivetrain. With ample mounts for racks and fenders, it goes beyond a pavement companion and excels on gravel adventures. The Sirrus X prioritizes rider comfort with scientifically tested and ergonomically engineered components, including the Shared Platform Body Geometry saddle, handgrips, and pedals.
Built on a lightweight A1 Alloy frame with clean internal cable routing, the Sirrus X is 3.5lbs (1.7kg) lighter than comparable bikes. Its hyper-intuitive 1x8 wide range gearing ensures maximum control, complemented by powerful hydraulic disc brakes for confident stops. With the ability to effortlessly navigate rough terrain, thanks to fast-rolling Specialized tires, the Sirrus X is a reliable and inspiring choice for riders seeking a do-it-all bike.
